Normal Operation
The rear only parking aid system is enabled when the vehicle ignition is in RUN and transmission is in REVERSE. For a front and rear system the front and rear sensors will always be active when the transmission is in REVERSE with the vehicle ignition in RUN. When the transmission is in DRIVE the front sensors will be active if the vehicle speed is above 0 km/h and below 8 km/h (5 mph). If the vehicle is in DRIVE and is not moving, the front sensors will only be active for 5 seconds before being deactivated. The system can be disabled through the traction assist/parking aid disable switch located on the instrument panel. A 750 Hz variable warning tone is generated from a parking aid speaker. The parking aid speaker warning tone rate increases as the vehicle gets closer to an obstacle.
Possible Causes
- sensor alignment
- parking aid module
- circuit 1367 (WH/YE) open or short to ground
- circuit 239 (WH/OG) open, short to ground, or short to power
