TEST
19 Turn the ignition off.
Remove the Door Lock Relay from the Junction Block.
Using a 12-volt test light connected to 12-volts, check the Ground circuit.(cavity 84)
in the relay connector.
Does the test light illuminate brightly?
Yes → Go To 20
→ Repair the Ground circuit for an open.
No
20 Remove the Door Lock Relay from the Junction Block.
Measure the resistance across terminals 85 (2) and 86 (1) of the Door Lock Relay.
Is the resistance between 50.0 and 90.0 ohms?
Yes → Go To 21
→ Replace the Door Lock Relay.
No
21 Remove the Door Lock Relay from the Junction Block.
Measure the resistance between terminals 86 (1) and 30 (3), 86 (1) and 87 (5), 86 (1)
and 87a (2) of the Door Lock Relay.
Is the resistance below 1000.0 ohms for any of the measurements?
Yes → Replace the Door Lock Relay.
→ Go To 22
No
22 Remove the Door Lock Relay and Door Unlock Relay from the Junction Block.
Measure the resistance across terminals 30 (3) and 87a (4) of each relay.
Is the resistance below 1.0 ohm in both relays?
→ Replace the Relays as necessary.
No
Yes → Go To 23
23 Remove the Door Lock Relay and Door Unlock Relay from the Junction Block.
Measure the resistance between the Lock Relay Output (cavity 81) in the Door Lock
Relay connector and the Unlock Relay Output (cavity 76) in the Door Unlock Relay
connector.
Is the resistance below 10.0 ohms?
→ Using the wiring diagram/schematic as a guide, repair the open
No
Yes → Test Complete.
24 Turn the ignition off.
Remove the Body Control Module from the Junction Block.
Measure the resistance of the Door Lock Relay Control circuit between the Door Lock
Relay connector cavity 85 and Junction Block Body Control Module connector cavity
15.
Is the resistance below 1.0 ohm?
Yes → Go To 25
→ Replace the Junction Block.
No
