Power Door Lock Switch: Description and Operation
SYSTEM OPERATION
The power locks are controlled by a two-way switch mounted in a bezel on the trim panel of each front door. The switch controls the battery feeds
to the lock and unlock sense inputs of the high-line Central Timer Module (CTM).
The power lock switches cannot be repaired and, if faulty or damaged, the entire switch must be replaced.
CIRCUIT OPERATION
The door lock switches have two circuits that connect from the switches to the CTM. When the operator selects UNLOCK, from either switch,
circuit F35 is connected to circuit P36.
When the operator selects the LOCK, from either switch, voltage is passed through the CLOSED contacts in the switch to circuit P35.
The CTM then process this request and supplies power and ground to the appropriate circuits. When the LOCK function is selected power is
supplied on circuit P33 to all the motors. Ground is supplied on circuit P34. For the UNLOCK function the circuits are reversed.
