DIAGNOSIS FUNCTION

NBRS0040S01

The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II. The read-
ing of these results is accomplished using one of two modes — “User mode” and “Diagnosis mode”.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:

User mode

Diagnosis mode

Display type

“AIR BAG” warning lamp

ON-OFF operation

CONSULT-II

—

Monitoring

NOTE:
Seat belt pre-tensioner malfunction is indicated by “AIR BAG” warning lamp.

DIAGNOSIS MODE FOR CONSULT-II

NBRS0040S02

“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 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 displayed
on the CONSULT-II 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-II screen, as shown below. When replacing the diag-
nosis sensor unit, refer to the part number for the compatibility. After installation, replacement with a cor-
rect unit can be checked by confirming this classification number on the CONSULT-II screen.

For INFINITI QX4, the diagnosis sensor unit classification numbers assigned is A540.
