DESCRIPTION

While the engine is being cranked, battery voltage is applied to terminal STA of the TCM.

If the TCM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The TCM then illuminates the MIL and stores this DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) or more for more than 20 seconds.

    READ VALUE USING GTS (STARTER SIGNAL)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / ECT / Data List / Starter Signal.


      1. Powertrain > ECT > Data List
        Tester Display Measurement Item Range Normal Condition Diagnostic Note
        Starter Signal Starter signal ON or OFF

        • ON: Engine is cranking

        • OFF: Engine switch on (IG)

    5. Check the value displayed on the GTS when the vehicle is driven at 20 km/h (12.4 mph) or more.

      CAUTION:

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.
