Normal Operation
The vehicle security module (VSM) energizes the lock or unlock relays based upon input from the keyless entry keypad. The keyless entry keypad uses circuits 78 (LB/YE), 122 (YE) and 123 (RD) to send signals to the VSM by grounding the selected circuit through the keyless entry keypad on circuit 57 (BK). The VSM locks or unlocks the doors based on keyless entry keypad input.

DTC B2695 - is an on-demand DTC that sets if the VSM detects a short to ground on the keyless entry keypad switch A input circuit 78 (LB/YE).

DTC B2696 - is an on-demand DTC that sets if the VSM detects a short to ground on the keyless entry keypad switch B input circuit 122 (YE).

DTC B2697 - is an on-demand DTC that sets if the VSM detects a short to ground on the keyless entry keypad switch C input circuit 123 (RD).
