SUPPLEMENTAL RESTRAINT
INDICATOR (SRI)
Supplemental Restraint System
The Supplemental Restraint Indicator (SRI) is located
in the instrument cluster, with B+ power from the 10A
cluster fuse and ground controlled by the SRSCM.
When the ignition key is first turned ON, the SRI
illuminates for a bulb check, flashes 6 times and goes
OFF with no faults. When commanded by the SRSCM,
the SRI illuminates to indicate:
• A fault in the system
• Loss of ignition voltage supply to the SRSCM: lamp
turns on continuously. This might be encountered
if the harness is disconnected. This is not detected
or recorded by the SRSCM, but will cause the SRI
to illuminate.
• SRSCM not connected: lamp turns on continuously
through shorting bar on the wiring harness
connector.
There are also bulb faults which keep the SRI from
illuminating, such as:
• Bulb shorted or short to battery. In this situation,
the SRSCM will retry the SRI every 15 seconds until
the fault is repaired or the ignition is turned OFF.
• Open bulb or a short to ground condition.
