SERVICE
Misaligned parking aid sensors or various vehicle mountings can cause parking aid malfunctions. This TSB provides diagnosis tips related to parking aid
systems.
1. Verify that the coding within J446 - Parking Aid Control Module is valid for the equipment installed on the vehicle (ie: trailer hitch, tow bar, etc.).
2. Check the vehicle fault memory and proceed according to GFF.
^ If GFF identifies a problem with a specific sensor, proceed with the test plan.
^ If GFF does not identify a specific sensor, check MVBs in J446 - Parking Aid Control Module starting with MVBs for oscillation.
MVBs for internal sensor oscillation (if applicable) (acceptable values = 0.8 to 1.5ms). If the oscillation is not within specification, proceed to step
10.
