TROUBLE DIAGNOSIS
Revision: November 20092006 QX56
CONSULT-II Function (AIR BAG)EHS001BA
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II FunctionEHS0016Q
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, Diagnosis mode automatically changes to User mode.
AIR BAG diagnostic mode Description
SELF-DIAG [CURRENT] A current Self-diagnosis result (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 requir-
ing repairs.
SELF-DIAG [PAST] Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The
stored results will remain 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 air bag diagnosis sensor unit for each vehicle
model is assigned with its own, individual classifi-
cation number. This number will be displayed on
the CONSULT-II screen, as shown. When replac-
ing the air bag 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 CON-
SULT-II screen.
The air bag diagnosis sensor unit discrimi-
nated number assigned is F62F.
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-6,
"Occupant Classification System (OCS)" for more
information.
