DIAGNOSIS SYSTEM (BCM)

CONSULT-III Function (BCM)

INFOID:0000000004205303

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.

Data Monitor Mode

Diagnostic mode

Description

Work Support

Supports inspections and adjustments. Commands are transmitted to the BCM
for setting the status suitable for required operation, input/output signals are re-
ceived from the BCM and received data is displayed.

Data Monitor

Displays BCM input/output data in real time.

Active Test

Operation of electrical loads can be checked by sending drive signal to them.

Self-Diagnostic Result

Displays BCM self-diagnosis results.

CAN Diagnostic Support Monitor

The result of transmit/receive diagnosis of CAN communication can be read.

ECU Identification

BCM part number can be read.

Configuration

Performs BCM configuration read/write functions.

DIAGNOSIS SYSTEM (BCM)

NOTE:
Before performing the self-diagnosis, be sure to register the ID, or the actual malfunction location may be different from that displayed on
CONSULT-III.

Self-Diagnosis (Without CONSULT-III)

INFOID:0000000004471324

SELF DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-III)

1. Turn ignition switch ON.

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

3. 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

1.

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.

NO

>> Refer to

WT-14, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000004205305

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

1.

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

NO

>> GO TO 3

2.

CHECK TIRE PRESSURE RECEIVER CONNECTOR

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

YES

>> Repair or replace tire pressure receiver connector.

NO

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

BCS-96, "Removal and Installation"

.

3.

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-68, "Removal and Installation"

.

NO

>> GO TO 4

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).

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

YES

>> Inspection End.
