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 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 low tire pressure warning lamp ON?
YES
>> INSPECTION END
NO
>> Go to diagnosis procedure. Refer to
.
Diagnosis Procedure
INFOID:0000000001686957
1.
ADJUST TIRE AIR PRESSURE
1.
Adjust all tire air pressures. Refer to
.
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.
