B1835-DRIVER DOOR UNLOCK CONTROL CIRCUIT LOW- CLUSTER
For a complete wiring diagram Refer to Section 8W.
- When Monitored:
Continuously
- Set Condition:
When the Cluster senses a low condition on the (P1) Driver Door Unlock Relay Control circuit for over 10 seconds, this code will set.
| Possible Causes |
| (P1) DRIVER DOOR UNLOCK RELAY CONTROL CIRCUIT SHORT TO GROUND |
| JUNCTION BLOCK |
| INSTRUMENT CLUSTER |
Theory of Operation
If the (P1) Driver Door Unlock Relay Control circuit has been shorted to ground for any length of time, the driver door latch solenoid will probably be damaged. Check the driver door latch after the short is repaired.
Diagnostic Test
1. TEST FOR INTERMITTENT CONDITIONWith 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 B1835–DRIVER DOOR 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. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
2. DRIVER DOOR UNLOCK RELAY SHORTED
Turn the ignition off.
Remove the PDC fuse No.13.
Disconnect the Cluster C2 connector.
Measure the resistance between ground and the (P1) Driver Door Unlock Relay Control circuit in the Cluster C2 connector
Is the resistance below 1000.0 ohms?
No
- Replace the Instrument Cluster in accordance with service information.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
Yes
- Go To 3
3. (P1) DRIVER 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 (P1) Driver Door Unlock Relay Control circuit in the Cluster C2 connector.
Is the resistance below 1000.0 ohms?
Yes
- Repair the (P1) Driver Door Unlock Relay Control circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Replace the Junction Block in accordance with service information.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
