Displaying & Reading Trouble Codes

DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using "AIR BAG" warning lamp 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.






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 shown.

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