Code B1A6C Dodge Description

Whenever a Fob-Integrated-Key (FOBIK) is inserted in the Wireless Ignition Node (WIN) basestation, the WIN performs a self test and resynchronization routine. During the routine, the WIN interrogates the FOBIK for the secret key information and start the vehicle. The repair of this fault condition relies on whether the current secret key in the FOBIK is recognized by the WIN. During interrogation, the FOBIK sends a low frequency (LF) signal to the WIN that includes the current secret key.
This Diagnostic Trouble Code (DTC) sets if the WIN receives a secret key ID from the FOBIK that is not the correct secret key value stored in the WIN. This DTC will remain active until a valid, programmed FOBIK, with the correct secret key is inserted in the basestation and rotated through the ON position.
