Set Condition

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

When a valid FOBIK is used and the RF Hub receives a mismatching cryptology code from the PCM as part of the routine, the RF Hub will send the command to flash the Security warning lamp and set this DTC as active. The engine will not start and the DTC will remain active until the RF Hub and PCM complete a successful handshake.
