1992 Volvo 240
A self-diagnostic system incorporated in the sensor monitors the SRS. If a fault is detected, the "SRS"
warning light will illuminate. The light is included in the warning indicator light cluster in the
instrument panel. Normally, the SRS warning lamp should light up when the ignition is switched on and
should go out after 10 seconds or when the engine is started. Check that this light is functioning properly
every time the car is started.
The following items are monitored by the diagnostic system:
● Sensor unit electronics integrity.
● Reserve energy supply.
● Diagnostic output circuit.
● System voltage
● Integrity of system connectors.
● Gas generator ignitor.
WARNING! If the SRS warning light stays on after the engine has started or if it comes on while you
are driving, drive the car to the nearest authorized Volvo Dealer for inspection as soon as possible.
ATTENTION! SRS VEHICLE!
THIS CAR IS EQUIPPED WITH A SUPPLEMENTAL RESTRAINT SYSTEM. TO PROVIDE
CONTINUED RELIABILITY, CERTAIN ELEMENTS OF THE SUPPLEMENTAL RESTRAINT
SYSTEM SHALL BE SERVICED OR REPLACED BY JAN. XXXX. SEE OWNERS MANUAL
FOR FURTHER INFORMATION.

The above is a sample of the decal which can be found on the left-hand door pillar.
There is no maintenance to perform on the SRS yourself. The only periodic maintenance recommended
on the SRS is that the air bag module should be replaced approximately every ten years and that the
other components in the system (wiring, connector, etc.) should also be inspected at this time. The SRS
decal on you car shows the month and year servicing is due. This service must performed by an
authorized Volvo dealer.
