Ford Focus Service Manual: Supplemental Restraint System (SRS) Deactivation and Reactivation

Deactivation

WARNING: Always
carry a live airbag with the deployment door, trim cover or tear seam pointed away from the body. Do not place a live airbag down with the deployment door, trim cover or tear seam facing down. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.

WARNING: Never
probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.

WARNING: Never
disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.

WARNING: If a vehicle
has been in a crash, inspect the restraints control module (RCM) and the impact sensor (if equipped) mounting areas for deformation. If damaged, restore the mounting areas to the original production configuration. A new RCM and sensors must be installed whether or not the airbags have deployed. Failure to follow these instructions may result in serious personal injury or death in a crash.

WARNING: Do not
handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.

WARNING: To reduce
the risk of accidental deployment, do not use any memory saver devices. Failure to follow this instruction may result in serious personal injury or death.

NOTE:

The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition is ON.

NOTE:

The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

1. Turn all vehicle accessories OFF.

1. Turn the ignition switch OFF.

1. At the Smart Junction Box (SJB) , located below the LH side of the instrument panel, remove the cover and RCM fuse 32 (10A) from the SJB . For additional information, refer to the Wiring Diagram Manual.

1. Turn the ignition switch ON and visually monitor the air bag warning 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.

1. Turn the ignition switch OFF.

1. WARNING: Always
   deplete the backup power supply before repairing or installing any new front or side air bag supplemental restraint system (SRS) component and before servicing, removing, installing, adjusting or striking components near the front or side impact sensors or the restraints control module (RCM). Nearby components include doors, instrument panel, console, door latches, strikers, seats and hood latches. Refer to the Description and Operation portion of Section  501-20B for location of the RCM and impact sensor(s). To deplete the backup power supply energy, disconnect the battery ground cable and wait at least 1 minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped). Failure to follow these instructions may result in serious personal injury or death in the event of an accidental deployment.

   Disconnect the battery ground cable and wait at least one minute. For additional information, refer to Section  414-01.

1. NOTE:

   Connect the passenger air bag module electrical connector.

1. Close the glove compartment door.

1. Under the front of the driver seat, connect the seat-to-floor connector.

1. Under the front of the passenger seat, connect the seat-to-floor connector.

1. NOTE:

   RH shown, LH similar.

   Connect the LH and RH side air curtain module electrical connectors.

1. NOTE:

1. Fold the rear seats up.

1. Install RCM fuse 32 (10A) to the SJB and install the cover.

1. Turn the ignition switch ON.

1. WARNING: Make
   sure no one is in the vehicle and there is nothing blocking or placed in front of any airbag when the battery is connected. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.

   Connect the battery ground cable.

1. Prove out the SRS as follows: Turn the ignition switch from ON to OFF. Wait 10 seconds, then turn the ignition switch back to ON and visually monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator will light continuously for approximately 6 seconds and then turn off. If an air bag SRS fault is present, the air bag warning indicator will: - fail to light.
   - remain lit continuously. - flash at a 5 Hz rate (RCM not configured). The air bag warning indicator may not illuminate 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 RCM to complete the testing of the SRS . If the air bag warning indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator and any SRS fault discovered must be diagnosed and repaired. Clear all continuous DTCs from the RCM and Occupant Classification System Module (OCSM) using a scan tool.
