Diagnosis Procedure

INFOID:0000000003579719

1.

CHECK TIRE PRESSURE

With CONSULT-III

1.

Adjust tire pressure to specified value. Refer to 

WT-104, "Tire Air Pressure"

.

2.

Perform the ID registration of all transmitters. Refer to

Repair Requirement"

.

3.

Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.

4.

Check all tire pressure with CONSULT-III “DATA MONITOR” within 15 minutes after stopped vehicle.

Is tire pressure indicated as 438.60 kPa (4.47kg/cm

2

, 63.60 psi) on the “DATA MONITOR” screen?

YES

>> Replace malfunctioning transmitter.

NO

>> GO TO 2.
