History Codes

Upon entering the diagnostic mode, the MALL module provides audible feedback in the form of tones. The number of tones represents the stored history code number. The FASTEN BELTS indicator flashes with each tone. 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, one tone sounds for the FASTEN BELTS indicator circuit, followed by 2 tones 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.
