DTC CONFIRMATION PROCEDURE
1.
CHECK ID REGISTRATION AND VEHICLE DRIVING
With CONSULT-III
1.
Perform ID registration of all transmitters. Refer to
WT-5, "ID REGISTRATION PROCEDURE : Special
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.
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
INFOID:0000000001686960
1.
CHECK AIR PRESSURE SIGNAL
With CONSULT-III
1.
Start 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”, “AIR PRESS RL”.
Are all tire pressures displayed 0 kPa?
YES
>> GO TO 2.
NO
>> GO TO 4.
2.
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 3.
NO
>> Repair or replace damaged parts.
3.
CHECK TIRE PRESSURE RECEIVER
Check tire pressure receiver. Refer to
.
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 damage parts.
NO
>> Replace the tire pressure receiver.
4.
CHECK ID REGISTRATION
Perform ID registration of all transmitters. Refer to
WT-5, "ID REGISTRATION PROCEDURE : Special Repair
Can ID registration of all transmitters be completed?
YES
>> GO TO 5.
NO
>> Replace malfunctioning transmitter, then GO TO 6.
5.
CHECK TIRE PRESSURE MONITORING SYSTEM
With CONSULT-III
1.
Drive at a speed 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
becomes 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. Refer to
BCS-79, "Removal and Installation"
6.
CHECK ID REGISTRATION
With CONSULT-III
1.
Perform ID registration of all transmitters. Refer to
WT-5, "ID REGISTRATION PROCEDURE : Special
2.
Drive at a speed 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
>> Perform the self-diagnosis, inspect detected malfunction.
