While in the Input/Output (I/0) mode, the technician may test each input to the MALL module by activating/deactivating its input device (for example, door latch switch, interior lamp switch, seat belt switch, etc.). The MALL module provides feedback on each input transition in the form of a single bong along with a simultaneous flash of the FASTEN BELTS indicator.
Test the battery protection (PBATT) Input/Output by cycling the interior lamps switch. For example, the first cycle (OFF, ON, OFF) deactivates the PBATT output (interior lamps OFF). Cycling the interior lamp switch once again activates the PBATT output (interior lamps ON). The cycle repeats afterwards.
