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.
Are there any Door Lock related DTC's?
No
- Go To 2
Yes
- Refer to the symptom list for problems relating to Power Door Locks
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
2. (P33) DOOR LOCK DRIVER CIRCUIT SHORT TO GROUND
Turn the ignition off.
Disconnect the Instrument Cluster C1 connector.
Measure the resistance between ground and the (P33) Door Lock Driver circuit in the Cluster C1 connector.
Is the resistance below 1,000.0 ohms?
Yes
- Repair the (P33) Door Lock 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 3
3. (P33) DOOR LOCK DRIVER CIRCUIT SHORTED TO BATTERY
Turn the ignition on.
Measure the voltage between ground and the (P33) Door Lock Driver circuit in the Cluster C1 connector.
Is there any voltage present?
Yes
- Repair the (P33) Door Lock 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 4
4. (P33) DOOR LOCK DRIVER SHORTED TO THE (P240) PASSENGER DOORS UNLOCK DRIVER CIRCUIT
Turn the ignition off.
Measure the resistance between the (P33) Door Lock Driver circuit and the (P240) Passenger Doors Unlock Driver circuit in the Cluster C1 connector.
Is the resistance below 1.0 ohm?
Yes
- Repair the (P33) Door Lock Driver for a short to the (P240) Passenger Doors Unlock Driver circuit.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
No
- Go To 5
5. (P33) DOOR LOCK DRIVER CIRCUIT OPEN
Measure the resistance between the (P33) Door Lock Driver circuit and the (P240) Passenger Doors Unlock Driver circuit in the Cluster C1 connector.
Is the resistance above 4.0 ohms?
Yes
- Repair the (P33) Door Lock Driver or the (P240) Passenger Doors Unlock Driver circuit for an open.
- 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)
