 1.CHECK TIRE PRESSURE SIGNAL
 With CONSULT-III - Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
- Within 5 minutes, select “DATA MONITOR” for the CONSULT-III “AIR PRESSURE MONITOR”.
- Read the values that are displayed for “AIR PRESS FL”, “AIR PRESS FR”, “AIR PRESS RR”, and “AIR PRESS RL”.

Is a tire pressure of 0 kPa (Psi) displayed for all wheels? YES >>GO TO 2.NO >>GO TO 4.
 2.CHECK RECEIVER CIRCUIT
- Turn the ignition switch OFF.
- Disconnect the low tire pressure warning control unit harness connector and tire pressure receiver harness connector.
- Check the continuity between the harness connector terminals of the low tire pressure warning control unit and receiver.
