Issue
Normal system Verify the system is functioning normally. Drivers who are unfamiliar with the system may
operation report they don't like the way it beeps or how it activates the brakes. Use sections STEPS TO
TROUBLESHOOTING, DIAGNOSTIC TROUBLE CODES and UNDERSTAND THE DRIVERS
COMPLAINT to verify if the system is functioning normally; then continue.
Trouble codes Some trouble codes indicate a temporary condition and will clear when that condition is no longer
caused by present. If these persist, further investigation is warranted. Proceed to the UNDERSTAND THE
temporary operating DRIVERS COMPLAINT section.
conditions
Sensor If the performance of the system seems to be erratic or unpredictable, the forward radar sensor
misalignment could be misaligned and may need to be aligned both vertically and laterally. If there is a trouble
code or if the system does not function, the sensor is severely misaligned and will not operate
until corrected.
Inspect the front of the vehicle. If it has been damaged or if the vehicle does not track straight,
both of these conditions must be repaired before troubleshooting Bendix
Sensor blocked If the system doesn't seem to work at all, the sensor is probably blocked. A trouble code will also
be set. Visually inspect it, clear the blockage, turn the ignition on and run through a power cycle.
Vehicle trouble Bendix
