GENERAL DESCRIPTION

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-4

ON-BOARD DIAGNOSTIC/SRS WARNING LIGHT 
FUNCTION

The diagnosis unit monitors the SRS system and stores data 
concerning any detected faults in the system. When the ignition 
switch is in "ON" or "START" position, the SRS warning light 
should illuminate for about seven 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 seven 

seconds.

3. The SRS warning light illuminates while driving.
If a vehicle's SRS warning light is in any of these three condi-
tions, the SRS system must be inspected, diagnosed and ser-
viced in accordance with this manual.
