For a complete wiring diagram, refer to the Wiring Information. Electrical Diagrams

- When Monitored:
During vehicle start up.

- Set Condition:
During the vehicle start up procedure, the module looks at the door handle circuits. If the sense or return circuits are open or shorted, for over two seconds, this code will set.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. Using the scan tool, record and erase the DTCs.
3. Start the vehicle and let run for 30 seconds.
4. Turn the engine off (ignition on).
5. Wait 30 seconds.
6. Using the scan tool, read the DTCs.

Does the scan tool display B259D-00-REAR RIGHT DOOR HANDLE SENSE?

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 the BODY VERIFICATION TEST. Body Verification Test.
