B259B-00-FRONT RIGHT DOOR HANDLE SENSE





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

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

- Set Condition:
When the PEM senses an open on the Passive Handle Switch Sense or handle Ground circuit for over one (1) minute, this code will set. If the handle circuits are shorted it will stop communication between the handle and the PEM and may also set this code.
