Multiplex Control Inspection Connector Circuit
- Turn ignition off. Check continuity of solid state circuit in driver's underdash fuse/relay box between terminal A15 of driver's multiplex control unit 24-pin harness connector and multiplex control inspection connector terminal No. 3. See WIRING DIAGRAMS . If continuity exists, go to next step. If continuity does not exist, repair open in circuit or replace driver's underdash fuse/relay box as necessary.
- Check continuity of solid state circuit in driver's underdash fuse/relay box between ground and multiplex control inspection connector terminal No. 1. See WIRING DIAGRAMS . If continuity exists, circuit is okay. If continuity does not exist, repair open in ground circuit between inspection connector and ground under middle of dashboard, or replace driver's underdash fuse/relay box as necessary.
