DIAGNOSIS SYSTEM (BCM)

CONSULT-III Function (BCM)

INFOID:0000000005275721

CONSULT-III DIAGNOSTIC MODES

CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.

DESCRIPTION

During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter
installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.
The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.

FUNCTION

When the tire pressure monitoring system detects low inflation pressure or an internal malfunction, the low tire
pressure warning lamp in the combination meter comes on. The malfunction is indicated by the low tire pres-
sure warning lamp flashing.

SELF DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-III)

Turn ignition switch ON.

Ground the tire pressure warning check connector to initiate self diagnosis.

Compare the flashing pattern with the flash code chart below.

NOTE:
The system is normal when the low tire pressure warning lamp flashes 5 times and continues repeating. Self-
diagnosis results are erased automatically by turning the ignition switch “OFF”.

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

ID REGISTRATION AND VEHICLE DRIVING

Carry out ID registration of all transmitters.

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.

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:0000000005275725

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-54, "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

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

Check all tire pressures with CONSULT-III 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?
