DTC CONFIRMATION PROCEDURE

ID REGISTRATION AND VEHICLE DRIVING

1. Carry out 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.

3. Check all tire pressures with CONSULT-III within 5 minutes.
Does “DATA MONITOR ITEM” display tire pressure as normal without any warning lamp?

YES

>> Inspection End.

>> Refer to

WT-14, "Diagnosis Procedure"

Diagnosis Procedure

INFOID:0000000006179287

MALFUNCTION CODE NO. 21, 22, 23 OR 24 (DTC C1708, C1709, C1710 OR C1711)

CHECK BCM

Drive for several minutes. Check all tire pressures with CONSULT-III.
Are all tire pressures displayed as 0 kPa?

YES

>> GO TO 2

>> GO TO 3

CHECK TIRE PRESSURE RECEIVER CONNECTOR

Check tire pressure receiver connector for damage or loose connection.
Is tire pressure receiver connector damaged or loose?

YES

>> Repair or replace tire pressure receiver connector.

>> Replace BCM, then GO TO 3. Refer to

BCS-53, "Removal and Installation"

PERFORM ID REGISTRATION

Carry out ID registration of all transmitters. Refer to

WT-6, "ID Registration Procedure"

Is there a tire that cannot register ID?

YES

>> Replace malfunctioning transmitter, then GO TO 5. Refer to

WT-48, "Transmitter (Pressure Sen-

sor)"

>> GO TO 4

DRIVE VEHICLE

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

2. Check all tire pressures with CONSULT-III within 15 minutes after vehicle speed becomes 17 km/h (11

MPH).
