Seat Occupant Sensor: Service and Repair
Occupant Classification Sensor
This is a "Trustmark Authoring Standards (TAS) Repair Procedure"
- TAS style procedures can be identified by steps that have no accompanying step text and the magenta color of the electrical connectors and fasteners such as nuts, bolts, clamps or clips.
- TAS removal and installation procedures use a sequence of color illustrations to indicate the order to be followed when removing/disassembling or installing/assembling a component.
- Many of the TAS procedures will have the installation information within the removal steps.
- The TAS color illustrations use a variety of symbols to indicate important details of the procedures. It is important to understand these symbols in order to properly used the TAS procedures.
Refer to How to Use TAS Procedures and TAS Symbol Glossary at Vehicle | Description and Operation for additional information on these TAS procedures.
