THEFT DETERRENT SYSTEM (w/o Entry and Start System) - 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 immobiliser system. The security indicator blinks continuously due to a continuous signal received from the immobiliser system while in the armed state.
The main body ECU causes the security indicator to light up or blink only during the arming preparation state and alarm sounding states.

INSPECTION PROCEDURE

1.INSPECT CLOCK ASSEMBLY


    Camry. Acv40 Gsv40.Theft Deterrent.Theft Deterrent System (W/ Entry And Start System).Theft Deterrent System (W/O Entry And Start System) Security Indicator Light Circuit

  1. Disconnect the F3 clock connector.

  1. Apply battery voltage between the terminals of the indicator, and check the lighting condition of the security indicator.

    Standard :
    Measurement Condition
    		Specified Condition
    Battery positive (+) → Terminal F3-8 (LP)
    Battery negative (-) → Terminal F3-19 (GND1)
    		Lights up
    NOTICE:
    1. If the positive (+) lead and the negative (-) lead are incorrectly connected, the security indicator will not light up.
    2. Voltage of more than 12 V will damage the security indicator.
    3. If the voltage is too low, the security indicator will not light up.
