Seat with weight sensor bolt Occupant Classification System (OCS) system

NOTE: The Occupant Classification System (OCS) is part of the front passenger seat track assembly and is not serviced separately.

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

NOTE: An 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.
