During scan diagnosis, DTC B1882 (power liftgate position sensor 1 circuit) may be set.

Reprogramming with the latest software is required. The wi-TECH software level must be at release 13.03 or higher to perform the update. Chrysler recommends the update first before further diagnosis (if required).
