Modification-Procedure for Front Passenger Seat Removal

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 side air bag sensors are located at or near the base of the B-pillar.

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 supplier (if equipped).

CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage can result.

NOTE:
- The safing sensor is internal to the air bag Electronic Crash Sensor (ECS) module and is not replaced separately.
- This procedure should be used to modify the air bag supplemental restraint system (SRS) on an Econoline van equipped without an optional passenger air bag when the front passenger seat is being removed (cutaway builds are not affected).
- The air bag Electronic Crash Sensor (ECS) module that is released for cutaway vehicles originally built without a front passenger seat and optional passenger air bag.

1. Disconnect the battery ground cable(s).
2. Disconnect the air bag electronic crash sensor (ECS) module electrical connector.
3. Disconnect the safety belt and buckle pretensioner electrical connector.
4. Remove the front passenger seat.
5. Remove the air bag electronic crash sensor (ECS) module.
6. Install a new air bag electronic crash sensor (ECS) module.
7. Connect the battery ground cable(s).
8. Prove out the system.

NOTE: If the air bag indicator flashes a lamp fault code (LFC) during prove out, refer to Diagnostic Instructions.
