Diagnostic Test

CHECK FOR AN ACTIVE DTC 

1. Verify that the vehicle's battery is fully charged with a DVOM and use the scan tool to compare the Battery Voltage listed under "Data" in the RFH View to that of the BCM. If the vehicle's battery is not fully charged, correct this condition before proceeding.
2. Verify that all Fobs for this vehicle are present and the FOB in use is causing the DTC to set.
3. With one of the owners known good Fobs in the vehicle turn the ignition on.
4. With the scan tool, read RF Hub DTCs and record on the repair order.
5. Turn the ignition off.
6. From inside the vehicle, operate the alleged inoperative Fob in all positions several times.
7. Turn the ignition on.
8. With the scan tool, read RF Hub DTCs.

   Is the DTC active?

   Yes 

   • Replace the Fob battery, erase the DTC and operate the buttons several times, If the DTC returns, replace and reprogram the Fob.

   No 

   • Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
   • The Fob may have already been re-synchronized by being in the vehicle while it was being driven. Inform the owner of the most probable cause for this code to set and therefore causing the FobK to be inoperative.
