Occupant Classification Sensor: Removal

NOTE: To prevent system failure, it is necessary to carry out the Occupant Classification System (OCS) system reset when a front passenger seat cushion is disassembled, a new cover installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset.

NOTE: Do not install a new heater mat on a front passenger seat cushion. Install a new Occupant Classification System (OCS) system service kit. Failure to follow this instruction can cause incorrect OCS system operation. Refer to Occupant Classification System (OCS) Service Kit for the Occupant Classification Sensor Removal and Installation procedure.

NOTE: An Occupant Classification System (OCS) system service kit has the electrical connector glued to the Occupant Classification System Module (OCSM). It cannot and should not be disconnected or altered.

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.

Remove the front passenger seat. For additional information, refer to SEAT SYSTEM article.
Remove the seat backrest. For additional information, refer to SEAT SYSTEM article.
Remove the seat track. For additional information, refer to SEAT SYSTEM article.
