Security Lamp/Indicator: Testing and Inspection
Security Indicator Light Circuit
DESCRIPTION
Even when the theft deterrent system is in the disarmed state, the security indicator blinks due to a signal output from the immobilizer system. The
security indicator blinks continuously due to a continuous signal received from the immobilizer system while in the armed state.
The main body ECU RH causes the security indicator to light up or blink only during the arming preparation state and alarm sounding state.
