I have a 2018 1500 that will not crank over, the circuit from the ECU to the starter is good and will crank when jumped via a power probe, and everything appears to be communicating fine.
I have a code;
B3902:00 - Incorrect immobilizer identifier received.
The key turns the cylinder, and you can hear relays activating, and the throttle blips, I went to disable the VATS system but there's not VATS option in the systems tab.
Thanks for the Help
