BLIND SPOT MONITOR SYSTEM

The Blind Spot Monitor (BSM) system is an available factory-installed electronic driving aid. This system provides both blind spot and Rear Cross Path (RCP) monitoring features. While the vehicle is being driven, this system alerts the vehicle operator when it detects other highway licensable vehicles that enter the targeted blind spot and cross path alert zones. These zones lie immediately to the right and behind as well as immediately to the left and behind the vehicle. Due to the surrounding rear vehicle structure or other adjacent stationary obstacles outside of the vehicle, these zones might be more difficult for the vehicle operator to easily monitor.

When the BSM system detects another vehicle within one of the target zones, the system is capable of illuminating an amber triangle icon located in each outside rear view mirror glass, as well as reducing audio system volume and sounding chime tones through the audio system speakers to provide the vehicle operator with both visual and audible alerts. However, it should be noted that this BSM system is intended to supplement and not to replace safe vehicle operating habits, including proper adjustment and use of the standard equipment inside and outside rear view mirrors.

The BSM system includes the following major components, which are described in further detail elsewhere within this service information

1. Blind Spot Displays - Vehicles equipped with the BSM system have an amber Light Emitting Diode (LED) unit mounted on the back of each outside rear view mirror glass case behind the translucent outline of a triangle in the mirror glass. The BSM system illuminates the appropriate triangle icon in amber each time a vehicle is detected in one of the blind spot or rear cross path alert zones.
2. Blind Spot Sensors - Vehicles equipped with the BSM system have both a Left Blind Spot Sensor (LBSS) and a Right Blind Spot Sensor (RBSS). The LBSS and the RBSS each include a RAdio Detection And Ranging (RADAR) sensor and an integral electronic control unit. Each of the two control units is independent, communicates on the Controller Area Network (CAN) data bus and is hard wired to its respective right or left blind spot display. The LBSS and the RBSS are concealed behind their respective right and left outboard ends of the rear bumper fascia, just behind each rear wheel opening.
3. Electronic Vehicle Information Center - In vehicles equipped with the optional BSM system, the Electronic Vehicle Information Center (EVIC) within the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC) may display textual warnings and error messages related to the current operating status of the BSM system.
4. Radio Receiver Module - The virtual buttons in the touch screen of the optional premium Radio Receiver Module (RRM) (also known as the radio or the head unit) provide an interface that allows the vehicle operator to enable, disable and modify certain BSM system settings using the customer programmable features option.

Hard wired circuitry connects the BSM system components to each other through the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other and to the vehicle electrical system through the use of a combination of soldered splices, splice block connectors and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin out and location views for the various wire harness connectors, splices and grounds.

The blind spot monitor system components cannot be adjusted or repaired. If any of the BSM system components are damaged or ineffective, that component must be replaced.

CHIME WARNING SYSTEM

A chime warning system is standard factory-installed equipment. The chime warning system uses an electromechanical transducer and an electromechanical relay that are soldered onto the electronic circuit board within the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC) to provide audible indications of various vehicle conditions that may require the attention of the vehicle operator or occupants.

The electromechanical transducer generates beep tones and chime tones, while the electromechanical relay generates click tones to emulate the sounds associated with conventional turn signal and hazard warning flasher operation. The microprocessor-based IC utilizes electronic chime request messages received from other modules in the vehicle over the Controller Area Network (CAN) data bus along with hard wired inputs to monitor many sensors and switches throughout the vehicle. In response to those inputs, the circuitry and programming of the IC allow it to control the audible outputs that are produced through its on-board transducer and relay.

The IC is capable of producing the following audible outputs

1. Slow Rate Repetitive Click - Repeated click tones that are issued at a slow rate of about 90 clicks per minute.
2. Fast Rate Repetitive Click - Repeated click tones that are issued at a fast rate of more than about 180 clicks per minute.
3. Single Chime Tone - A single beep or chime tone.
4. Slow Rate Repetitive Chime Tones - Repeated chime tones that are issued at a rate of about 50 chimes per minute.
5. Fast Rate Repetitive Chime Tones - Repeated chime tones that are issued at a rate of about 180 chimes per minute.

Hard wired circuitry connects the IC and the various chime warning system switch and sensor inputs to their modules and to each other through the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the IC through the use of a combination of soldered splices, splice block connectors and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin out and location views for the various wire harness connectors, splices and grounds.

The IC chime warning system circuits and components cannot be adjusted or repaired. If the IC circuitry, the on-board transducer or the relay are damaged or ineffective, the IC assembly must be replaced.

PARK ASSIST SYSTEM

A park assist system is an optional factory-installed electronic parking aid. During parking and other similar vehicle maneuvers this system alerts the vehicle operator to obstacles located in the path immediately behind the vehicle which, due to the surrounding rear vehicle structure, might be otherwise difficult to perceive. When an object is detected, the system uses graphics and chimes to provide the vehicle operator with visual and audible indications of the presence and proximity of such objects.

The park assist system includes the following major components, which are described in further detail elsewhere in this service information

1. Body Control Module - The Body Control Module (BCM) serves as the gateway between the Controller Area Network (CAN) data bus CAN C and CAN Interior High Speed (IHS) networks used to communicate between the Park Assist Module (PAM), the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC) and the Radio Receiver Module (RRM).
2. Instrument Cluster - In vehicles equipped with the optional park assist system, the Electronic Vehicle Information Center (EVIC) within the IC displays vehicle graphics and amber or red arc sections that illustrate the approximate location of obstacles within the rear path of the vehicle. The EVIC also displays textual warnings and error messages along with issuing audible alerts related to the current operating status of the park assist system. In addition, the EVIC provides an interface that allows the vehicle operator to manually disable or enable the park assist system using the customer programmable features option.
3. Park Assist Module - Vehicles equipped with the park assist system include a Park Assist Module (PAM) (also known as the ParkTronic System/PTS module), which is secured through integral mounting tabs by push-in type fasteners to the floor panel rear cross member directly below the right tail lamp pocket where it is concealed beneath the right side trim within the trunk area of the vehicle.
4. Park Assist Sensors - Vehicles equipped with the park assist system have four ultrasonic park assist sensors that are concealed behind the rear bumper fascia. Only the sensor membrane is visible on the outer surface of the rear bumper fascia. Each sensor is snapped into an individual molded plastic mounting bracket located at horizontal intervals along the back side of the rear bumper fascia.
5. Radio Receiver Module - In vehicles equipped with the park assist system, the PAM sends electronic message requests to the RRM to generate audible signals indicating the approximate distance of obstacles from the rear path of the vehicle. The RRM is capable of generating repetitive single chime tones at several varying frequencies or continuous tones through the rear audio system speakers. If the audio system speakers are already in use, the RRM will mute that output during chime tone generation.

Hard wired circuitry connects the various park assist system components to each other through the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other and to the vehicle electrical system through the use of a combination of soldered splices, splice block connectors and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention as well as pin out and location views for the various wire harness connectors, splices and grounds.

The park assist system components cannot be adjusted or repaired. If any of the park assist system components is damaged or ineffective, that component must be replaced.

The primary components of the Blind Spot Monitor (BSM) system are the microcontroller based Electronic Control Units (ECU) integral to each of the two RAdio Detection And Ranging (RADAR) sensors, one behind each outboard side of the rear bumper fascia. Each ECU operates on battery current received from a fuse in the interior Power Distribution Center (PDC) whenever the status of the ignition switch is ON, and the ECU has a path to ground at all times through a take out and eyelet terminal of the body wire harness that is secured to the body sheet metal. Each of these ECU communicate with each other as well as with other electronic modules in the vehicle over the Controller Area Network (CAN) data bus network.

The BSM system ECU continually monitor all of the BSM system circuits and components for readiness, and will store a Diagnostic Trouble Code (DTC) for any fault that is detected. The ECU also communicate with a diagnostic scan tool over the CAN data bus. When a BSM system ECU stores a DTC, it sends an electronic request message to the Electronic Vehicle Information Center (EVIC) in the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC) and a SERVICE BLIND SPOT SYSTEM or BLIND SPOT SYSTEM TEMPORARILY UNAVAILABLE textual message is displayed by the EVIC to alert the vehicle operator.

The BSM system ECU also monitor electronic messages received over the CAN data bus from the Radio Receiver Module (RRM) (also known as the radio or the head unit) indicating the customer programmable features settings for the BSM system. The BSM system ECU receive and analyze data inputs directly from the radar sensors, calculate and provide the proper hard wired outputs to illuminate the visual alert displays in their respective right or left outside rear view mirrors, as well as calculate and communicate the proper audible alert output requests to the RRM over the CAN data bus.

The BSM radar sensors allow the BSM system ECU to locate and identify nearby objects of interest meeting the criteria established by algorithms within the system software. The BSM displays provide the vehicle operator with a visual alert indicating that an object of interest has been detected within one of the vehicle detection zones. The BSM audible alerts are then issued by the RRM through the appropriate audio system speakers based upon electronic audible alert request messages received from the BSM system ECU. The BSM system ECU also send electronic radio mute request messages over the CAN data bus to the RRM whenever an audible alert is requested. This message activates the radio mute function while the audible alert is being sounded, then resumes normal radio function when the alert is completed.

The hard wired circuits between components related to the BSM system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the BSM system or the electronic controls and communication between ECU and other devices that provide some features of this system. The most reliable, efficient and accurate means to diagnose the BSM system or the ECU and communication related to BSM system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

BLIND SPOT MONITOR MODE

Unless disabled in the customer programmable features settings received through the Radio Receiver Module (RRM) (also known as the radio or the head unit), the Blind Spot Monitor (BSM) mode is active only when the manual transmission gear selector is in a position other than Reverse ( R ) or the automatic transmission gear selector is in a position other than Reverse ( R ) or Park ( P ). The BSM mode is intended to provide a visual alert to the driver when a target vehicle (object of interest) is located in the lane adjacent to and just behind either outside rear view mirror (the detection zone), in the blind spot area where vision of target vehicles may be inhibited by the rear structure of the host vehicle. If a turn signal is activated in the host vehicle in the same direction as that in which the target vehicle is located, an audible alert tone will also be generated. The audible alerts of the BSM mode are not active unless the turn signal is activated.

The width of the BSM mode detection zone covers one traffic lane over on each side of the host vehicle, approximately 4.0 meters (13 feet). The length of the BSM mode detection zone starts at the outside rear view mirror and extends approximately 4.5 meters (15 feet) rearward from the rear edge of the rear fascia. The BSM mode visual alerts are activated immediately if an object of interest is within the detection zone and meets the warning criteria. However, the BSM system will not activate these alerts if

1. The object of interest (target vehicle) comes from the rear of the detection zone and passes the host vehicle at a speed greater that 50 kilometers-per-hour (31 miles-per-hour).
2. The object of interest (target vehicle) enters the detection zone from the front and remains in the zone for less than 1.5 seconds.
3. The object of interest (target vehicle) passes through the detection zone with a relative speed greater than 20 kilometers-per-hour (12 miles-per-hour).
4. The object of interest (target vehicle) passes the host vehicle from the opposite direction.

The BSM mode audible alert may be deactivated if the operator prefers using the customer programmable features settings within the RRM. The BSM mode can be configured for visual and audible alerts, visual alerts only or for the entire BSM system (including Rear Cross Path/RCP mode) to be turned Off.

REAR CROSS PATH MODE

Unless disabled in the customer programmable features settings received through the Radio Receiver Module (RRM) (also known as the radio or the head unit), the Blind Spot Monitor (BSM) system provides a feature called Rear Cross Path (RCP) mode. The RCP mode is active only when the transmission gear selector (manual or automatic) is in the Reverse ( R ) position. The RCP mode is intended to aid the driver when backing out of parking spaces where vision of vehicles crossing laterally through the rear path of the host vehicle may be blocked. The host vehicle must proceed slowly and cautiously out of the parking space until the rear end of the vehicle is exposed. The BSM radar sensors will then have a clear view of the crossing traffic and, if an oncoming vehicle (object of interest) is detected, will generate visual and audible alerts to the operator of the host vehicle.

The BSM system monitors the rear detection zones on both sides of the vehicle for objects that are moving toward the side of the vehicle with speeds of from 1 to 3 kilometers-per-hour (1 to 2 miles-per-hour) up to 35 kilometers-per-hour (22 miles-per-hour), such as typically encountered in parking lot situations. In vehicles equipped with the BSM option, the RCP mode is enabled from the factory as a default. The RCP mode can be manually disabled and enabled by the vehicle operator using the customer programmable features option of the RRM.

The RCP mode normally uses the same BSM system customer programmable features settings. However, the RCP mode will always include the audible alert feature, even if it was disabled for the BSM mode using the RRM customer programmable features settings. The audible alert can not be deactivated for the RCP mode. The RCP mode visual alert is illuminated only in the display located on the same side of the vehicle where the object of interest is detected. Likewise, the RCP mode repeating short audible alert is issued only through the audio system speakers located on the same side of the vehicle where the object of interest is detected.

STANDBY MODE

The Blind Spot Monitor (BSM) system remains in standby mode as long as the park brake is applied in a vehicle with a manual transmission, or while the automatic transmission gear selector lever is in the Park ( P ) position. In the standby mode the system receives vehicle information, responds to changes in customer programmable features settings received through the Radio Receiver Module (RRM) (also known as the radio or the head unit) and can perform limited self-diagnostics indicating hard system fault conditions.

The chime warning system operates on battery current received from the Body Control Module (BCM) on a non-switched fused B(+) circuit so that the system may operate regardless of the ignition switch status. The chime warning system also monitors the ignition switch status so that some chime features are functional only when the ignition switch status is ON, while other features are functional regardless of the ignition switch status.

In nearly every instance the chime warning system simply provides an audible output to support a visual indication provided by a gauge or an indicator in the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC), or a textual message displayed by the Electronic Vehicle Information Center (EVIC).

This reminder indicates that a turn signal has been active continuously for 1.6 kilometers (1 mile) with the vehicle moving. The hazard warning flashers will not activate this chime feature.
59. Vehicle Not In Park Warning - The IC transducer will generate one short chime when the VEHICLE NOT IN PARK textual message is displayed in the EVIC. This warning indicates that the PARK position of the transmission is not engaged.
60. Vehicle Speed Is Too High To Shift Warning - The IC transducer will generate one short chime when the VEHICLE SPEED IS TOO HIGH TO SHIFT textual message is displayed in the EVIC. This warning is applicable only to vehicles equipped with the optional Dry Dual Clutch Transmission (DDCT).
61. Washer Fluid Low Warning - The IC transducer will generate one short chime when the WASHER FLUID LOW textual message is displayed in the EVIC. This warning indicates that the fluid level in the windshield washer reservoir is low. This chime will only occur once during any ignition cycle.

The IC provides chime service for all available features in the chime warning system, except for the audible warning function provided by the Radio Receiver Module (RRM) for the optional park assist system. The IC relies upon its internal programming, numerous hard wired inputs and electronic message inputs received from other electronic modules over the Controller Area Network (CAN) data bus to provide the chime warning system features. The programming of the IC determines the priority of each chime request input that is received, as well as the rate and duration of each chime that is to be generated.

The hard wired circuits between components related to the chime warning system may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the chime warning system or the electronic controls and communication between modules and other devices that provide some features of the chime warning system. The most reliable, efficient and accurate means to diagnose the chime warning system or the electronic controls and communication related to chime warning system operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

The park assist system is active only when the status of the ignition switch is ON, the parking brake is released, the transmission gear selector lever is in the REVERSE position and the vehicle speed is less than 16 kilometers-per-hour (10 miles-per-hour). In vehicles equipped with this option, the system is enabled from the factory as a default. The system can be manually disabled and enabled by the vehicle operator using the settings menu of the Electronic Vehicle Information Center (EVIC) and the push buttons of the EVIC switch pod in the left horizontal spoke of the steering wheel. If the vehicle operator does not want the system active, selecting the PARK ASSIST OFF setting of the EVIC will disable the system until the EVIC park assist setting is changed to PARK ASSIST ON .

Reasons for disabling the system include trailer towing and off road use. With a trailer attached to the vehicle the audible and visible park assist alerts would be incessant whenever the gear selector lever was in the REVERSE position due to the proximity of the trailer to the rear of the vehicle. Similarly, operating the vehicle off road may cause the park assist alerts to become distracting due to the proximity of large trees or boulders and the extreme rear approach angles that may be encountered while maneuvering on off road trails or terrain.

When the system is disabled, a PARK ASSIST SYSTEM OFF graphic and textual message will appear in the EVIC display of the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC) whenever the gear selector lever is in the REVERSE position. When the system is enabled, a PARK ASSIST SYSTEM ON graphic and textual message will appear in the EVIC display of the IC, and a PARK ASSIST READY graphic and textual message will appear in the display whenever the gear selector lever is in the REVERSE position.

The microprocessor based Park Assist Module (PAM) (also known as the ParkTronic System/PTS module) is the central component of the park assist system. It supplies voltage to the park assist sensors, receives and analyzes data from the sensors, calculates and communicates the proper display information to the EVIC display, calculates and communicates the proper audible outputs to the Radio Receiver Module (RRM), performs system diagnostics and communicates with other electronic modules in the vehicle or with a diagnostic scan tool over the Controller Area Network (CAN) data bus. The PAM operates on battery voltage received through a fuse in the Junction Block (JB) (also known as the interior Power Distribution Center/PDC) and is grounded through a take out of the body wire harness secured to the body sheet metal.

Four ultrasonic park assist sensors in the rear bumper fascia allow the park assist system to locate and identify the proximity of nearby obstacles. These sensors each generate ultrasonic sound pulses when triggered by the PAM, then signal the PAM when an echo of the reflected sound pulses is received. The detection distance range from the rear of the vehicle is about 2 meters (80 inches), and the detection height range from the ground is about 0.2 meters (7.8 inches) to about 0.8 meters (31 inches). The detection area extends somewhat around both rear sides (corners) of the vehicle.

The EVIC display unit provides the vehicle operator with a graphical representation of the vehicle along with numerous illuminated arc sections that indicate the relative location and range of detected objects. The display is visible directly in front of the vehicle operator and operates based upon the electronic message inputs received from the PAM over the CAN data bus. There are three regions at the rear of the vehicle designated for arc alerts: Center, Left and Right. The Center region consists of six zones, while the Right and Left regions consist of two zones. The zones range from furthest to nearest from the rear of the vehicle. The arc sections are illuminated in an amber color until the nearest zone is reached, at which point the arc sections become illuminated red in color.

Meanwhile, the RRM generates audible indications of a detected object by emitting a series of chime tones that grow progressively higher in frequency as the vehicle gets closer to the object. As the vehicle comes within about 35 centimeters (14 inches) of the object, the audible warning changes from a high frequency series of chime tones to a single continuous tone. If the audio system is active when the RRM receives a chime request message from the PAM, the audio output will be muted automatically while the park assist audible warnings are being generated.

When the PAM monitors a problem in any of the park assist system circuits or components, it stores a fault code or Diagnostic Trouble Code (DTC) in its memory circuit, sends an electronic message to the EVIC and the EVIC displays a graphic with a SERVICE PARK ASSIST SYSTEM textual message. If the PAM detects that the park assist sensors are inoperative due to an accumulation of road film, mud, ice or snow on the rear fascia, the EVIC will display a WIPE OFF REAR PARK ASSIST SENSORS graphic and textual message. When the system is disabled by the PAM, a PARK ASSIST SYSTEM DISABLED graphic and textual message will appear in the EVIC display of the IC whenever the gear selector lever is in the REVERSE position.
