Blind Spot Monitor System
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbags, airbag curtains, knee blocker, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect the Intelligent Battery Sensor (IBS)/negative battery cable assembly from the negative battery post, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.
The following textual messages related to the Blind Spot Monitor (BSM) system may appear within the Electronic Vehicle Information Center (EVIC) display of the Instrument Panel Cluster (IPC):
- BLIND SPOT SYSTEM OFF - This message to the vehicle operator when the ignition first transitions to the ON status indicates that the BSM system has been turned off using the Setup Menu of the Radio Receiver Module (RRM).
- SERVICE BLIND SPOT SYSTEM - This message to the vehicle operator while the ignition status is ON indicates that the BSM system is unavailable due to a monitored system fault or faults.
- BLIND SPOT SYSTEM TEMPORARILY UNAVAILABLE
- This message to the vehicle operator while the ignition status is ON indicates that the BSM system is temporarily unavailable as a result of one of the following:
- Sensor Blockage - The amber BSM visual icon in both outside rear view mirrors will be illuminated as long as blockage exists or until the ignition status transitions to OFF, whichever occurs first.
- Monitored System Fault - The BSM system has detected a monitored system fault condition and has stored a Diagnostic Trouble Code (DTC). The amber BSM visual icon will be illuminated in both outside rear view mirrors for as long as the condition exists or until the ignition status transitions to OFF, whichever occurs first.
If the BLIND SPOT SYSTEM TEMPORARILY UNAVAILABLE message is received for a minimum of five minutes, please verify that the outboard area at each end of the rear fascia behind the rear wheel openings where the radar sensors are located is not blocked by snow, ice or road debris. If the area is blocked, remove the blockage. Full system functionality should be restored after about two minutes of driving. Then verify that the message is no longer present in the IPC display.
If the vehicle has experienced any trauma in the outboard area at each end of the rear fascia behind the rear wheel openings where the sensors are located, even if the fascia is not damaged, the radar sensor may have become misaligned. A misaligned radar sensor will result in the BSM system not operating properly.
