Power Locks: Description and Operation

SYSTEM OPERATION
Voltage is applied to the Power Door Lock Module through RH Circuit Breaker and the P/W Fuse at all times. The Power Door Lock Module controls the operation of the Power Door Locks by responding to switch inputs into the module.

LOCK OPERATION
The power door locks may be locked from either the Left or Right Door Lock Switch. When either Switch is pressed toward the "LOCK" position, a ground signal is sent to the Power Door Lock Module via circuit PB01 (GN/W). The Module then applies voltage to all door lock actuators via circuits PH35 (W/G) and PH31 (GN/Y). All door lock actuators operate. If the sliding door is open, it does not lock because the circuit is open at the Sliding Door Contact Switches. If the sliding door is closed after the Door Lock Switch was pressed, the module enters the sliding door lock delay mode. In this mode, the Module waits for the Sliding Door Ajar Switch to open, removing ground from circuit PB05 (BK/W). The Module then applies voltage to circuits PH35 (W/G) and PH31 (GN/Y) to lock the sliding door.

UNLOCK OPERATION
The power door locks may be unlocked from the Left Door Lock Actuator Assembly or either door lock switch. When either door lock switch is pressed toward the "UNLOCK" position, a ground signal is sent to the Power Door Lock Module via circuit PB02 (GN/O). The Module then applies voltage to all door lock actuators via circuits PH35 (W/G) and PH31 (GN/Y). All door lock actuators operate. When the key or the left interior lock knob is used to unlock the driver's door a ground signal is sent to the Power Door Lock Module via circuit PB04 (GN/R). The Module then applies voltage to all door lock actuators via circuit PH35 (W/G) and ground to PH31 (GN/Y) to lock all doors.
