On-Board Diagnostic System Description (Self-diagnosis Function)

ECM diagnoses if there is any trouble with the immobilizer control system. The diagnostic information is stored as the

"Diagnostic Trouble Code (DTC) Check".
With the ignition switch turned ON (but the engine at stop) regardless of the condition of the engine and emission
control system, ECM indicates whether there is any trouble with the immobilizer control system or not by either lighting
ON or flashing ON and OFF the immobilizer indicator lamp.
Immobilizer indicator lamp lights ON:
No trouble exists in the immobilizer control system. (After starting up the engine, the light turns OFF.)
Immobilizer indicator lamp flashes ON and OFF:
There is some trouble in the immobilizer control system. Its diagnostic information is stored in ECM.
