Occupant Classification Sensor: Removal

WARNING: This page is about a different car, the 2010 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: To prevent system failure, it is necessary to carry out the Occupant Classification Sensor (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 Sensor (OCS) system service kit. Failure to follow this instruction can cause incorrect OCS system operation. Refer to Occupant Classification Sensor (OCS) Service Kit .

NOTE: An Occupant Classification Sensor (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.
