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.
