  3. TEST MODE FOR VEHICLE SPEED SENSOR SIGNAL (WITH INTELLIGENT TESTER) 

    HINT:

    The manufacturer uses the test mode to check the vehicle speed sensor operation.

    1. Connect the intelligent tester to the DLC3.
    2. Allow the engine to idle.
    3. Select the tester menus: DIAGNOSTIC, OBD/ MOBD, ABSA/SC and SIGNAL CHECK. The ABS warning light will blink.

    4. Drive the vehicle straightforward at 55 km/h (34 mph) or higher for several seconds. Then, do not turn the steering wheel and do not spin the wheels. The ABS warning light will go OFF when the signal check is complete.
    5. Stop the vehicle and do not turn the ignition switch OFF.
    6. Check the DTCs.

      If DTCs are set, perform the inspection procedure depends on DTCs.
