History Codes
Upon entering the diagnostic mode, the MALL module provides audible feedback in the form of bongs; the number of bongs represents the stored history code number. The FASTEN BELTS indicator flashes with each bong. In the following chart, the history code is listed with the corresponding short circuit condition:Body Control Module Diagnostic Information:
The MALL module cycles through the stored history code(s) 3 times. For example, if a short condition occurs on the FASTEN BELTS indicator circuit and battery protection circuit, 1 bong sounds for the FASTEN BELTS indicator circuit, followed by 2 bongs for the battery protection circuit. A 2 second pause occurs before the history codes repeat. If no history codes exist, the MALL module immediately enters the input/output mode.
The history codes may be erased by holding down the power door unlock switch for 4 seconds.
