POWER DOOR LOCKS/RKE
*ALL DOORS FAILING TO UNLOCK FROM ANY SWITCH —
TEST
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 Unlock Relay Output (cavity 76)
circuit in the Unlock 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 Lock 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 Lock Relay.
No
Yes → Go To 7
7 Turn the ignition off.
Remove the Door Lock Relay from the Junction Block.
Measure the resistance between ground and the Ground circuit (cavity 84 in the Lock
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 Unlock Relay from the Junction Block.
Remove the Body Control Module from the Junction Block.
Measure the resistance of the Door Unlock Relay Control circuit between the Door
Unlock Relay connector cavity 80 and Junction Block Body Control Module connector
cavity 18.
Is the resistance below 1.0 ohm?
Yes → Go To 9
→ Replace the Junction Block.
No
