5 Remove all 3 power door lock relays (door lock, door unlock and driver door unlock)
from the Junction Block.
Measure the resistance between ground and the Lock Relay Output (cavity 81) circuit
in the Lock Relay connector..
Is the resistance below 1000.0 ohms (should be infinite)?
Yes → Replace the Junction Block.
→ Go To 6
No
6 Remove the Door Unlock Relay from the Junction Block.
Measure the resistance across terminals 30 (3) and 87a (4) of the relay.
Is the resistance below 1.0 ohm?
→ Replace the Door Unlock Relay.
No
Yes → Go To 7
7 Turn the ignition off.
Remove the Door Unlock Relay from the Junction Block.
Measure the resistance between ground and the Ground circuit (cavity 79 in the
Unlock Relay connector)..
Is the resistance below 5.0 ohm?
→ Replace the Junction Block.
No
Yes → Test Complete.
8 Turn the ignition off.
Remove the Door Lock Relay from the Junction Block.
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 9
→ Replace the Junction Block.
No
