The diagnostic unit monitors the SRS system and stores data
concerning any detected faults in the system. When the igni-

light should illuminate for about 7 seconds and then turn
off. That indicates that the SRS system is in operational order.
If the SRS warning light does any of the following, immediate
inspection by an authorized dealer is needed.
(1) The SRS warning light does not illuminate as described
above.
(2) The SRS warning light stays on for more than 7 seconds.

If a vehicle's SRS warning light is in any of these three condi-
tions when brought in for inspection, the SRS system must
be inspected, diagnosed and serviced in accordance with
this manual.
