Diagnostic Test

  1. CHECK FOR AN ACTIVE DTC 
    NOTE:

    Diagnose any Can C or Can B failures before continuing.

    NOTE:

    An external Radio-Frequency Identification (RFID) key (and/or pass/radio key), such as one used to gain access to a 24 hour gym, can cause this DTC to set and create a no start condition. Inspect the customer's key chain for any type of RFID key. If one is not found, question the customer to see if a spare key chain has this RFID key on it or if it was removed from the original key chain before the vehicle was released for service. If a RFID key is present, remove the ignition key from the vehicle and remove the RFID key from the key chain.

    1. With the scan tool, read Powertrain Control Module (PCM) DTCs and Freeze Frame Data and record on the repair order.
    2. Using the recorded Freeze Frame Data and the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
    3. With the scan tool, read PCM DTCs.

      • Replace the Ignition Key.
      • Perform the RF HUB VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • If this DTC cannot be reset, it could have been an actual theft attempt or caused by Radio-Frequency interference. Check for the following, but not limited to:
        • An external Radio-Frequency Identification (RFID) key (and/or pass/radio key), such as one used to gain access to a 24 hour gym.
        • Aftermarket alarms or auto start systems
