SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEACTIVATION AND REACTIVATION
Deactivation
WARNING: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag
module. This will reduce the risk of injury in the event of an accidental deployment.
WARNING: Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in
the event of an accidental deployment.
WARNING: Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an
accidental deployment.
WARNING: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of the gas generant combustion that is
irritating to the skin. Wash your hands with soap and water afterwards.
WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
WARNING: To reduce the risk of personal injury, do not use any memory saver devices.
NOTE: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not
indicate a supplemental restraint system (SRS) fault.
NOTE: No restraint system diagnostic tools are available for the safety belt buckle pretensioners. If the ignition switch is set to RUN or START with
either the driver or passenger safety belt buckle pretensioner electrical connector disconnected, the DTC(s) for an open circuit fault will be active.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
1. Turn all vehicle accessories OFF.
2. Turn the ignition switch to OFF.
3. At the smart junction box (SJB), located below the RH side of the instrument panel, remove the restraints control module (RCM) fuse 8 (10 A)
from the SJB. For additional information, see the Mazda Truck Wiring Diagrams.
4. Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no
flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continuously, remove the correct RCM fuse before
proceeding.
5. Turn the ignition switch to OFF.
WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing
or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or
striking components near the front or side air bag sensors or RCM, such as doors, instrument panel, console, door latches, strikers, seats
and hood latches.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect
auxiliary batteries and power supplies (if equipped).
6. Disconnect the negative battery cable and wait at least one minute.
7. Remove the two driver air bag module bolts (one shown).
