U1197 RAM Meaning

Whenever the ignition is turned on or there is a remote start active, the Radio Frequency (RF) Hub performs a self-test and resynchronization routine. During the routine, the RF Hub interrogates the FOBIK for the secret key information and performs a Controller Area Network (CAN) Bus message handshake with the Powertrain Control Module (PCM) to start the vehicle. The PCM must reply to the RF Hub that the secret key information matches to initiate the start sequence or this code will set. The Diagnostic Trouble Code (DTC) sets whenever the RF Hub performs a handshake with the PCM and does not receive a security seed response from the PCM.
