TROUBLE DIAGNOSIS FOR SYSTEM

PFP:00000

Transmitter no Data

NES000KA

MALFUNCTION CODE NO. 21, 22, 23, 24

1. 

CHECK CONTROL UNIT

Drive for several minutes. Check all tire pressures with CONSULT-II “DATA MONITOR”.

Are all tire pressures displayed 0 kPa?

YES

>> GO TO 2.

NO

>> GO TO 3.

2. 

CHECK TIRE PRESSURE RECEIVER CONNECTOR

1.

Disconnect tire pressure receiver harness connector E74 (FR-LH), E75 (FR-RH), B482 (RR-RH), B115
(RR-LH).

2.

Check terminals for damage or loose connection.

3.

Reconnect harness connector.

OK or NG

OK

>> Replace low tire pressure warning control unit. Refer to 

WT-40, "Low Tire Pressure Warning Con-

trol Unit"

 , then GO TO 3.

NG

>> Repair or replace tire pressure receiver harness connector.

3. 

ID REGISTRATION

Perform ID registration of all transmitters.
Are there any tires that ID can not be registered to?

YES

>> Replace transmitter of the tire, then GO TO 5.

NO

>> GO TO 4.

4. 

VEHICLE DRIVING

Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.
Check all tire pressures with CONSULT-II “DATA MONITOR” within 15 minutes after vehicle speed becomes
17 km/h (11 MPH).

Does “DATA MONITOR ” display tire pressure as normal without any warning lamp?

YES

>> INSPECTION END

NO

>> GO TO 5.

5. 

ID REGISTRATION AND VEHICLE DRIVING

1.

Perform ID registration of all transmitters.

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-II “DATA MONITOR” within 5 minutes.

Does “DATA MONITOR” display tire pressure as normal without any warning lamp?

YES

>> INSPECTION END

NO

>> GO TO the inspection applicable to DTC.

NES000KB

MALFUNCTION CODE NO. 25, 26, 27, 28

1. 

CHECK LOW TIRE PRESSURE WARNING CONTROL UNIT AND RECEIVER CONNECTOR

1.

Turn ignition switch OFF, disconnect low tire pressure warning control unit harness connector and receiver
harness connector, and check terminal for deformation, disconnection, looseness, and so on. If there is a
malfunction, repair or replace the terminal.

2.

Reconnect harness connector securely, and perform self-diagnosis.

Does “SELF-DIAG RESULTS” display as normal without any warning lamp?

YES

>> Connector terminal connection is loose, damaged, open, or shorted.

NO

>> GO TO 2.

2. 

CHECK TIRE PRESSURE RECEIVER POWER SUPPLY AND GROUND CIRCUIT

1.

Turn ignition switch OFF, and disconnect tire pressure receiver harness connector E74, E75, B115, B482.

2.

Check continuity between tire pressure receiver harness con-
nector E74, E75, B115, B482 and ground.

3.

Turn ignition switch ON, and then check voltage between tire
pressure receiver harness connector E74, E75, B115, B482 and
ground.

OK or NG

OK

>> GO TO 3.

NG

>> GO TO 4.

3. 

CHANGE THE TIRE PRESSURE RECEIVER POSITION (EXAMPLE OF FRONT LH SIDE)

1.

Replace right from left for front and rear receivers.

2.

Perform self-diagnosis.

Is the initial indication of self-diagnosis displayed?

YES

>> GO TO 4

NO

>> Replace tire pressure receiver front RH when indicating RH tire pressure receiver malfunction.

Terminal 4 – Ground

: Continuity should exist.
