< FUNCTION DIAGNOSIS >

DIAGNOSIS SYSTEM (BCM)

ERASE SELF-DIAGNOSIS

With CONSULT-III

1.

Perform applicable inspection of malfunctioning item and then repair or replace. 

2.

Turn ignition switch “ON” and select “SELF-DIAG RESULTS” mode for “AIR PRESSURE MONITOR” with
CONSULT-III.

3.

Touch “ERASE” on CONSULT-III screen to erase memory.

Without CONSULT-III

• In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is

stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned “ON” and“OFF”.

• However, this information is erased by turning ignition switch “OFF” after performing self-diagnostic or by

erasing the memory using the CONSULT-III.

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

1.

CHECK ID REGISTRATION AND VEHICLE DRIVING

With CONSULT-III

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. Then check all tire pressure with CONSULT-III “DATA MONITOR” within 5 minutes.

Does “DATA MONITOR” displayed the standardized value without turning tire pressure warning lamp ON?

YES

>> INSPECTION END

NO

>> Go to diagnosis procedure. Refer to 

WT-14, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000000957868

1.

ADJUST TIRE AIR PRESSURE

1.

Adjust all tire air pressures. Refer to 

WT-95, "Tire"

.

2.

Check all tire air pressures.

Does all tire pressure data meet the specification?

YES

>> GO TO 2.

NO

>> Inspect or replace the tire or wheels and adjust the tire pressure to the specification.

2.

CHECK AIR PRESSURE SIGNAL

Drive at a speed of 40 km/h (25 MPH) or more 3 minutes, and then drive the vehicle at any speed for 10 min-
utes. Then check all tire pressure with CONSULT-III “DATA MONITOR” within 5 minutes.
