Conditions for Setting the DTC

The ECM detects that the commanded state of the MIL driver and the actual state of the control circuit do not match for one second.

• Should a short circuit to B+ or an open circuit occur on the MIL control circuit, the MIL must be commanded ON for the DTC to set. A short circuit to ground failure on the MIL control circuit can be detected immediately by the ECM in the commanded OFF state.
