DTC Descriptor
DTC B0968 00
- Parking Aid Indicator Circuit
Diagnostic Fault Information
Circuit/System Description
The rear object sensor control module directly controls the parking assist indicators located in the rear parking assist display. The rear object sensor
control module monitors the voltage supplied to the rear parking assist display to verify it is within operating range. The rear parking assist display
consists of two amber and one red LED that indicate the distance of an object from the rear bumper. As objects become progressively closer to the
bumper, the rear object sensor control module will illuminate the LEDs in a sequence: one amber LED, both amber LEDs, and lastly, both amber
LEDs and the red LED.
