Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR AN INTERMITTENT CONDITION 
    1. Turn the ignition on.
    2. With the scan tool, record and erase the WIN DTCs.
    3. Cycle the ignition switch from on to off, wait five seconds and then back to on.
    4. With the scan tool, read the active WIN DTCs.
      NOTE:

      This DTC identifies two fault conditions together, an unknown or non communicating FOBIK and a negative response from the PCM to start the engine. First, root cause why the FOBIK is unknown or not responsive. Once the FOBIK issue is corrected, the B1A29 DTC should go to a stored status. Once the B1A29 becomes stored, the B1A28 DTC can be corrected.

      Does the scan tool display: B1A29-SKIM BASESTATION MISMATCH as Active?

      Yes 

      • Go To  2.

      No 

      • Verify the FOBIK in use is the FOBIK that caused this DTC to set. If it was, perform the WIN INTERMITTENT TEST. Refer to Standard Procedure .
  2. VERIFY FOBIK COMMUNICATION 
    NOTE:

    When diagnosing any WIN concern, all FOBIKs should be present

    1. With the scan tool, read the WIN active DTCs again.

      Does the scan tool display; B1A35-UNIDENTIFIED KEY COMMUNICATION ERROR as Active?

      Yes 

      • Go To  3.

      No 

      • Go To  4.
  3. TEST LF COMMUNICATION 
    1. With the scan tool, in the WIN menu, go to Data Display, Bussed Outputs and check the "SKREEM Status" for the current FOBIK that is being used. Record that status.
    2. Remove the FOBIK.
    3. Insert one of the other known good FOBIKs used with this vehicle.
      NOTE:

      If another FOBIK is not available, insert a new unprogrammed FOBIK to test the WIN module's low frequency (LF) communication (do not program the FOBIK).

    4. Check the "SKREEM Status" for the current FOBIK. Verify that the status changed from the first FOBIK that was in the ignition.

      Did the "SKREEM Status" change?

      Yes 

      • Replace and program the FOBIK in accordance with the Service Information.
      • Perform the WIN VERIFICATION TEST. Refer to Standard Procedure .

      No 

  4. VERIFY THE STATE OF THE WIN MODULE 
    1. Currently the secret key in the FOBIK does not match the secret key in the WIN module. Find out which component has the correct secret key for this vehicle.

      Has the WIN module just been replaced?

      Yes 

      • Go To  5.

      No 

      • Replace and program the FOBIK in accordance with the Service Information.
      • Perform the WIN VERIFICATION TEST. Refer to Standard Procedure .
  5. VERIFY THE WIN MODULE HAS BEEN INITIALIZED 
    1. Using the scan tool, go to Miscellaneous Functions and run the "Reset WIN" routine.
    2. Enter the unique 4 digit PIN number assigned to this vehicle.

      Was the 4 digit PIN accepted?

      Yes 

      • Replace and program the FOBIK in accordance with the Service Information.
      • Perform the WIN VERIFICATION TEST. Refer to Standard Procedure .

      No 

        NOTE:

        If the PCM was replaced at the same time the WIN was, install the old PCM before continuing or else the correct secret key value will not get transferred and replacing all FOBIKs will be necessary.

      • Using the scan tool, go to Miscellaneous Functions and run the "WIN Replaced" routine.
      • Using the scan tool, go to Miscellaneous Functions and run the "Program Ignition Keys or Key Fobs" routine.
      • Perform the WIN VERIFICATION TEST. Refer to Standard Procedure .
