F 550 2WD Super Duty V10-6.8L VIN S (2000)
Supplemental Restraint System ( SRS ) Deactivation and Reactivation
Deactivation Procedure
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: 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 ECS module 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.
1. Turn all vehicle accessories OFF.
2. Turn the ignition switch to OFF.
3. At the central junction box (CJB), located below the LH side of the instrument panel, remove the cover and the electronic crash sensor (ECS)
module fuses F2 (10A) and F22 (10A).
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.
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 battery ground cable (14301) and wait at least one minute.
