Removal
WARNING:
-
The occupant classification sensor (OCS) rails have a built-in strain gauge which may operate incorrectly if an OCS rail is dropped by
itself, dropped after it is installed to the front passenger seat or dropped after it is installed to a front passenger seat track assembly.
Use care when handling an OCS rail before or after it is installed to the front passenger seat or seat track assembly. Failure to follow
these instructions may result in incorrect operation of the OCS system and increases the risk of serious personal injury or death in a
crash.
-
Do not disassemble the occupant classification sensor (OCS) rail or tighten or loosen any of the nuts and bolts installed to the OCS rail
body. Only the 8 bolts that attach the 2 OCS rails to the seat track may be removed and installed. Failure to follow these instructions
may result in incorrect operation of the OCS system and increase the risk of serious personal injury or death in a crash.
-
Never allow oil, grease, water or foreign contaminants to get on/in the occupant classification sensor (OCS) components or electrical
connectors. Failure to follow this instruction may result in incorrect operation of the OCS system and increases the risk of serious
personal injury or death in a crash.
-
Use care when handling the front passenger seat and track assembly. Dropping the assembly, placing excessive weight on or sitting on
a front passenger seat that is not secured in the vehicle may result in damaged seat components. 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.
CAUTION: Prevent oil and/or grease from getting on the occupant classification sensor (OCS) rail bolts as this can lead to tightening
beyond the specified torque value. Failure to follow this instruction may result in damaged or broken OCS rail bolts.
NOTE:
-
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.
-
Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic
procedure again.
-
Outboard shown, inboard similar.
1. Remove the passenger seat.
2. CAUTION: Before releasing the occupant classification sensor (OCS) rail electrical connector, push only on the tip of the connector
release tab to release the electrical connector. Do not insert the tool too deep into the OCS rail electrical connector or damage to the
electrical connector may occur.
NOTE: Note the position and the routing of the OCS rail electrical wiring, connector and wiring retainers for installation.
On the affected side, detach the 2 OCS rail wiring retainers. Then, using a suitable tool, release the tab and disconnect the OCS rail electrical
connector.
