I/O Mode Feedback For Vehicles Equipped With Keyless Entry

Mall Modules Audible Feedback:




For vehicles with keyless entry, the MALL module electrical schematic differs from that of vehicles without keyless entry. For vehicles with keyless entry, the audible feedback is different when activating the power door lock switch, trans axle gear selector, and keyless entry unlock (using the keyless entry transmitter). The chart describes the feedback for this case.

Note that for Pontiac vehicles, no bongs occur when shifting into the PARK position due to the ignition-OFF door unlock feature.

MALL Input/Output:




The table lists the MALL inputs and outputs that should be evaluated during the Input/Output (I/O) mode.
