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 < Ref. to CHECK LIST FOR INTERVIEW . >
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK PRE-INSPECTION. Ask the customer when and how the trouble occurred using the interview check list. < Ref. to CHECK LIST FOR INTERVIEW . > | Did you interview the customer? | Go to step 2. | Interview the customer. |
| 2 BASIC INSPECTION. Check components which might affect body control. < Ref. to INSPECTION , General Description. > | Is the component that might influence the body control problem normal? | Go to step 3. | Repair or replace each component. |
| 3 CHECK DTC. Read the DTC. < Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) . > NOTE: If the communication function of the Subaru Select Monitor cannot be executed properly, check the communication circuit. < Ref. to COMMUNICATION FOR INITIALIZING IMPOSSIBLE , INSPECTION, Subaru Select Monitor. > Record all DTCs and freeze frame data. | Is DTC displayed on Subaru Select Monitor? | Go to step 5. | Go to step 4 . |
| 4 PERFORM GENERAL DIAGNOSTICS. Inspect using "General Diagnostics Table". < Ref. to GENERAL DIAGNOSTIC TABLE . > | Is result of inspection OK? | LAN system is normal. | Go to step 5 . |
| 5 PERFORM DIAGNOSIS. Correct the cause of trouble. Perform the Clear Memory Mode. < Ref. to CLEAR MEMORY MODE . > Read the DTC. < Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) . > | Is DTC displayed on Subaru Select Monitor? | Repeat step 5 until DTC is not shown. | Finish the diagnosis. |
| NOTE |

| If the communication function of the Subaru Select Monitor cannot be executed properly, check the communication circuit. < Ref. to COMMUNICATION FOR INITIALIZING IMPOSSIBLE , INSPECTION, Subaru Select Monitor. > |
DIAGNOSTIC PROCEDURE CHART
CHECK
Inspect the following item about the vehicle's state.
Scheme 24
Scheme 25
Scheme 26
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 [2-9] airbag system. Be careful not to damage the airbag system wiring harness when servicing the body integrated unit and LAN system. |
Scheme 27
Scheme 28
- 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 ITEMS REFERENCE 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 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 when ignition key is turned ON, or "Factory initial setting" of body integrated unit registrations is set to "Market". If "Factory initial 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, (model 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. |

Other than 6MT Factory initial setting Factory Factory Be sure to set to "Market". After setting change, turn the ignition switch to OFF and settle the changed settings. 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 initial setting except when installing a 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 initial setting. On the << Integ. Unit customizing >> display screen of Subaru Select Monitor, select the {Factory initial setting}.
- Change the mode from Factory to Market.
- Turn the ignition switch to OFF to settle the setting.
- 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.
