REPAIR INSTRUCTION INSPECTION MODE PROCEDURE


  1. INSPECTION MODE

    Note

    When the vehicle is run in inspection mode for an operation such as a speedometer test, a DTC may be set. Therefore, if the warning light comes on, after canceling inspection mode, check for DTCs using the GTS and clear the DTCs.

    Tech Tips

    If the engine is warmed up and the HV battery is charged, the engine of the vehicle will stop after the vehicle stops. For example, if the engine is required to run continuously even after the vehicle stops, such as for an ignition timing check, switch to maintenance mode.


    1. The following table shows the types of inspection modes that are available, their purpose and the control that occurs in each mode.

      Mode

      (Display)

      Purpose Control

      MAINTENANCE MODE

      (2WD for measuring Exhaust Gas)


      • Inspection of ignition timing etc. when performing engine maintenance, idle speed exhaust emissions testing (CO, HC), etc.

      • Tests using a speedometer tester, two-wheel chassis dynamometer, etc.


      • Keeps the engine idling when park (P) is selected

      • Cancels traction control

      CERTIFICATION MODE

      (2WD for cutting TRC)

      Tests using a speedometer tester, two-wheel chassis dynamometer, etc. Cancels traction control
    2. Vehicle conditions


      1. Before activating inspection mode, turn the air conditioning off, start the hybrid system with park (P) selected, and check that the engine stops within several seconds after starting (engine warm up check).

      2. Activate the appropriate inspection mode and inspect the vehicle. The shift state for each test is as follows:

        Test Item Mode Shift State
        1. Vehicle straight travelling test (side slip inspection) Maintenance mode or normal mode D
        2. Braking force test Normal mode N
        3. Speedometer test Maintenance mode D
        4. Exhaust gas test (idling) Maintenance mode P
        5. Headlight test Maintenance mode or normal mode P
      3. Cancel inspection mode immediately after completion of inspection.

        Note

        Driving the vehicle without canceling inspection mode may damage the transaxle.

    3. Special notes for speedometer test

      CAUTION:

      Be sure to perform the test in maintenance mode.

      Note

      Do not perform rapid starting or quick acceleration on a speedometer tester. If rapid starting or quick acceleration is performed on a speedometer tester, damage may occur to the transaxle.


      1. Depress the accelerator pedal slowly and gradually accelerate the vehicle. Make a measurement.

      2. After the measurement, use the brakes to gradually decelerate the vehicle.

    4. Special notes for using a chassis dynamometer


      1. Always set an appropriate load before starting the test.

        Note

        Sudden acceleration or deceleration of the vehicle on a chassis dynamometer under minimal load may damage the transaxle.

    5. Activating maintenance mode (Not using the GTS)

      Perform the following steps from (A) through (D) in 60 seconds.


      1. Turn the power switch on (IG). (Step A)

      2. Fully depress the accelerator pedal twice with park (P) selected. (Step B)

      3. Fully depress the accelerator pedal twice with neutral (N) selected. (Step C)

      4. Fully depress the accelerator pedal twice with park (P) selected. (Step D)

        *1 HV System Warning Light (Blinking)

        Check that the HV system warning light in the combination meter blinks at 1 second intervals.

      6. Start the engine by turning the power switch on (READY) while depressing the brake pedal.

        Tech Tips

        The idle speed in maintenance mode is approximately 1000 rpm with park (P) selected. The engine speed increases to 1500 rpm when the accelerator pedal is depressed midway with park (P) selected. When the accelerator pedal is depressed more than midway, or when the accelerator pedal is fully depressed, the engine speed increases to approximately 2500 rpm.

    6. Activating maintenance mode (Using the GTS)


      1. Connect the GTS to the DLC3.

      2. Turn the power switch on (IG).

      3. Turn the GTS on.

      4. Enter following menus: Powertrain / Hybrid Control / Utility / Inspection Mode - 2WD for measuring Exhaust Gas.

        *1 HV System Warning Light (Blinking)

        Check that the HV system warning light in the combination meter blinks at 1 second intervals.

      6. Start the engine by turning the power switch on (READY) while depressing the brake pedal.

        Tech Tips

        The idle speed in maintenance mode is approximately 1000 rpm with park (P) selected. The engine speed increases to 1500 rpm when the accelerator pedal is depressed midway with park (P) selected. When the accelerator pedal is depressed more than midway, or when the accelerator pedal is fully depressed, the engine speed increases to approximately 2500 rpm.

    7. Activating certification mode (Not using the GTS)

      Perform the following steps from (A) through (D) in 60 seconds.


      1. Turn the power switch on (IG). (Step A)

      2. Fully depress the accelerator pedal three times with park (P) selected. (Step B)

      3. Fully depress the accelerator pedal three times with neutral (N) selected. (Step C)

      4. Fully depress the accelerator pedal three times with park (P) selected. (Step D)

    9. Deactivating inspection mode


      1. Turn the power switch off. The HV system turns off simultaneously.

        Note


        • If a DTC is set during inspection mode, the HV system warning light will illuminate.

        • When the HV system warning light illuminate during inspection mode, cancel inspection mode, and check for DTC(s).

        • Driving the vehicle without canceling inspection mode may damage the transaxle.
