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.

CHECK FOR AN INTERMITTENT CONDITION
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. For GPEC equipped vehicles, disconnect the battery and wait a minimum of five (5) minutes, reconnect and attempt to start the vehicle. For NGC equipped vehicles, turn the ignition on a minimum for one hour, and then attempt to start the vehicle. If the vehicle does not start, continue with the diagnostic test.

NOTE:
Verify the FOBIK in use is the FOBIK causing this DTC to set.
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 crank the engine.
4. Turn the engine off, key on.
5. With the scan tool, read the active WIN DTCs.
  Does the scan tool display: B1A35-UNIDENTIFIED KEY COMMUNICATION ERROR as Active?
  
  Yes
  - Go To 2.
  No
  - Perform the WIN INTERMITTENT TEST. Refer to Standard Procedure .
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. Turn the ignition off and 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 FOBIK (Do not program) to test the WIN module's low frequency (LF) communication
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
  - Replace and program the Wireless Ignition Node (WIN) in accordance with the Service Information. Refer to RECEIVER, Wireless Ignition Node , Removal .
    NOTE:
    With the scan tool, perform the "PEM Replace" routine in the Passive Entry Module (PEM) after the FOBIKs have been programmed.
