HINT:

The seat belt tension reducer system is part of the large-scale multiplex communication system. This system features shared communication wiring that reduces the wiring complexity of the communication lines. The first step in any repair is to confirm the proper operation of the communication system. Proceed with troubleshooting after the communication has been verified (see the MULTIPLEX COMMUNICATION SYSTEM - DIAGNOSTICS ).
