TROUBLE DIAGNOSIS
Diagnosis results previously stored in the memory are displayed on the CONSULT-III screen. The stored
results are not erased until memory erasing is executed.
 “TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previ ously erased by a reset operation can be displayed
on the CONSULT-III screen.
 “ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification number.
This number will be displayed on the CONSULT-III scr een, as shown. When replacing the diagnosis sensor
unit, refer to the part number for the compatibility. Af ter installation, replacement with a correct unit can be
checked by confirming this classification number on the CONSULT-III screen.
After repair, make sure the discriminated number of diagnosis sensor unit installed to vehicle are same.
Refer to SRS-44, "
Removal and Installation".
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-III
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-III until “SELECT SYSTEM”
appears, then diagnosis mode automat ically changes to User mode.
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
 “SELF-DIAG [CURRENT]”
A current self-diagnostic result is displayed on the CONSULT-III screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.
 “SELF-DIAG [PAST]” Return to the “SELF-DIAG [CURRENT]” CONSULT-III screen by touching “BACK” key of CONSULT-III and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [P AST]” is not erased, the User mode shows the system
malfunction by the operation of the warning lamp even if the malfunction is repaired completely.
 “TROUBLE DIAG RECORD”
The memory of “TROUBLE DI AG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-III)INFOID:0000000001524166
 The reading of these results is accomplished “User mode” and “Diagnosis mode”.
 After a malfunction is repaired, turn ignition switch ON. Diagnosis mode returns to the User mode. At that
time, the self-diagnostic result is cleared.

System ComponentINFOID:0000000001327576
System DescriptionINFOID:0000000001327577
TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel,
and transmits a detected air pressure signal in the form of a radio
wave.
REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver receives the air pressure signal
transmitted by the transmitter in each wheel.

The BCM reads the air pressure signal received by the remote key-
less entry receiver, and controls the low tire pressure warning lamp
and the buzzer operations. It also has a judgment function to detect
a system malfunction.
LOW TIRE PRESSURE WARNING LAMP
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp is activated.
Low Tire pressure Warning Lamp Indication
Note 1: Standard air pressure is for 220 kpa (2.2 kg/cm2, 32 psi) vehicles.
RUN-FLAT TIRE WARNING LAMP
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter run-frat tire warning
lamp and buzzer are activated.
