TIRE PRESSURE RECEIVER

Component Function Check


1. TIRE PRESSURE MONITORING SYSTEM OPERATION

With CONSULT
1.Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2.On "DATA MONITOR", select "AIR PRESS FL", "AIR PRESS FR", "AIR PRESS RR" and "AIR PRESS RL", and check that the tire pressures match the standard value.






CAUTION:
Stop the vehicle and within 5 minutes, use CONSULT "DATA MONITOR" to display the tire pressure for all wheels.
Is the inspection result normal?
YES- INSPECTION END
NO- Perform trouble diagnosis. Refer to "Diagnosis Procedure" .


Diagnosis Procedure


1. CHECK TIRE PRESSURE RECEIVER SIGNAL

1.Turn the ignition switch ON.

CAUTION:
Never start the engine.
2.Check tire pressure receiver connector and ground signal with oscilloscope.





Is the inspection result normal?
YES- INSPECTION END
NO- GO TO 2.

2. CHECK TIRE PRESSURE RECEIVER INPUT VOLTAGE

1.Disconnect tire pressure receiver connector.
2.Check voltage between tire pressure receiver connector and ground.





Is the inspection result normal?
YES- GO TO 3.
NO- Repair or replace damaged parts.

3. CHECK TIRE PRESSURE RECEIVER GROUND CIRCUIT

1.Disconnect BCM harness connector.
2.Check continuity between BCM harness connector and tire pressure receiver connector.





3.Check continuity between BCM harness connector and ground.





Is the inspection result normal?
YES- GO TO 4.
NO- Repair or replace damaged parts.

4. CHECK BCM CIRCUIT

Inspect the BCM circuit. Refer to "Diagnosis Procedure" C1734.
