IMMOBILIZER CONTROL SYSTEM (Z10XEP / Z12XEP ENGINE MODELS) 8G4-5
With the ignition switch turned ON (but the engine at stop) regard-
less of the condition of the engine and emission control system,
ECM indicates whether a trouble has occurred in the immobilizer
control system or not by flashing or turning ON the SVS lamp (1).
SVS lamp ON:
No trouble exists in the immobilizer control system.
SVS lamp flashing ON and OFF:
ECM or immobilizer control module has detected some
trouble in the immobilizer control system.
NOTE:
As soon as the ignition switch is turned to ON position,
ECM and immobilizer control module diagnose if a trou-
ble has occurred in the immobilizer control system in
about 5 seconds at maximum.
While the diagnosis is being made, the MIL (malfunction
indicator lamp) stays on and diagnosis result is abnor-
mal, it immediately changes to flashing but if the result is
normal, it remains on.
