9K-2 Driver's Door Lock/Unlock Inoperative, Passenger Operative

CIRCUIT DESCRIPTION
Lock function: Battery voltage is applied through the door lock relay and CKT 295 to the driver's door lock actuator. The driver's door lock actuator is grounded through CKT 694 and Remote Control Door Lock Receiver (RCDLR). Unlock function: The RCDLR receiver applies voltage to the driver's door lock actuator through CKT 694. The driver's door lock actuator is grounded through CKT 295 and the door lock relay.

CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.
1. Operating the door lock switches will indicate if driver's door lock functions.
2. Check for unlock signal at the RCDLR.
3. Check for voltage on CKT 694. Voltage on CKT 694 would prevent the driver's door lock actuator from locking.
4. Check that the RCDLR grounds CKT 694 to enable a lock request.
5. Check for open in CKT 295 or CKT 694 to driver's door lock actuator.

DIAGNOSTIC AIDS
Program a known good transmitter (see procedure) and test the driver's door lock and unlock functions. If the driver's door lock and unlock functions operate normally, the original transmitter was defective. If the driver's door lock and unlock functions are still inoperative replace the RCDLR. If a known good transmitter will not program, refer to 9K-8. 9K-8 Remote Control Door Lock Receiver/Trans Will Not Program
