Code B1A24 Chrysler Description

Whenever a Fob-Integrated-Key (FOBIK) is inserted in the Ignition Node Module (IGNM), the Radio Frequency Hub (RF-Hub) performs a self test and resynchronization routine. During the routine, the RF-Hub interrogates the FOBIK, performing various validity and performance tests. The repair of this fault condition relies on the programmed status of the FOBIK. During interrogation, the FOBIK sends a low frequency (LF) signal to the RF-Hub that includes the FOBIK identification information. This Diagnostic Trouble Code (DTC) sets if the RF-Hub receives the default, secret key status from a FOBIK. Once set, this DTC will remain active until a valid, programmed FOBIK is inserted in the IGNM and rotated through the ON position.
