Removal Procedure
Warning
When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Disabling and Enabling.
Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.
Warning
Replace the passenger presence system as a complete assembly to prevent possible injury to the occupant. All the components in the service kit are
assembled and calibrated as a unit. Using only some of the components in the service kit will cause the passenger presence system to operate improperly.

Bag(s) Arming and Disarming/Service and Repair).
2. Remove the seat cushion trim cover. Refer to Front Seat Cushion Cover Replacement (See: Body and Frame/Seats/Seat Cushion/Service and
