INSPECTION PROCEDURE

PERFORM ACTIVE TEST USING INTELLIGENT TESTER (SECURITY INDICATOR)

CHECK WIRE HARNESS (THEFT WARNING ECU - SECURITY INDICATOR LIGHT)

INSPECT THEFT WARNING ECU (OUTPUT)

THEFT DETERRENT SYSTEM - Security Indicator Light Circuit


DESCRIPTION

When the theft deterrent system is in the disarmed state, the security indicator light will flash continuously if the engine immobiliser system is set, or not illuminate if the engine immobiliser system is not set.
When the theft deterrent system is in the armed state, the engine immobiliser system is automatically set and the security indicator light will flash continuously.
When the theft deterrent system is in the arming preparation state and alarm sounding state, the theft warning ECU causes the security indicator light to illuminate.
