INTRODUCTION
 Before troubleshooting, verify customer complaints.
 If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
functioning. Hold and shake these parts to make sure they are securely connected.
 When using a circuit tester to measure voltage or re sistance of each circuit, be careful not to damage or
deform connector terminals.

MALFUNCTION CODE NO. 21, 22, 23 OR 24
1.CHECK CONTROL UNIT
 Drive for several minutes. Check all tire pr essures with CONSULT-III “DATA MONITOR ITEM”.
Are all tire pressures displayed 0 kPa?
YES >> GO TO 2.

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-III “DATA MONITOR ITEM” within 15 minutes after vehicle speed
becomes 17 km/h (11 MPH).
Does
“DATA MONITOR ITEM” 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 fo r 3 minutes, and then drive the vehicle at any speed for
10 minutes. Then check all tire pressures with CO NSULT-III “DATA MONITOR ITEM” within 5 minutes.
Does
“DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?
YES >> INSPECTION END
NO >> Go to the inspection applicable to DTC.
