Powertrain Control Module

The PCM reads the fuel enable circuit to determine if fuel injection should be allowed. If the fuel enable PWM signal is not present, the PCM will not allow fuel injection. If the signal is present, the PCM will allow fuel injection and normal engine operation.

The PCM has some diagnostic features associated with the PASSKey(R) fuel enable input, including trouble code E058, the "THEFT SYSTEM PROBLEM/CAR MAY NOT RESTART" message and the "STARTING DISABLED/DUE TO THEFT SYSTEM/REMOVE IGNITION KEY" message. See DRIVER INFORMATION MESSAGES  .
