DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION
With CONSULT-III
1. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2. Stop the vehicle.
3. Perform self-diagnosis for “AIR PRESSURE MONITOR”.
Is DTC
“C1708”, “C1709”, “C1710” or “C1711” detected?
YES >> Proceed to WT-33, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000006225511
1.CHECK TIRE PRESSURE SIGNAL
With CONSULT-III
1. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2. Stop the vehicle.
3. Select “DATA MONITOR” for “AIR PRESSURE MONITOR” with CONSULT-III.
4. Within 5 minutes after vehicle stopped, read the val ues that are displayed for “AIR PRESS FL”, “AIR
PRESS FR”, “AIR PRESS RR”, and “AIR PRESS RL”.
Are all tire pressures displayed 0 kPa (psi)?
YES >> GO TO 2.
NO >> GO TO 5.
2.CHECK RECEIVER CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect low tire pressure warning control unit harness connector and tire pressure receiver harness connector.
3. Check the continuity between low tire pressure warning control unit harness connector and tire pressure
receiver harness connector.
