The front view camera module permanently monitors the serial data bus for error messages. When a malfunction is detected by the front view camera module, the system will be disabled and an error message will be stored in the front view camera module disable history buffer which is used to store information about the front camera features that are disabled.

1. Ignition ON
2. Front view camera enabled

The front view camera module detects a malfunction.

1. The front view camera module is disabled.
2. The front view camera module disable history buffer stores information why the system was disabled.

The condition for setting the DTC is no longer present.

Diagnostic Aids

The front view camera module disable history buffers are used to store information about the front view camera module features that are disabled. The Buffers will only update if the disable condition changes.

Example: If the data received from the steering wheel angle sensor is Invalid across many ignition cycles then it will only appear in 1 history buffer and not all history buffers. If this condition is the current reason why the front view camera module is disabled then it will be set in front view camera module disable history buffer 1. If a new reason occurs, such as vehicle speed validity is invalid, then the invalid steering wheel angle sensor fault will shift into disable history buffer 2 and vehicle speed validity invalid will be in disable history buffer 1. Since there are only 4 disable history buffers, the invalid steering wheel angle sensor will age out if 4 other disable reasons occur since the last invalid steering wheel angle sensor event occurred. Front view camera module disable history buffer 1 contains the current reason that one of the front view camera module features is disabled.

The front view camera module disable history buffers can display the following values

1. Lane Departure Warning Indicator Malfunction
2. Lane Departure Warning Switch Malfunction
3. Camera Obstructed
4. Accelerator Pedal Position Out of Range
5. Driven Wheel Speed Signal Invalid
6. Non-Driven Wheel Speed Signal Invalid
7. Brake Pedal Moderate Travel Signal Invalid
8. Brake Pedal Initial Travel Position Achieved
9. Lost Communication with Steering Wheel Angle Sensor Module
10. Invalid Data Received From Steering Wheel Angle Sensor Module
11. Forward Collision Alert Switch Malfunction
12. Clutch Pedal Position (CPP) Sensor Performance
13. Clutch Pedal Position (CPP) Sensor Performance
14. Transmission Gear Engaged
15. Acceleration Sensor Longitudinal Signal
16. Invalid Data Received From Yaw Rate Sensor Module
17. Power Mode Controlled by Backup Device
18. System Power Mode
19. Overvoltage
20. Undervoltage
21. Undefined

The lane departure warning system is controlled by the front view camera module mounted on the windshield. The lane departure warning is enabled and disabled through a switch located in the steering wheel. When enabled, the front view camera module will illuminate the amber indicator located in the switch.

When the system is operating and can detect the lane markings, the front view camera module will request via serial data communications that the instrument cluster illuminates the green lane departure ready-to-assist indicator. If the front view camera module detects that the vehicle unintentionally crosses a lane marking without the turn signal being used, the module will request the vehicle direction display to flash the amber lane departure warning indicator. An audible warning will also sound three times when the amber lane departure warning indicator in the vehicle direction display is flashing.

Certain factors will affect the operation of the lane departure warning system. When the system is operating properly, the green lane departure warning indicator will illuminate on the instrument cluster. This indicates that all of the required operating conditions to permit lane departure warning have been met. The green lane departure warning indicator will not appear when the system is having difficulty seeing the lines on the road or if the view of the front view camera is blocked with mud, dirt, snow, ice, or slush, if the windshield is damaged, or when weather limits visibility, such as while driving in fog, rain, or snow conditions. This is normal operation, the vehicle does not need service. Additionally, lane departure warnings may occasionally occur in a properly operating vehicle due to tar marks, shadows, cracks in the road, or other road imperfections. This is normal system operation and the vehicle does not require service. The driver information center may also display Lane Departure System Unavailable due to the temporary conditions listed above.

Additionally, the Front View Camera Disable History can give useful hints about what affected the operation of the lane departure warning system. For the Front View Camera Disable History, please refer to DTC B1011 .

The forward collision alert system is controlled by the front view camera module mounted on the windshield. The forward collision alert system is always active and operates at speeds above 40 km/h (25 mph). When the system detects a vehicle in the path ahead, the green vehicle ahead alert indicator in the vehicle direction display is illuminated. When approaching another vehicle too rapidly, the collision alert symbol will flash in the vehicle direction display and the radio will simultaneously give an audible alert sound. The red collision alert display will stay continuously illuminated if the vehicle ahead remains much too close. These actions are requested by the front view camera module via serial data. The forward collision alert switch is part of the left steering wheel controls and is used to adjust the timing sensitivity of the front collision alert system.

Certain factors will affect the operation of the forward collision alert system. Forward collision alert does not warn the driver of any objects that are not detected as a vehicle, like e.g. pedestrians, animals, signs, guard rails, bridges, construction barrels or other stationary or slow moving objects. In some cases the camera may detect a vehicle that is not in the path ahead, or the system may occasionally provide unrealistic alerts. This could respond to a turning vehicle ahead, guard rails, traffic signs, or other stationary objects. This is normal operation, the vehicle does not need service. When the system is operating properly, the green vehicle ahead alert indicator will illuminate on the vehicle direction display when the system detects a vehicle in the path ahead. This indicates that all of the required operating conditions are met. The green vehicle ahead alert indicator will not appear when the system is having difficulty seeing other vehicles on the road or if the view of the front view camera is blocked with mud, dirt, snow, ice, or slush, if the windshield is damaged, or when weather limits visibility, such as while driving in fog, rain, or snow conditions. This is normal operation, the vehicle does not need service.

Additionally, the Front View Camera Disable History can give useful hints about what affected the operation of the lane departure warning system. For the Front View Camera Disable History please refer to DTC B1011 .

The ultrasonic parking assist system is designed to identify and notify the driver of an object in the vehicle's path when reversing at speeds of less than 8 km/h (5 mph). The distance and location of the object is determined by four object sensors located in the rear bumper. The parking assist system will notify the driver using an audible signal through the radio.

When the "Park Assist Off" or "Service Park Assist" message is displayed in the DIC the disable reason is stored in the Park Assist Disable History.

The scan tool Park Assist Disable History parameters are a list of the previous reasons the parking assist system was disabled. These parameters may help in the diagnosis of an intermittent concern or a customer concern which is the result of normal system operation. The following is a brief description of potential causes which may aid in diagnosis

1. 3Disable - The parking assist system has been disabled through the audio system personalization menu.
2. Hitch/Object Attached - The parking assist control module is detecting an object that is attached to the vehicle. Common items such as a hitch receiver, trailer, object hanging out of tailgate, lowered tailgate, or a bicycle rack may cause this concern. If the customer does have a ball mount attached to the factory hitch, then refer to Owners Manual and "Vehicle Personalization" to enable "Towbar" option. Additionally, damage to the rear of the vehicle or a misaligned sensor may cause this concern. If the vehicle is damaged in a manner that causes the sensor to detect the bumper itself, the parking assist control module will interpret this as an attached object and disable the system. Carefully inspect the bumper, bumper mounting surface, and sensor retainers before continuing with normal diagnosis. After the detected cause has been addressed the vehicle must be driven at speed greater than 40 km/h (25 MPH).
3. Reverse Overspeed - The vehicle is travelling too fast in reverse at speeds of greater than 8 km/h (5 mph).
4. Inhibit - The parking assist control module has lost or received invalid GMLAN signal(s).
5. Sensor Disturbance - An outside interference is causing sensor movement. Such interference may be caused a heavy pounding, like that of a nearby jackhammer, or large changes in pressure, such as a large truck's air brakes.
6. Sensor Ring Time - If the sensor fails its own diagnostic initialization the parking assist control module will set this error. After the detected cause has been addressed the vehicle must be driven at speed greater than 40 km/h (25 mph). The following is a list of reasons this cause may have set: One or more of the sensors may be blocked by snow, mud, ice, or other debris. This might happen after going through a car wash in cold weather. Silicone insulator surrounding sensor maybe missing, cut, or twisted. Improperly installed sensor, sensor maybe be crooked due to a tight wire harness. One or more of the sensors may be scratched or the paint maybe chipped. Excessive paint thickness on a sensor may cause an excessive sensor ring time. When replacing or refinishing a sensor, do not apply an excessive amount of paint or clear coat.

When the transmission is placed into REVERSE, a 12 V signal is sent to the rearview camera indicating that camera operation is requested. Ignition voltage and ground are supplied to the rearview camera. The rearview camera sends video information to the radio through a video signal + and a video signal - circuit. A grounded shielding also wraps the video signal circuits to reduce electronic interference which may degrade the video signal and cause a distorted or otherwise degraded image.

A poor video image can be caused by ice, snow, and mud buildup on the lens of the rearview camera. Also, extreme lighting conditions can affect performance, such as operating in the dark or with bright sunlight shining on the camera. Extreme high or low temperatures can also affect the image quality. An open in the shield of the video signal circuit can also cause a distorted screen.

Front View Camera Module Calibration

The calibration process for the front view camera system is necessary when a front view camera module is replaced by a new one. This process shall not be required when only replacing the windshield and the front view camera module has been mounted again properly. This is a self-calibration procedure, which starts after the SPS configuration and setup is done. This process shall be completed within 3-10 min when the correct driving conditions are met.

If conditions are not met correct, the front view camera module shall continuously run the service point calibration until successfully completed. This process shall work across ignition cycles and shall not be required to be reinitialized at start up.

When this process is initiated on modules with the lane departure warning feature, the front view camera module shall command the lane departure warning system amber indicator on continuously until the alignment is completed. Once alignment is complete, the amber indicator will clear automatically.

Operate the system in the following conditions until the alignment is complete

1. Clean windshield.
2. Avoid lane change.
3. Drive during the daytime.
4. Lane departure warning system is ON.
5. Maintain vehicle speeds between 56-90 km/h (35-56 MPH).
6. Ensure the road contains visible references (well defined lane markings, curbs, guard rails, fences, buildings, etc.).

When the calibration is complete, the amber indicator will clear automatically, if well defined lane markings were seen and the vehicle speed was between 56-90 km/h (35-56 MPH). Then the system is ready to assist.

One or more of the following conditions may increase the length of time required to complete the self-calibration procedure

1. Heavy traffic
2. Maintained roads
3. Curves in roadway
4. Poor contrast lane markings
5. Botts' Dots type lane markings
6. Operating the vehicle speed is greater than 90 km/h (56 MPH)
7. Driving through snow or fog, driving at night, or driving directly into the sun

Conditions that will prevent completion of the self-calibration procedure

1. Operating the vehicle with speed less than 56 km/h (31 MPH)
2. No visible lane markings

Object Detection Description and Operation (UD7)

The ultrasonic rear parking assist system is designed to identify and notify the driver of an object in the vehicle's path when reversing at speeds of less than 8 km/h (5 MPH). The distance and location of the object is determined by 4 object sensors located in the rear bumper. The parking assist system will notify the driver using the parking assist indicators and an audible beep signal through the radio.

The rear parking assist system is made up of the following components

1. Parking assist control module
2. Rear object alarm sensors
3. Parking assist indicator

Parking Assist Control Module

The parking assist control module provides an 8 V reference and a low reference to the four rear parking assist sensors. The parking assist control module receives individual signals from each of the four sensors and determines the location and distance of an object based on these inputs. When an object is detected, the parking assist control module will illuminate the appropriate LED on the parking assist indicator and send a serial data message to the radio requesting an audible alert.

Rear Object Alarm Sensors

The rear object alarm sensors are located the in rear bumper of the vehicle. The sensors are used to determine the distance between an object and the rear bumpers. Each sensor emits an ultrasonic frequency which is reflected off object located behind the vehicle. These reflections are received by the sensors. The time difference between when the frequency was emitted and when the reflection is received, known as sensor echo time, is used to determine the distance to the object. The sensors report this information to the parking assist control module.

Parking Assist Indicator

The parking assist indicator is located in the interior rear of the vehicle and is visible through the inside rearview mirror. The indicator contains three LEDs: two amber and one red. The parking assist control module controls these three LEDs as a visual indicator of how close the vehicle bumper is to an object. The parking assist control module supplies voltage to each of the LEDs and commands each LED on by supplying an individual ground.

Rear Parking Assist Operation

When the vehicle is first placed into reverse, the rear parking assist system performs a bulb check. During the bulb check, the all three LED located in the parking assist indicator will illuminate for approximately 2 s to indicate that the system is working.

When backing up at speed of less than 8 km/h (5 MPH), the system is constantly monitoring for object of interest located behind the vehicle. The rear parking assist system can detect objects greater than 7.6 cm (3 in) wide and 25.4 cm (10 in) tall. The system cannot detect objects below the bumper, underneath the vehicle. If an object is detected, one of the following will occur

1. If the object is 1-2.5 m (3.3-8.2 ft) away from the vehicle, the amber outside indicator will illuminate and a single chime will sound when the object is first detected.
2. If the object is 0.6-1.0 m (2-3.3 ft) away from the vehicle, the amber outside and the amber middle indicators will illuminate.
3. If the object is 0.3-0.6 m (1-2 ft) away from the vehicle, the amber outside, amber middle, and red outside indicators will illuminate and the chime sounds continuously.
4. If the object is less than 0.3 m (1 ft) away from the vehicle, the amber outside, amber middle, and red outside indicators will flash and the chime sounds continuously.

If the rear parking assist system detects a malfunction, a DTC will be stored and the parking assist control module will send a serial data message to the instrument panel cluster to display the SERVICE PARK ASSIST message on the driver information center. The red LED on the parking assist indicator will be illuminated as a notification to the driver that a malfunction exists and the system is disabled.

Towbar Enabling

If the vehicle has a factory Trailer Hitch installed and the owner uses a factory ball mount package there is a personalization option available to allow the Rear Park Assist system to work with the factory Trailer Hitch.

This option can be selected using the Vehicle Personalization in the Radio and selecting Collision/Detection Systems. Press the MENU/SELECT knob when Park Assist is highlighted. Turn the knob to select Tow Bar. Press the knob to confirm and go back to the last menu.

Rear Parking Assist System Driver Information Center Messages

SERVICE PARK ASSIST

The driver information center also displays SERVICE PARK ASSIST when a loss of communication occurs with the parking assist control module.

PARK ASSIST OFF

The PARK ASSIST OFF message is displayed in the driver information center when the parking assist system is disabled due to conditions that disable or inhibit the system. The red LED in the park assist indicator will be illuminated. The parking assist control module requests the driver information center display PARK ASSIST OFF when it detects that one of the following conditions

1. The rear parking assist system is manually disabled by the vehicle operator through the audio system personalization menu.
2. An object is attached to the rear of the vehicle, such as a trailer, bicycle rack, trailer hitch receiver, or tow bar. Also, an object extending beyond a lowered tailgate will disable the system.
3. The parking assist sensors are covered by snow, mud, dirt, slush, or ice.
4. The vehicle bumper is damaged.
5. Excessive paint thickness on a replacement parking assist sensor.
6. The parking assist sensors are disrupted by vibrations, like those caused by a large nearby vehicle or from heavy equipment such as a jackhammer.

Object Detection Description and Operation (Front View Camera with UEU)

The forward collision alert system is a convenience feature of the front view camera that issues a warning to the driver when a potential collision risk exists. The front view camera is located behind the windshield, looking out at the road ahead and detecting vehicles directly ahead, within a distance of approximately 60 meters (197 ft). The forward collision alert system is always active and operates at speeds above 40 kph (25 mph). When the system detects a vehicle in the path ahead, the green vehicle ahead indicator in the vehicle direction display is illuminated. When approaching another vehicle too rapidly, the collision alert symbol will flash in the vehicle direction display. Simultaneously an audible alert sounds. Forward collision alert does not warn the driver of any objects that are not detected as a vehicle, like e.g. pedestrians, animals, signs, guard rails, bridges, construction barrels or other stationary or slow moving objects. The forward collision alert timing sensitivity to control the distance to the vehicle ahead can be set using the forward collision alert switch in the left steering wheel controls.

In some cases the camera may detect a vehicle that is not in the path ahead, or the system may occasionally provide unrealistic alerts. This could respond to a turning vehicle ahead, guard rails, traffic signs, or other stationary objects. This is normal operation, the vehicle does not need service. Forward collision alert may sometimes set unnecessary alerts to turning vehicles, vehicles in other lanes, objects that are not vehicles, or shadows. These alerts are normal operation and the vehicle does not need service.

The forward collision alert system is made up of the following components

1. Front view camera module
2. Forward collision alert switch
3. Instrument cluster/Vehicle direction display
4. Radio

Front View Camera Module

The camera detects vehicles in front of the host vehicle. The front view camera module requests the green vehicle ahead alert indicator in the vehicle direction display ON via serial data when the front view camera system has detected a vehicle in the driving path ahead. The front view camera module also communicates via serial data with the driver information center and the radio to request visual and audible alerts.

1. Lane departure warning system unavailable
2. Forward collision alert OFF
3. Service front camera

Forward Collision Alert Switch

The forward collision alert switch provides an input to the front view camera module to select the alert timing sensitivity when approaching another vehicle too rapidly. The front view camera module provides a signal voltage to the normally open switch. When the switch is pressed, the signal circuit is pulled to ground, indicating to the front view camera module that the system has been requested to change the alert timing sensitivity. The first button press shows the current alert timing setting on the driver information center. With every button press, the alert timing sensitivity is changed. The current alert timing setting will be maintained until it is changed. The preset alert timing setting is displayed in the top line of the driver information center. The position of the forward collision alert switch can vary with different vehicles. For the exact position please refer to the user's manual.

Instrument Cluster

The Vehicle direction display contains the green vehicle ahead indicator, which indicates to the driver that the Front View Camera system has detected a vehicle in the driving path ahead and is controlled via serial data. When approaching another vehicle too rapidly, the collision alert symbol will flash in the Vehicle direction display. The red Front collision alert display will stay continuously illuminated if the vehicle ahead remains much too close.

Radio

The radio controls the audible alert for the forward collision alert system. If the host vehicle is approaching another vehicle too rapidly, the radio will command an audible alert to the driver.

Forward Collision Alert System Driver Information Center Messages

The front view camera module can command the driver information center to display the various messages to alert the driver of a system concern or status information. For detailed information about the possible messages please refer to the user's manual.

Object Detection Description and Operation (Front View Camera with UFL)

The lane departure warning system is a convenience feature of the front view camera that issues a warning when the system detects that the vehicle has unintentionally crossed a lane marking. The front view camera is located behind the windshield, looking out at the road ahead and detecting any lane markings.

The lane departure warning system is made up of the following components

1. Front view camera module
2. Lane departure warning switch
3. Instrument cluster/Vehicle Direction Display
4. Radio

Front View Camera Module

The camera detects visual queues such as lane markings. When it is determined that the vehicle has unintentionally moved outside of the lane, a visual and audible warning is given to the driver. The front view camera module receives an input from the lane departure warning switch and controls the lane departure warning switch indicator output. The front view camera module also communicates via serial data with the instrument cluster and radio to request visual and audible alerts.

Lane Departure Warning Switch

The lane departure warning switch provides an input to the front view camera module to turn the lane departure warning system ON and OFF. The front view camera module provides a signal voltage to the normally open momentary switch. When the switch is pressed, the signal circuit is pulled to ground, indicating to the front view camera module that the system has been requested to turn ON or OFF. The lane departure warning switch also contains the lane departure warning switch indicator, which is controlled by the front view camera module to indicate the ON and OFF status of the lane departure warning system. When the system has been enabled by the lane departure warning switch, the front view camera module applies ground to the switch indicator and illuminates the LED. The location of the lane departure warning switch can vary with different vehicles. For the exact location please refer to the user's manual.

Instrument Cluster

The vehicle direction display contains green and amber lane departure warning indicators. These indicate to the driver the current status of the lane departure warning system and are controlled via serial data by the front view camera module. When the vehicle speed is above 56 km/h (35 MPH) and the system has detected the required lane markings and is ready to assist, the green indicator will be illuminated on the vehicle direction display. If the vehicle has unintentionally left the lane, the amber indicator will flash.

Radio

The radio controls the audible alert for the lane departure warning. If the vehicle has unintentionally left the lane, the radio will command three beeps as an audible alert to the driver.

Lane Departure Warning Operation

System operation can be describe by the following modes

1. Off State: The system has been turned off by the driver, using the lane departure warning switch. The lane departure warning indicator will not be illuminated.
2. Not Ready To Assist: The system is enabled and the lane departure warning indicator is illuminated, but not ready to assist when any of the following conditions is true: Vehicle speed is less than 56 km/h (35 MPH). The system is designed to function at speeds greater than 56 km/h (35 MPH). The system cannot detect lane markings. This may be because there are no lane markings, as on a country road or that the lane markings cannot be determined due to snow, rain, or other driving conditions. The windshield area in front of the camera or the camera lens is blocked by fog, dirt, damage to the windshield or other elements that may prevent the camera from detecting lane markings.
3. Ready To Assist: The system is enabled and ready to warn of the unintentional lane crossing. The system is ready to assist when the green lane departure warning indicator is illuminated on the vehicle direction display.

Lane Crossing Alerts

1. When one of the following conditions are met, the system will not give alerts: The correct turn signal is activated. An activated turn signal is interpreted as an intentional lane crossing. The operator makes an intentional steering maneuver. The operator makes an intentional accelerating maneuver. The operator makes an intentional braking maneuver.
2. Lane crossing alert consists of the following: Three chimes are activated through the radio. The amber lane departure warning indicator will flash.

Lane Departure Warning System Driver Information Center Messages

Rear Vision Camera System Operation

The rear vision camera system consists of a video camera located at the rear of the vehicle and the radio.

When the transmission is placed into REVERSE, a 12 volt signal is sent to the rear vision camera by the body control module (BCM). This signal indicates to the camera that the vehicle is in reverse and image display is requested. The rear vision camera receives ignition voltage and a constant ground to power the camera. Video signal + and video signal - circuits carry the video image from the rear vision camera to the radio. Additionally, the video signal circuits are shielded to prevent any interference which may lead to a loss of video signal resolution and a degraded video image. The shield is provided a ground path by the rear vision camera.

The following conditions may cause a degraded rear vision camera image

1. Ice, snow, or mud has built up on the rear vision camera
2. Dark conditions
3. Extreme light conditions, such as glare from the sun or the headlights of another vehicle
4. Damage to the rear of the vehicle
5. Extreme high temperatures or extreme temperature changes

If a malfunction is detected in the system, Service Rear Vision Camera may be displayed on the navigation radio as an indicator to the customer that a problem exists that requires service.
