This circuit provides power to operate the ID code box.

If an ECM that is incompatible with the engine immobiliser system is installed, the ECM outputs this DTC.

This DTC is output when the ID code box detects an internal malfunction.

If the communication line (EFIO-IMI) to the ID code box (immobiliser code ECU) is stuck on HI output, the ECM outputs this DTC.

This DTC is output when the engine switch power source supply line is open or shorted.

This DTC is output when one of the following occurs: 1) the ECM detected errors in its own communications with the ID code box (immobiliser code ECU); 2) the ECM detects errors in the communication lines; or 3) the ECU communication ID between the ID code box (immobiliser code ECU) and ECM is different and an engine start is attempted.

This DTC is output when there is an open or short malfunction in the transponder key coil (built into the engine switch).
