While in Input/Output mode, each input to MALL module can be tested by activating/deactivating input device (door lock switch, seat belt switch, etc.). Each input transition is acknowledged with a single bong with a simultaneous flash of FASTEN BELTS indicator. See MALL INPUTS/OUTPUTS table for inputs and outputs that should be checked.
