DTC CONFIRMATION PROCEDURE
1.VEHICLE DRIVING
With CONSULT-III
1. Driving at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for 10 minutes.
2. Check all tire pressure with CONSULT-III "DATA MONITOR" within 5 minutes.
Does "DATA MONITOR" displayed the standardized value without turning low tire pressure warning lamp ON?
YES >> INSPECTION END
NO >> Go to diagnosis procedure. Refer to "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK ID REGISTRATION
With CONSULT-III
1. Perform the ID registration of all transmitters. Refer to WT-5, "ID REGISTRATION PROCEDURE: Special Repair Requirement". Transmitter ID Registration Procedure
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for 10 minutes. Then check all tire pressure with CONSULT-III "DATA MONITOR" within 5 minutes.
Can ID registration of all transmitters be completed?
YES >> GO TO 6.
NO >> GO TO 2.
2.CHECK ALL TIRE PRESSURE SIGNAL
With CONSULT-III
1. Start engine.
2. Select "DATA MONITOR" mode for "AIR PRESSUR MONITOR" with CONSULT-III.
3. Readout 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 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.
Also check harness for short to ground and short to power.
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 WT-42, "Diagnosis Procedure". Tire Pressure Receiver
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 ID REGISTRATION
Perform ID registration of all transmitters. Refer to WT-5, "ID REGISTRATION PROCEDURE: Special Repair Requirement". Transmitter ID Registration Procedure
Can ID registration of all transmitters be completed?
YES >> GO TO 6.
NO >> GO TO 7 after malfunctioning transmitter replacement.
6.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 vehicle speed become 17 km/h (11 MPH).
Does "DATA MONITOR" displayed the standardized value without turning low tire pressure warning lamp ON?
YES >> INSPECTION END.
NO >> Replace BCM.
7.CHECK ID REGISTRATION
With CONSULT-III
1. Perform ID registration of all transmitters. Refer to WT-5, "ID REGISTRATION PROCEDURE: Special Repair Requirement". Transmitter ID Registration Procedure
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for 10 minutes. Then check all tire pressures with CONSULT-III "DATA MONITOR" within 5 minutes.
Does "DATA MONITOR" displayed the standardized value without turning low tire pressure warning lamp ON?
YES >> INSPECTION END.
NO >> GO TO 2.
Special Repair Requirement
1.CHECK TIRE AIR PRESSURE
Check all tire air pressures. Refer to WT-98, "Tire". [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 WT-5, "ID REGISTRATION PROCEDURE: Special Repair Requirement". Transmitter ID Registration Procedure
Can ID registration of all transmitters be completed?
YES >> END
NO >> GO TO 1.
