CONSULT-II FunctionNHS0007E
DIAGNOSIS MODE FOR CONSULT-II

“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-II screen in real time. This refers to a malfunctioning part requiring
repairs.

“SELF-DIAG [PAST]”
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.

“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II 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-II 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-II screen.
After repair, make sure the discriminated number of diagnosis
sensor unit installed to vehicle are same. Refer to SRS-49,
"ECU DISCRIMINATED NO." .
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-II
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-II 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-II 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-II screen by touching “BACK” key of CONSULT-II 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-II)NHS0007F

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

DIAGNOSTIC PROCEDURE 2
Refer to GI-38, "CONSULT-II Start Procedure" .
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Touch “SELF-DIAG [CURRENT]”.
2. Diagnostic code is displayed on “SELF-DIAG [CURRENT]”.
a. If no malfunction is detected on “SELF-DIAG [CURRENT]” even though malfunction is detected in “SRS Operation Check”,
check the battery voltage. If the battery voltage is less than 9V,
charge or replace the battery. Then go to SRS-25, "
DIAGNOS-
TIC PROCEDURE 3" . If the battery voltage is OK, go to SRS-
27, "DIAGNOSTIC PROCEDURE 4 (CONTINUED FROM
DIAGNOSTIC PROCEDURE 2)" to diagnose the following
cases:

Self-diagnostic result “SELF-DIAG [PAST]” (previously stored
in the memory) might not be erased after repair.

The SRS system malfunctions intermittently.
