Remote Keyless Entry Receiver

REMOTE KEYLESS ENTRY RECEIVER

Description

The remote keyless entry receiver (tire pressure receiver) receives the air pressure signal transmitted by the tire pressure sensor in each wheel.


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.Perform "DATA MONITOR" in "AIR PRESSURE MONITOR" of "BCM".
3.Select "BCM" in "DATA MONITOR", and check that the tire pressures match the standard value.






CAUTION:
Stop the vehicle and within 5 minutes, use "DATA MONITOR" in "AIR PRESSURE MONITOR" of "BCM"
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 REMOTE KEYLESS ENTRY RECEIVER (TIRE PRESSURE RECEIVER) SIGNAL

1.Turn the ignition switch ON.

CAUTION:
Never start the engine.
2.Check remote keyless entry receiver (tire pressure receiver) connector and ground signal with oscilloscope.





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

2. CHECK REMOTE KEYLESS ENTRY RECEIVER (TIRE PRESSURE RECEIVER) INPUT VOLTAGE

1.Disconnect remote keyless entry receiver (tire pressure receiver) connector.
2.Check voltage between remote keyless entry receiver (tire pressure receiver) connector and ground.





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

3. CHECK REMOTE KEYLESS ENTRY RECEIVER (TIRE PRESSURE RECEIVER) GROUND CIRCUIT

1.Disconnect BCM harness connector.
2.Check continuity between BCM harness connector and remote keyless entry receiver (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" Power Supply And Ground Circuit.
Is the BCM circuit normal?
YES- Replace remote keyless entry receiver (tire pressure receiver). Refer to "Removal and Installation" Service and Repair.
NO- Replace BCM. Refer to "Exploded View" Exploded View.
