IMMOBILIZER CONTROL SYSTEM (Z13DT ENGINE MODEL) 8G3-3
ON-Board Diagnostic System
ECM and Immobilizer Control Module diagnose troubles which
may occur in the area including the following parts when the igni-
tion switch is turned to ON position.
Immobilizer Control Module
• W-line (communication line between ECM and Immobilizer
Control Module)
• Password (PWD)
• SVS lamp circuit
• Transponder (ignition key)
• FIX CODE (FC)
ECM
• SECRET KEY CODE (SKC)
• PWD
When a trouble exists in the immobilizer control system (when
Immobilizer Control Module or ECM detects a diagnostic trouble
code (DTC)), ECM stops operation of the injector and igniter.
With the ignition switch at ON (but the engine at stop) regardless
of the condition of the engine and emission control system, ECM
indicates whether some trouble has occurred in the immobilizer
control system or not by turning ON or flashing ON and OFF the
SVS lamp (1).
SVS lamp is ON, and then OFF after 3 seconds:
No trouble exists in the immobilizer control system.
SVS lamp flashes ON and OFF at 0.25-sec. intervals:
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 3 seconds at maximum.
While the diagnosis is being made, the SVS lamp stays
on and diagnosis result is abnormal, it immediately starts
flashing but if the result is normal, it remains on.
