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 21
Scheme 22
- 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.

REGISTRATION CHART
REGISTRATION BODY INTEGRATED UNIT (FUNCTION 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, or User Customizing 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, or User Customizing 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". |
- Connect SDI to data link connector located in the lower portion of the instrument panel (on the driver's side). CAUTION: Do not connect the scan tools other than the Subaru Select Monitor.
- Start the PC.
- Turn the ignition switch to ON (engine OFF) and run the "PC application for Subaru Select Monitor".
- On «Main Menu» display, select {Each System Check}.
- On «System Selection Menu» display, select {Integ. unit mode}.
- Click the [OK] button after the control module name {Integrated unit} is displayed.
- On «Integ. unit mode failure diag» display, select {Unit customizing}.
- Change the setting with UP/DOWN key. List of body integrated unit registration item NOTE: Setting is different depending on the grade of vehicle.
