Initial Inspection and Diagnostic Overview
CHECK MILa. The MIL comes on when the ignition switch is turned ON and the engine is not running.
HINT: If the MIL is not illuminated, troubleshoot the MIL circuit.
b. When the engine is started, the MIL should go off. If the lamp remains on, it means that the diagnosis system has detected a malfunction or abnormality in the system.
