Occupant Classification Sensor - Service Kit: Removal
NOTE:
To identify between a production OCS system and a service OCS system service kit, inspect the OCSM electrical connector
. A service OCS system (OCS service kit) has the OCSM electrical connector glued to the OCSM. It cannot and should not be disconnected or altered.
NOTE:
The seat wiring harness will be reused. The OCS service kit connector connects to the seat wiring harness OCSM connector. The pressure sensor seat wiring harness connector will be left unplugged and secured by a tie strap.
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.
