Using Hand-Held Tester

  1. SPEED SENSOR SIGNAL CHECK (TEST MODE) 

    HINT:

    • If the ignition switch is turned from on (IG) to off during test mode (SIGNAL CHECK), the DTCs of the sensor check function will be erased.
    • During test mode (SIGNAL CHECK), the skid control ECU records DTCs, if the abnormal sensor signal is received.
    1. Procedures for test mode:
      1. Turn the ignition switch off.
      2. Move the shift lever to the P position.
      3. Connect the hand-held tester to the DLC3.

    2. Check the speed sensor signal.
      1. Drive the vehicle straight forward.

        Accelerate the vehicle to a speed of 34 mph (55 km/h) or more.

      2. Depress the brake pedal and check that the ABS warning light goes off.

      HINT:

      • The sensor check may not be completed if the vehicle has its wheel spun or its steering wheel turned during this check.
      • The ABS warning light goes off when the sensor signal check has been completed and the brake pedal is depressed.
      • The ABS warning light comes on immediately after a malfunction has been detected during the speed sensor signal check.
      • Stop the vehicle.
      • Read the DTCs by following the tester screen.

    HINT:

    See the list of DTCs shown in step  3.
