Town Car V8-4.6L (2008)
Seat With A Occupant Classification Sensor (OCS) System Service Kit (Part 2)
Removal
WARNING: Make sure the front passenger seat repair is complete, the seat and all attached components (head restraint, seat side shield,
etc.) are correctly assembled, and the seat is correctly installed to the vehicle before carrying out the System Reset. Failure to follow these
instructions may result in incorrect operation of the occupant classification sensor (OCS) system and increases the risk of serious personal
injury or death in a crash.
NOTICE: It is necessary to carry out the occupant classification sensor (OCS) system reset when a front passenger seat cushion is disassembled, a
new trim cover is installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset command. Failure to follow
this instruction may result in system failure and the incorrect operation of the OCS system.
NOTE:
-
To identify between a production occupant classification sensor (OCS) system and a OCS system service kit, inspect the occupant
classification system module (OCSM) electrical connector.
A production occupant classification sensor (OCS) system allows the disconnection of the occupant classification system module (OCSM)
electrical connector.
An OCS system service kit has the electrical connector glued to the module, it cannot and should not be disconnected or altered.
-
The heated seat element on the front passenger seat cushion is not serviceable separately. If a new heated seat element is needed on the front
passenger seat cushion, a new OCS system service kit and a new heated seat element must be installed.
-
The air bag warning indicator illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is
normal operation and does not indicate a supplemental restraint system (SRS) fault.
-
The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
