DTC DETECTION LOGIC

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

Repair Requirement"

.

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 

WT-17, "Diagnosis Procedure"

.

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 

WT-42, "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 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

Requirement"

.

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

Repair Requirement"

.

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.

Special Repair Requirement

INFOID:0000000001686961
