B1839

B1839-PASSENGER DOORS UNLOCK CONTROL CIRCUIT LOW- CLUSTER





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
Continuously

- Set Condition:
When the Cluster senses a low condition on the (P292) Passenger Doors Unlock Relay Control circuit for over 10 seconds, this code will set.





Theory of Operation

If the (P292) Door Unlock Relay Control circuit has been shorted to ground for any length of time, the door latch solenoids will probably be damaged. Check the door latches after the short is repaired.

Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase DTC's
Operate the door locks several times.
Cycle the ignition from on to off.
Turn the ignition on.
With the scan tool, read DTC's.
Does the scan tool display B1839-PASSENGER DOORS UNLOCK CONTROL CIRCUIT LOW?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. DOOR UNLOCK RELAY SHORTED




Turn the ignition off.
Remove the PDC fuse No. 19.
Disconnect the Cluster C2 connector.
Measure the resistance between ground and the (P292) Door Unlock Relay Control circuit in the Cluster C2 connector
Is the resistance below 10000.0 ohms?

No

- Replace the Instrument Cluster.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

Yes

- Go To 3

3. (P292) DOOR UNLOCK RELAY CONTROL CIRCUIT SHORT TO GROUND




Disconnect the Junction Block C2 connector (on top of junction block).
Measure the resistance between ground and the (P292) Door Unlock Relay Control circuit in the Cluster C2 connector.
Is the resistance below 10000.0 ohms?

Yes

- Repair the (P292) Door Unlock Relay Control circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Replace the Junction Block.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
