Tire Pressure Receiver
TIRE PRESSURE RECEIVERDescription
The tire pressure receiver (1) receives the air pressure signal transmitted by the transmitter in each wheel.
Component Function Check
1. TIRE PRESSURE MONITORING SYSTEM OPERATION
With CONSULT-III
1. Drive at a speed 40 km/h (25 MPH) or more for 10 minutes.
2. Check tire pressure with CONSULT-III "DATA MONITOR" within 5 minutes.
Is the inspection result normal?
YES >> INSPECTION END
NO-1 >> Perform BCM self-diagnosis. Refer to WT-82, "DTC Index".
NO-2 >> Proceed to diagnosis procedure. 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 >> Check BCM harness and connector.
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 BCS-41, "Diagnosis Procedure". Power Supply and Ground Circuit
Is the BCM circuit normal?
YES >> Replace tire pressure receiver.
NO >> Repair or replace BCM circuit. Replace BCM.
