DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using 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
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-III are as follows.
