Diagnostic procedure

  1. Lift up the vehicle using a garage jack and place it on rigid racks, or drive the vehicle onto free rollers.
    WARNING:
    • Before lifting up the vehicle, ensure parking brake is applied.
    • Do not use a pantograph jack in place of a rigid rack.
    • Secure a rope or wire to the front or rear towing hooks to prevent the lateral runout of front wheels.
    • Before rotating the wheels, make sure that there is no one in front of the vehicle. Besides while the wheels are rotating, make sure that no one approaches the vehicle front side.
    • Make sure that there is nothing around the wheels. For AWD model, pay attention to all four wheels.
    • While servicing, do not depress or release the clutch pedal or accelerator pedal quickly regardless of the engine speed. Quick operation may cause the vehicle to drop off the free roller.
    • To prevent the vehicle from slipping due to vibration, do not place anything between rigid rack and the vehicle.
    NOTE: On vehicles equipped with EyeSight, turn the pre-collision function to OFF.

    NOTE: Ensure the selector lever is placed in the "P" range before starting.

  7. Shift the select lever in the "D" range and drive the vehicle at 5 to 10 km/h (3 to 6 MPH).
    NOTE:
    • For AWD model, release the parking brake.
    • The rotating speed difference between front and rear wheels may illuminate the ABS warning light, but this does not indicate a malfunction. When engine control system diagnosis is finished, perform the VDC memory clearance procedure of self-diagnosis function. Refer to CLEAR MEMORY MODE .
