CONSULT-II FunctionNHS00094
DIAGNOSIS MODE FOR CONSULT-II
“SELF-DIAG [CURRENT]”
A current self-diagnosis 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-48,
"ECU DISCRIMINATED NO." .
PASSENGER AIR BAG
The STATUS (Readiness) of the front passenger air bag module is displayed.The STATUS displayed
(ON/OFF) depends on the signals supplied to the occupant classification system control module and
air bag diagnosis sensor unit. Refer to SRS-7, "
Occupant Classification System (OCS)" for more infoma-
tion.
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.
