RAM U1197: Security Seed Response Not Received From ECM/PCM
OVERVIEWWhat Does The RAM U1197 Code Mean?
Whenever the ignition is turned on or there is a remote start active, the 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 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.
What Are The Potential Causes Of The RAM U1197 Code?
- Run/start ignition feed(s) open to the PCM
- PCM programming
