SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEACTIVATION AND REACTIVATIONDeactivation
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: 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: Never probe the connectors on the safety canopy module. Doing so can result in safety canopy deployment, which can result in personal injury.
WARNING: The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.
WARNING: To reduce the risk of personal injury, do not use any memory saver devices.
NOTE: If a seat equipped with a seat-mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the air bag system must be depowered.
NOTE: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be removed before operating the vehicle over the road.
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: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
All vehicles
1. Turn all vehicle accessories OFF.
2. Turn the ignition switch to OFF.
3. At the smart junction box (SJB), located below the center of the instrument panel, remove the cover and the restraints control module (RCM) fuse 33 (15 A) from the SJB. See Tribute Wiring Diagram for schematic information.
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 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, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
The front impact severity sensor is located on the radiator support bracket.
The first row side impact sensors (if equipped) are located at or near the base of the B-pillars.
The second row side impact sensors (if equipped) are located on the C-pillar.
To deplete the backup power supply energy, disconnect the negative battery cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped),
6. Depower the system. See SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING.

Vehicles without safety canopies
CAUTION: Do not deactivate the safety canopy module circuit by removing the safety canopy bridge resistor from the safety canopy electrical connector.
13. If the safety canopy bridge resistor is removed, an open circuit fault will be generated by the restraints control module (RCM).
If a restraint system diagnostic tool is installed at the safety canopy electrical connector, a low resistance fault will be generated by the RCM.
Vehicles with safety canopies
NOTE: If the headliner near each B-pillar has the word "AIRBAG" embossed on it, the vehicle is equipped with safety canopy modules.

WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result In injury and possible violation of vehicle safety standards.
14. Make sure all restraint system diagnostic tool(s) that may have been installed during the repair have been removed from the vehicle and all SRS components are connected.
15. Turn the ignition switch from OFF to ON.
WARNING: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the negative battery cable is connected.
16. Repower the system. See SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING.
17. Prove out the supplemental restraint system (SRS) as follows:
Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either:
- fail to light.
- remain lit continuously.
- flash.
The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the restraints control module using a scan tool.
