*DRIVER DOOR UNLOCK CONTROL CIRCUIT PERFORMANCE
For a complete wiring diagram Refer to Section 8W.
| Possible Causes |
| (P238) DRIVER DOOR UNLOCK DRIVER CIRCUIT SHORT TO GROUND |
| (P238) DRIVER DOOR UNLOCK DRIVER CIRCUIT SHORT TO VOLTAGE |
| (P238) DRIVER DOOR UNLOCK DRIVER CIRCUIT OPEN |
| (P33) DOOR LOCK DRIVER CIRCUIT SHORT TO THE (P238) DRIVER DOOR UNLOCK DRIVER CIRCUIT |
| INSTRUMENT CLUSTER |
1. (P238) DRIVER DOOR UNLOCK DRIVER CIRCUIT SHORT TO GROUND
Turn the ignition off.
Disconnect the Instrument Cluster C1 connector.
Measure the resistance between ground and the (P238) Driver Door Unlock Driver circuit in the Cluster C1 connector.
Is the resistance below 1,000.0 ohms?
Yes
- Repair the (P238) Driver Door Unlock Driver circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Go To 2
2. (P238) DRIVER DOOR UNLOCK DRIVER CIRCUIT SHORTED TO BATTERY
Turn the ignition on.
Measure the voltage between ground and the (P238) Driver Door Unlock Driver circuit in the Cluster C1 connector.
Is there any voltage present?
Yes
- Repair the (P238) Driver Door Unlock Driver circuit for a short to voltage.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Go To 3
3. (P238) DRIVER DOOR UNLOCK DRIVER CIRCUIT OPEN
Turn the ignition off.
Measure the resistance between the (P33) Door Lock Driver circuit and the (P238) Driver Door Unlock Driver circuit in the Cluster C1 connector.
Is the resistance above 4.5 ohms?
Yes
- Check and repair (if necessary) the (P33) Door Lock Driver or the (P238) Driver Door Unlock Driver circuit for an open. If the wiring is okay, replace the driver door latch.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Go To 4
4. (P33) DOOR LOCK DRIVER SHORTED TO THE (P238) DRIVER DOOR UNLOCK DRIVER CIRCUIT
Measure the resistance between the (P33) Door Lock Driver circuit and the (P238) Driver Door Unlock Driver circuit in the Cluster C1 connector.
Is the resistance below 2.0 ohms?
Yes
- Repair the (P33) Door Lock Driver for a short to the (P238) Driver Door Unlock Driver circuit.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
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)
