Self-diagnosis System
23-62
SRS
System Description (cont’d)
A self-diagnosis circuit is built into the SRS unit; when the ignition switch is turned ON (II), the SRS indicator comes on
and goes off after about 6 seconds if thesystem is operating normally. If the indicator does not come on, or does not
go off after 6 seconds, or if it comes on while driving, it indicates an abnormality in the system. The system must be
inspected and repaired as soon as possible. For better serviceability, the SRS unit memory stores a DTC that relates to
the cause of the malfunction, and the unit is connected to the data link connector circuit. This information can be read
with the HDS when it is connected to the DLC (16P) (see page 23-38).
