Perform one of the following steps in order to lock or unlock a door:

The reversible actuators control the power door locks. The power door electrical system controls the actuators by applying battery voltage to 1 terminal and ground to the other terminal. The body control module (MALL) supplies this battery voltage and ground when the module receives a door lock or unlock signal. Normally, the MALL module connector C1 terminals A and C are both at ground. The MALL module control at connector C1 terminal C switches to battery voltage in order to lock the doors. The module provides battery voltage to all of the actuators on CKT 295 (GRY). The opposite side of each actuator is connected to the MALL module connector C1 terminal A. The MALL module connector C1 terminal A is still at ground. This grounded circuit path is CKT 694 (TAN) for the left front door lock actuator. The following components are the grounded circuit path:

CKT 294 (TAN) is the grounded circuit path for the other 3 door lock actuators. The actuator in each door runs in order to move the door locks to the LOCK position. In order to unlock the doors, the MALL module accomplishes the unlock function in the same way. However, the remote function actuator (RFA) controlled left front door lock isolation relay in this circuit allows for the following 2 methods of unlocking:

Pressing the UNLOCK button on the keyless entry transmitter provides an unlock signal to both the RFA and MALL modules. The RFA module turns on the output at terminal E6. This condition grounds CKT 1391 (LT GRN). The coil of the left front door lock isolation relay energizes. This condition opens the normally-closed relay contacts. This action disables the door lock circuit to the right front door lock and the rear door locks. Simultaneously, the MALL module provides battery voltage on CKT 694 (TAN) to the left front door lock actuator while holding CKT 295 (GRY) at ground. The left front door unlocks.

When the UNLOCK button is pressed a second time (within 5 seconds of the first press), the RFA module turns off the output at terminal E6. This condition removes ground from CKT 1391 (LT GRN). This condition also de-energizes the isolation relay. The relay contacts close, connecting CKT 694 (TAN) to CKT 294 (TAN). This action provides battery voltage to the rest of the door lock actuators on CKT 294 (TAN) while CKT 295 (GRY) is still held at ground. The rest of the doors unlock.

The door lock actuators are usually powered for just a moment. If the actuators remain on, an electronic circuit breaker in each actuator opens in order to protect against damage. Each circuit breaker has a positive temperature coefficient device which resets automatically when voltage is removed from the actuator.

In order to initiate door locking or unlocking, the body control module (MALL) receives an input signal at the following 2 terminals on connector C2:

The following circuits are common to both the keyless entry system and to the switches on the front doors:

Moving a door lock/window switch to the UNLOCK position connects CKT 781 (ORN/BLK) through the switch to ground CKT 151 (BLK/WHT). CKT 781 (ORN/BLK) grounds the body control module (MALL) connector C2 terminal C6 in order to provide the door unlock input signal.

Pressing the door unlock button on the keyless entry transmitter causes the remote function actuator (RFA) module to ground terminal E5. With this action the RFA module grounds CKT 781 (ORN/BLK). In turn, CKT 781 (ORN/BLK) grounds the MALL module connector C2 terminal C6 in order to provide the door unlock input signal.

Moving a door lock/window switch to the LOCK position connects CKT 780 (RED/BLK) through the switch to ground CKT 151 (BLK/WHT). CKT 780 (RED/BLK) grounds the remote function actuator (RFA) module at terminal E13 in order to provide the door lock input signal to the RFA module. The RFA module in turn grounds the control signal at terminal E4. This condition pulls CKT 195 (LT BLU) to ground. This action grounds the body control module (MALL) connector C2 terminal C7 in order to provide the door lock input signal. CKT 195 (LT BLU) is also the input circuit for the keyless entry unlock function. Pressing the door lock button on the keyless entry transmitter causes the RFA module to ground terminal E4. With this action the RFA module grounds CKT 195 (LT BLU). In turn, this action grounds the MALL module connector C2 terminal C7 in order to provide the door lock input signal.

The automatic door lock function is controlled by the remote function actuator (RFA) module. The RFA module receives a signal from the park/neutral position switch indicating whether the gear selector is in PARK or not. The RFA module provides a signal to the body control module (MALL) in order to lock the doors under the following conditions:

If programmed to do so, the RFA module also unlocks the doors when the gear selector is put back into PARK.

Program the ADL feature using the following 4 different lock and unlock modes:

Perform the following operations:

1. Turn ON the ignition.
2. Place the vehicle in PARK.
3. Close all of the doors.
4. Press and hold the door lock switch in the LOCK position.

While holding the door lock switch, press the LOCK button on the vehicle's transmitter. After the initial activation of the transmitter LOCK button, each additional activation will increment the ADL mode 1, from the current ADL mode. If cycled beyond ADL Mode 3, the RFA module will enter MODE 0. During this customization procedure, the Automatic Door Lock and Unlock will provide the customer with feedback of the current ADL mode. When the door lock switch is released, the RFA module will remain the recent ADL mode. Since Mode 0 has no ADL functions, no feedback occurs. If the ignition voltage is lost or if any door is opened while in the customization procedure, the following actions will occur:

The delayed locking feature allows the driver to delay the locking of the vehicle after the lock switch has been activated.

Upon activating the lock switch with the driver's door open, a chime sounds in order to let the driver know that the delayed locking mode is activated. After all of the doors have been closed for 5 seconds, the doors will lock automatically. After all of the doors have been closed for 5 seconds, the doors will lock automatically. If you open any door before the 5 seconds have elapsed, the timer will reset when all of the doors are closed. You may program this feature ON or OFF for each transmitter.

You must enable the delayed locking feature with the scan tool in order to have access to this feature. The RFA module software for the delayed locking feature is turned OFF on all new vehicles and service replacement parts. Use the following procedure in order to perform initial activation of delayed locking:

1. Connect the scan tool.
