DTC DETECTION LOGIC






DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
With CONSULT-III
1. Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
2. Perform BCM (AIR PRESSURE MONITOR) self-diagnosis.
Is DTC "C1724", "C1725", "C1726", "C1727" detected?
YES - Perform trouble diagnosis. Refer to C1724.
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 40 km/h (25 MPH) or more, then drive normally for 10 minutes.
Can ID registration of all transmitters be completed?
YES - GO TO 2.
NO - GO TO 5.
2.CHECK TIRE PRESSURE SIGNAL
With CONSULT-III
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-III "DATA MONITOR" to display the tire pressure for all wheels.
Are all tire pressures displayed 0 kPa?
YES - GO TO 3.
NO - GO TO 6.
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 the 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 damaged parts.
4.CHECK TIRE PRESSURE RECEIVER POWER SUPPLY CIRCUIT
1. Connect the BCM harness connector.
2. Turn the ignition switch ON.

CAUTION:
Never start the engine.
3. Check the voltage between the BCM harness connector and ground.





Is the inspection result normal?
YES - GO TO 5.
NO - Repair or replace damaged parts.
5.CHECK TIRE PRESSURE RECEIVER
Check tire pressure receiver. Refer to Diagnosis Procedure.
Is the inspection result normal?
YES - Replace tire pressure receiver. Refer to Exploded View.
NO - GO TO 6.
6.CHECK ID REGISTRATION
Perform ID registration of all transmitters. Refer to Special Repair Requirement.
Can ID registration of all transmitters be completed?
YES - GO TO 7.
NO - Replace the malfunctioning transmitter. Refer to Exploded View.
7.CHECK TIRE PRESSURE MONITORING SYSTEM
With CONSULT-III
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-III "DATA MONITOR" to display the tire pressure for all wheels.
Is the inspection result normal?
YES - Replace the malfunctioning transmitter. Refer to Exploded View.
NO - Replace BCM. Refer to [1][2]Specifications.




Special Repair Requirement
1.CHECK TIRE PRESSURE
Check all tires for tire pressures. Refer to [1][2]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.
