Seat Cushion Heater Mat

Seat Cushion Heater Mat

Removal

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

NOTICE: Do not reinstall any heater mat after removal. The adhesive will not adhere correctly, causing it to bunch up or shift out of place. A new heater mat and a new foam pad must be installed. If a new heater mat is needed for a passenger seat cushion, an OCS (Occupant Classification System) service kit must be installed. Failure to follow these instructions can result in heated seat component damage, system failure or incorrect OCS (Occupant Classification System) operation.

NOTE: The passenger seat is equipped with an OCS (Occupant Classification System) bladder system, a new OCS (Occupant Classification System) service kit and a new cushion heated seat mat must be installed. REFER to Occupant Classification System (OCS) Sensor .

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