Active Codes

WARNING: This page is about a different car, the 1995 Dodge Ram Wagon and 1995 Dodge Ram Van. However, it is still accessible from the selected car via links, so may be relevant.

Active codes are hard codes and are accessed through DRB. If a malfunction is detected, AIR BAG warning light remains on until service is performed. Active fault codes are stored in ACM memory after ignition switch is cycled. Active fault messages automatically erase when fault is corrected.
