    INDICATOR LIGHT CIRCUIT
    CIRCUIT DESCRIPTION
    When the TVIP system is preparing to be set, this circuit lights up the indicator light. When the system has
    been set, it continually turns the indicator light on for 0.2 seconds and turns it off for 1.8 seconds, thus the
    indicator light blinks.

    STARTER CUT RELAY CIRCUIT
    CIRCUIT DESCRIPTION
    When the TVIP system operates, the TVIP ECU controls the starter cut relay so that the relay should not
    be turned on and consequently the starter can not crank the engine.

    PROBLEM SYMPTOMS TABLE
    Proceed to the reference page shown in the table below for each malfunction symptom and troubleshoot
    each circuit.
    HINT:
    Troubleshooting of the TVIP system is based on the premise that the door lock control system and wireless
    door lock control system is operating normally. Accordingly, before troubleshooting the TVIP system, first
    make certain that the door lock control system and wireless door lock control system is operating normally.
