CONSULT-lll FunctionNHS0000M
DIAGNOSIS MODE FOR CONSULT-LLL

“SELF-DIAG [CURRENT]”
A current self-diagnostic results (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-lll screen in real time. This refers to a malfunctioning part requiring
repairs.

“SELF-DIAG [PAST]”
Self-diagnostic results previously stored in the memory are displayed on the CONSULT-lll screen. The
stored results are not erased until memory erasing is performed.

“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnostic results previously erased by a reset operation can be dis-
played on the CONSULT-lll screen.

“ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification num-
ber. This number will be displayed on the CONSULT-lll screen, as shown. When replacing the diagnosis
sensor unit, refer to the part number for the compatibility. After installation, replacement with a correct unit
can be checked by confirming this classification number on the CONSULT-lll screen.
After repair, make sure the discriminated number of diagnosis sensor unit installed to vehicle are same.
Refer to SRS-51, "
ECU DISCRIMINATED NO." .
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-LII
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-lll until “SELECT SYSTEM”
appears, then diagnosis mode automatically changes to User mode.

HOW TO ERASE SELF-DIAGNOSTIC RESULTS

“SELF-DIAG [CURRENT]”
A current self-diagnostic result is displayed on the CONSULT-lll 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-lll screen by touching “BACK” key of CONSULT-lll 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 [PAST]” 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 DIAG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-lll)NHS0000N

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.
HOW TO CHANGE SELF-DIAGNOSTIC MODE WITHOUT CONSULT-LLL
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
After a malfunction is repaired, turn the ignition switch OFF for at least one second, then back ON. Diagnosis
mode returns to the User mode. At that time, the self-diagnostic results are cleared.
