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 25
Scheme 26
- Bus line of LAN system is twisted pair line. Be careful not to bypass 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.

REGISTRATION BODY INTEGRATED UNIT (EQUIPMENT SETTING)
| CAUTION | Body integrated unit is core of LAN system, and also can select the function of all vehicle system control. It is possible to control the original functions of vehicle when registrations of body integrated unit and function setting are corresponded to vehicle equipment. If registrations and function setting are different from vehicle equipment, vehicle system does not operate normally and diagnosis cannot be performed correctly. Pay attention to following item. Be sure to correspond registrations and function settings to vehicle equipment. Do not change the settings of vehicle improperly. Confirm key illumination does not blink or "Factory or Market setting" of body integrated unit registrations is "Market". If "Factory or Market setting" is set to "Factory," key illumination blinks when ignition key is turned ON, to notify that the settings are unconfirmed. Key illumination does not blink with ignition switch turned to ON and go off with door closed. Be sure to register immobilizer if body integrated unit is replaced with a new part, (models with immobilizer) Make a registration of immobilizer when the parts related to immobilizer have been replaced. Refer to the PC application help for Subaru Select Monitor. |

Be sure to set to "Market". Market (Confirmed) CAUTION: To perform normal operation of vehicle and diagnosis, the above settings must match the actual vehicle equipment. When body integrated unit is a new part or "Factory" mode, key illumination blinks to show equipment settings have not been completed. Check the detailed procedures of function setting. Be sure not to change Factory or Market setting except installation of new body integrated unit. NOTE: "Factory" mode: Body integrated unit has not been set yet. It can be recognized by key illumination blinking with ignition switch turned to ON. All replacement body integrated units are set to Factory mode. When replacing a body integrated unit, be sure to perform the registration operation. "Market" mode: Each settings have been set. It can be recognized by key ring illumination coming on in concocting with room light and going off with ignition switch turned to ON.
- Perform the Factory or Market setting. On the «ECM customizing" display screen of Subaru Select Monitor, select the {Factory or Market setting}.
- Change the mode from Factory to Market.
- Change the Subaru Select Monitor system selection to «Immobilizer to register the immobilizer key.
- Perform the operation according to the "PC application help for Subaru Select Monitor".
- When key registration is completed, "Do you want to register remote engine start?" is displayed. Perform registration only for equipped models.
- Perform the function setting (ECM customizing). Refer to «OPERATION»(ref-325333-S36822760772009071800000) , Function Setting (Customize) . NOTE: For details concerning the operation procedure, refer to the PC application help for Subaru Select Monitor.
