Procedure

CAUTION:
WHEN YOU ARE PERFORMING SERVICE ON OR NEAR THE SIR COMPONENTS OR THE SIR WIRING, YOU MUST DISABLE THE SIR SYSTEM. USE THE FOLLOWING PROCEDURE TO TEMPORARILY DISABLE THE SIR SYSTEM. FAILURE TO FOLLOW THE CORRECT PROCEDURE COULD CAUSE AIR BAG DEPLOYMENT PERSONAL INJURY OR UNNECESSARY SIR SYSTEM REPAIRS.

CAUTION:
THE INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE MAINTAINS A RESERVE ENERGY SUPPLY. WHEN THE VEHICLE POWER IS INSUFFICIENT TO CAUSE DEPLOYMENT OF THE AIR BAGS, THE RESERVE ENERGY SUPPLY PROVIDES THE DEPLOYMENT POWER. DEPLOYMENT POWER IS AVAILABLE FOR AS MUCH AS TEN MINUTES AFTER DISCONNECTING THE VEHICLE POWER BY ANY OF THE FOLLOWING METHODS:

^ YOU TURN OFF THE IGNITION SWITCH.

^ YOU REMOVE THE FUSE THAT PROVIDES POWER TO THE INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE.

^ YOU DISCONNECT THE VEHICLE BATTERY FROM THE VEHICLE ELECTRICAL SYSTEM.
