 Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnostic results can be read by us ing “AIR BAG” warning lamp and/or CONSULT-III.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function 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” wa rning lamp and CONSULT-III are as follows:
HOW TO PERFORM TROUBLE DIAGNOSIS FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malf unction. It is important to fully understand the symp-

With TROUBLE DIAG RECORD, diagnosis results previ ously erased by a reset operation can be displayed
on the CONSULT-III 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-III scr een, as shown. When replacing the diagnosis sensor
unit, refer to the part number for the compatibility. Af ter installation, replacement with a correct unit can be
