Diagnostic Aids

The following is a brief description of potential causes which may aid in diagnosis

1. Manual Disable - The parking assist system has been disabled through the parking assist switch or 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, or a bicycle rack may cause this concern. 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. Vehicle 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 large a truck 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.

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.

Note. Circuit/System Verification must be performed before Circuit/System Testing.

1. Ignition OFF, disconnect the harness connector at the rearview camera.
2. Test for less than 5 ohms between the ground circuit terminal 5 and ground.
3. If greater than the specified range, test the ground circuit for an open/high resistance.
4. Ignition ON, verify a test lamp illuminates between the ignition circuit terminal 6 and ground.
5. If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
6. Engine running, park brake applied, transmission in REVERSE, test for greater than 11 V between the control circuit terminal 3 and ground.
7. If less than the specified value, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 Body Control Module.
8. Ignition OFF, disconnect the X4 harness connector at the A11 Radio.
9. Ignition ON, test for less than 0.3 V between the following signal circuit terminals at the rearview camera harness connector and ground: Signal (+) circuit terminal 1 Signal (-) circuit terminal 4
10. If greater than the specified value, test the signal circuit for a short to voltage.
11. Test for infinite resistance between the following circuit terminals at the rearview camera harness connector and ground: Signal (+) circuit terminal 1 Signal (-) circuit terminal 4
12. If not the specified value, test the circuit for a short to ground.
13. Test for less than 5 ohms between the signal (+) circuit terminal 1 at the rearview camera harness connector and the signal (+) circuit terminal 5 X4 at the A11 Radio harness connector.
14. If greater then the specified value, test the signal circuit for an open circuit/high resistance.
15. Test for less than 5 ohms between the signal (-) circuit terminal 4 at the rearview camera harness connector and the signal (-) circuit terminal 15 X4 at the A11 Radio harness connector.
16. If greater then the specified value, test the signal circuit for an open circuit/high resistance.
17. If all circuits test normal, replace the rearview camera.
18. Engine running, transmission in REVERSE, verify a clear rear vision image is displayed on the radio.
19. If a clear rear vision image is not displayed, replace the A11 Radio.

1. The side object sensors are capable of detecting when they are blocked by mud, snow, or ice build up on the rear fascia. When a sensor is blocked, the driver information center will display SIDE BLIND ZONE SYSTEM UNAVAILABLE. The side blind zone alert system transitions back to the normal operating state when the blockage is removed. Bumper sticks, labels, and heavy rain storms may also cause this condition.
2. The side blind zone alert system is designed to ignore stationary objects; however, the system may occasionally detect guard rails, signs, trees, shrubs, or other stationary objects as an object in the blind zone. This is normal system operation and does not require service.
3. The side blind zone alert system may indicate an object in the blind zone if a trailer is attached to the vehicle, or a bicycle or object is extending out to either side of the vehicle.
4. The side blind zone alert system is disabled if any of the following occurs: There is a loss of serial data communication or a side blind zone alert system DTC is set. The side blind zone alert system is manually disabled by the driver through the radio.
5. Each side object sensor maintains a history buffer of the previous 16 side blind zone alert events which can be accessed using the scan tool. These parameters may be used to help diagnose a system malfunction or an intermittent concern.
6. Because the sensors are identical, they may be swapped from one side of the vehicle to the other in an attempt to isolate a concern. Sensors should NOT be swapped from one vehicle to another.

Certain factors will affect the operation of the lane departure warning system. When the system is operating properly, the green lane departure 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 indicator will not appear when the system is having difficulty seeing the lines on the road or if the view of the camera on the windshield 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.
