DIAGNOSIS FUNCTION
The SRS Self-diagnosis results can be read by using "AIR BAG" warning lamp, "SEAT BELT" warning tamp and/or CONSULT-II. The reading 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 and/or the "SEAT BELT" warning lamp. The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the "AIR BAG" warning lamp, "SEAT BELT" warning lamp and CONSULT-II are as follows:

DIAGNOSIS MODE FOR CONSULT-II

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 cleared 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 air bag 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 below. When replacing the air bag diagnosis sensor unit, refer to the part number for compatibility. After installation, replacement with a correct unit can be checked by confirming this classification number on the CONSULT-II screen.
