Tire Pressure Receiver
TIRE PRESSURE RECEIVERDescription
The tire pressure receiver receives the air pressure signal transmitted by the transmitter in each wheel.
Diagnosis Procedure
1.CHECK TIRE PRESSURE RECEIVER
1. Turn ignition OFF.
2. Check tire pressure receiver connector M101 terminal 2 and ground signal with oscilloscope.
Is the reference signal inputted?
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 M101 terminal 4 and ground.
Is the reference voltage inputted?
YES >> GO TO 3.
NO >> Check BCM harness and connector.
3.CHECK TIRE PRESSURE RECEIVER GROUND CIRCUIT
1. Disconnect BCM harness connector and tire pressure receiver connector.
2. Check continuity between BCM harness connector M123 terminal 137 and tire pressure receiver connector M101 terminal 1.
Also check harness for short to 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-38, "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.
