B259A-00-FRONT LEFT DOOR HANDLE SENSE







- When Monitored:
During the Passive Entry or Keyless Go event.

- Set Condition:
During the Passive Entry procedure and the FOBIK outside the car and within 6 feet from the handle, 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. Using the FOBIK, turn the ignition on.
2. Using the scan tool, record and erase the DTCs.
3. With the scan tool, select: PEM, More Options and System Tests.
4. Perform the PEM Door Handle Verification Tests.
5. With the scan tool, read the DTCs.

Does the scan tool display: B259A-00-FRONT LEFT DOOR HANDLE SENSE as active?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
