DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
With CONSULT-III
1. Driving at a speed of 40 km/h (25 MPH) or more for 10 minutes.
2. Perform BCM self-diagnosis.
Is DTC "C1720", "C1721", "C1722", "C1723" detected?
YES - Proceed to diagnosis procedure. Refer to C1720.
NO - INSPECTION END




Diagnosis Procedure
1.CHECK ID REGISTRATION
With CONSULT-III
1. Perform the ID registration of all transmitters. Refer to Special Repair Requirement.
2. Drive at a speed of 40 km/h (25 MPH) or more for 10 minutes.
3. Check all tire pressure with CONSULT-III "DATA MONITOR" within 5 minutes.





Is the inspection result normal?
YES - GO TO 6.
NO - GO TO 2.
2.CHECK ALL TIRE PRESSURE SIGNAL
With CONSULT-III
1. Start the engine.
2. Select "DATA MONITOR" mode for "AIR PRESSURE MONITOR" with CONSULT-III.
3. Read out the value of "AIR PRESS FL", "AIR PRESS FR", "AIR PRESS RR" and "AIR PRESS RL".





Are all tire pressure displayed 0 kPa?
YES - GO TO 3.
NO - GO TO 5.
3.CHECK HARNESS BETWEEN BCM AND TIRE PRESSURE RECEIVER
1. Turn the ignition switch "OFF".
2. Disconnect BCM harness connector and tire pressure receiver harness connector.
3. Check continuity between BCM harness connector and tire pressure receiver harness connector.





4. Check continuity between BCM harness connector and ground.





Is the inspection result normal?
YES - GO TO 4.
NO - Repair or replace damage parts.
4.CHECK TIRE PRESSURE RECEIVER
Check tire pressure receiver. Refer to Diagnosis Procedure.
Is the inspection result normal?
YES - Check BCM pin terminals for damage or loose connection with harness connector. If any items are damaged, repair or replace damaged parts.
NO - Replace the tire pressure receiver.
5.CHECK TIRE PRESSURE MONITORING SYSTEM
With CONSULT-III
1. Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.
2. Check all tire pressures with CONSULT-III "DATA MONITOR" within 15 minutes after stopped vehicle.





Is the inspection result normal?
YES - GO TO 6.
NO - Replace BCM. Refer to Removal and Installation.
6.CHECK TRANSMITTER
With CONSULT-III
1. Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.
2. Check all tire pressures with CONSULT-III "DATA MONITOR" within 5 minutes after stopped vehicle.





Is the inspection result normal?
YES - INSPECTION END
NO - Replace malfunction transmitter.




Special Repair Requirement
1.CHECK TIRE AIR PRESSURE
Check all tire air pressures. Refer to [1][2]Pressure, Vacuum and Temperature Specifications.
Does all tire pressure data meet the specification?
YES - GO TO 2.
NO - Inspect or repair the tires or wheels and adjust the tire pressure to the specification.
2.PERFORM ID REGISTRATION
Perform ID registration. Refer to Special Repair Requirement.
