Occupant Detection System
- When any of the following operation has been done, be sure to perform [Rezeroing] of occupant detection system. Ref. to OCCUPANT DETECTION (DIAGNOSTICS)>REZERO .
- Replacing occupant detection system
- Removing and disassembling passenger's seat
- Loosening passenger's seat bolt
- The load sensor of the occupant detection system (passenger seat only) is fixed to the cushion frame assembly. Never remove the load sensor from the cushion frame assembly.
- The cushion pad, cushion cover, occupant detection control module and seat harness can be replaced as a single unit. When the cushion frame assembly is replaced, the occupant detection control module, seat harness and load sensor are assembled. When replacing the cushion frame assembly, do not touch the load sensor to avoid electrical damage.
- If the seat cushion cover is removed, make sure to replace the hang wire on the seat cushion side with a new wire.
- Never connect the battery in reverse polarity. Occupant detection system may be destroyed instantly.
- Do not disconnect the battery cables while the engine is running. A large counter electromotive force will be generated in the generator, and this voltage may damage electronic parts such as occupant detection control module.
- Before disconnecting the connectors of each sensor and control module, be sure to turn the ignition switch to OFF and wait for 60 seconds or more. Occupant detection control module may be damaged.
- Every occupant detection system-related part is a precision part. Do not drop them.
- Do not use electrical test equipment on wiring harness and connector circuits of the airbag system.
- Be careful not to damage the airbag system wiring harness when servicing the occupant detection system.
- Refer to CAUTION in Airbag System when repairing the occupant detection system. Ref. to AIRBAG SYSTEM>General Description>CAUTION .
