PROCEDURE
| CAUTION | Subaru Select Monitor is required for reading DTC, performing diagnosis and reading current data. Remove foreign matter (dust, water, oil, etc.) from the body integrated unit connector during removal and installation. For model with immobilizer, registration of immobilizer may be needed after the replacement of controller etc. For details, refer to the "PC application help for Subaru Select Monitor". |
Note. To check harness for open or short circuits, shake the suspected trouble spot or connector. Check List for Interview CHECK LIST FOR INTERVIEW.>

SUPPLEMENTAL RESTRAINT SYSTEM "AIRBAG"
Airbag system wiring harness is routed near the body integrated unit and twisted pair line.
| CAUTION | Do not use electric test equipment on any wiring harnesses and connectors in the airbag system. Be careful not to damage the airbag system wiring harness when servicing the body integrated unit and LAN system. |
Scheme 46
- Bus line of LAN system is twisted pair line. Be careful not to by-pass or partly unbind the twisted pair line.
- Do not make clearance between bus lines (CAN High, CAN Low).
- Difference of bus line length should be within 10 cm (3.94 in).
- Fray near the connector should be within 8 cm (3.14 in).
- If the characteristics of the twisted pair line are changed, it may extremely weaken against noise.
- When repairing the harness, connect the wires using soldering and protect it with insulating tape etc.
