Power Door Locks Inoperative - Deadbolt

POWER DOOR LOCKS INOPERATIVE - DEADBOLT

DIAGNOSTIC AIDS
Central Door Lock and Deadbolt functions are controlled by the rear integration module (RIM), the individual door modules and lock actuators, the driver door key lock cylinder, which is mounted in the driver door, and the key cylinder lock switch, which is contained within the driver door lock actuator. For more information on these components and features, refer to Power Door Locks Description and Operation.

TEST DESCRIPTION

Step 1 - Step 8:

Step 9 - Step 21:

The numbers below refer to the step numbers on the diagnostic table.
4. This step verifies that the keyless entry remote transmitter is functional for the test procedures that follow in steps 7 and 8. The remote transmitter must be used in place of the driver door key cylinder when it is the driver door deadbolt motor being tested in step 8.
8. This step determines if the deadbolt motor has failed. If it is a passenger door deadbolt being tested in this step, either the driver door key cylinder, or the keyless entry remote transmitter may be used to activate the deadbolt. However, if it is the driver door deadbolt being tested in this step, the driver door key cylinder cannot be used to activate the deadbolt because the lock actuator connector containing the key cylinder input circuit has been disconnected in step 7. Care must be taken when observing the test lamp and attempting to activate the deadbolt motor from either the remote transmitter, or the driver door key cylinder. If you are using the remote transmitter, press the transmitter lock button twice within 3 seconds. The test lamp should flash once. If you are using the driver door key cylinder, either turn the key to the lock position and hold it there for 3 seconds or longer or turn it to the lock position twice within 3 seconds. The test lamp should flash once. Repeating either of these activations, however, will not produce another flash of the test lamp until the door has been commanded to undeadbolt. For either method of activation, remember that the door must be commanded to undeadbolt between each deadbolt command in order for the test to be accurate. Failure to follow these guidelines may result in misdiagnosis and the unnecessary replacement of parts.
12. This step determines if it is the door module or a deadbolt motor control circuit that has failed.
