Retained Accessory Power (RAP) Malfunction

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach
* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview) provides an overview of each diagnostic category.



Circuit/System Description

Retained accessory power (RAP) permits the operation of some devices after the ignition switch is turned OFF. These selected items will remain in operation until any of the front passenger doors is opened or until the RAP function timer reaches its shut-off limit, which is 10 minutes. The instrument panel module (IPM) monitors the ignition mode signal from the ignition mode switch, battery condition and the front doors status to determine whether RAP should be initiated.

Circuit/System Verification

With a scan tool, open and close the driver and passenger door while observing the driver and passenger door open switch parameters. The parameter should cycle between open and closed.

If the parameters do not cycle between the indicated states, replace the IPM.



Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
