PROCEDURE

 

  • Remove foreign matter (dust, water, oil, etc.) from each control module connector during removal and installation.

  • Registration of immobilizer may be needed after the replacement of control modules, etc. For detailed procedure, refer to the “REGISTRATION MANUAL FOR IMMOBILIZER” provided as a separate volume.

 

  • To check harness for open or short circuits, shake the suspected trouble spot or connector.

  • Perform the diagnosis, and when the control module is replaced as a result of judgment that malfunction is the control module, re-check that the control module was actually malfunctioning. Replace to a new control module, and confirm that the malfunction is eliminated. Then, install the previously removed control module again and check that the malfunction reproduces again.

LAN SYSTEM (DIAGNOSTICS) > CAN bus check　
OPERATION

Systems connected to vehicle CAN bus and require communicating with the Subaru Select Monitor will be displayed.

List of the systems displayed does not mean the confirmation of communication. It displays presence or absence of the systems required. And, even when a system is equipped, it may not be displayed because of a communication trouble etc.

1.

Turn the ignition switch to ON.

2.

On [Start] screen, select [Diagnosis].

3.

On [Vehicle selection] screen, input the target vehicle information and select [OK].

4.

On [Main Menu] screen, select [CAN bus check].

5.

After a while, systems connected to vehicle CAN bus will be displayed.

6.

In communication for initializing, communication is confirmed in each control module.

 

  • This function does not function normally, when the ignition switch is OFF.

  • Optional control modules and control modules that are equipped differently depending on grades may not be displayed.

  • For detailed operation procedures, refer to “Help” of application.

LAN SYSTEM (DIAGNOSTICS) > CAN Communication Circuit Check　
PROCEDURE
1. DIAG-CAN

Trouble causes:

  • DIAG-CAN communication circuit is shorted to ground.

  • DIAG-CAN communication circuit is shorted to power supply.

  • DIAG-CAN communication circuit is shorted between lines.

  • Body integrated unit malfunction

Before performing diagnosis, refer to “CAUTION” in “General Description”. LAN SYSTEM (DIAGNOSTICS)>General Description>CAUTION

 

When measuring the resistance of CAN communication circuit, measure it in sleep status.

To enter sleep status

  • With ignition switch OFF and key or switch operation stopped, keep the doors, trunk, and rear gate all closed for one minute or more.

  • On model with the keyless access with push button start, keep the access key 2 m or more away from the vehicle.

1. CHECK BASIC DIAGNOSTIC PROCEDURE.
no

Perform the instructed procedures.

yes
2. CHECK FOR SHORT TO GROUND IN HARNESS BETWEEN DATA LINK CONNECTOR AND BODY INTEGRATED UNIT.
yes

Perform the instructed procedures.

no
3. CHECK FOR SHORT TO POWER SUPPLY IN HARNESS BETWEEN DATA LINK CONNECTOR AND BODY INTEGRATED UNIT.
no

Perform the instructed procedures.

yes
4. CHECK FOR SHORT BETWEEN LINES IN HARNESS BETWEEN DATA LINK CONNECTOR AND BODY INTEGRATED UNIT.
no

Perform the instructed procedures.

yes
5. CHECK END RESISTANCE.
yes

Perform the instructed procedures.

no

Perform the instructed procedures.

1. CHECK BASIC DIAGNOSTIC PROCEDURE.

Check that the basic diagnosis has been performed up to STEP 3.

 

Possible defective parts can be narrowed easily by inspection using Subaru Select Monitor before performing “CHECK CAN COMMUNICATION CIRCUIT” using a tester.

Was the basic diagnostic procedure performed?

2

Perform the basic diagnostic procedure. LAN SYSTEM (DIAGNOSTICS)>Basic Diagnostic Procedure>PROCEDURE

2. CHECK FOR SHORT TO GROUND IN HARNESS BETWEEN DATA LINK CONNECTOR AND BODY INTEGRATED UNIT.
1.

Turn the ignition switch to OFF.

2.

Disconnect the body integrated unit connector.

3.

Using the tester, measure the resistance between data link connector and chassis ground.

Connector & terminal

(i288) No. 6 — Chassis ground:

(i288) No. 14 — Chassis ground:

Is the resistance less than 10 Ω?

Repair or replace the short circuit to ground of the harness between data link connector and body integrated unit.

3

3. CHECK FOR SHORT TO POWER SUPPLY IN HARNESS BETWEEN DATA LINK CONNECTOR AND BODY INTEGRATED UNIT.
1.

Turn the ignition switch to ON.

2.

Using the tester, measure the voltage between data link connector and chassis ground.

Connector & terminal

(i288) No. 6 (+) — Chassis ground (−):

(i288) No. 14 (+) — Chassis ground (−):

Is the voltage 5 V or less?

4

Repair or replace the short circuit to power supply of the harness between data link connector and body integrated unit.

4. CHECK FOR SHORT BETWEEN LINES IN HARNESS BETWEEN DATA LINK CONNECTOR AND BODY INTEGRATED UNIT.
1.

Turn the ignition switch to OFF.

2.

Using the tester, measure the resistance between terminals.

Connector & terminal

(i288) No. 6 — (i288) No. 14:

Is the resistance 1 MΩ or more?

5

Repair or replace the short circuit between lines of the harness between data link connector and body integrated unit.

5. CHECK END RESISTANCE.
1.

Connect the body integrated unit connector.

2.

Using a tester, measure the resistance between terminals of data link connector.

Connector & terminal

(i288) No. 6 — (i288) No. 14:

Is the resistance 114 — 126 Ω?

CAN communication circuit is normal.

Replace the body integrated unit. SECURITY AND LOCKS>Body Integrated Unit

2. MAIN-CAN

Trouble causes:

  • MAIN-CAN communication circuit is shorted to ground.

  • MAIN-CAN communication circuit is shorted to power supply.

  • MAIN-CAN communication circuit is shorted between lines.

Before performing diagnosis, refer to “CAUTION” in “General Description”. LAN SYSTEM (DIAGNOSTICS)>General Description>CAUTION

 

  • When measuring the resistance of CAN communication circuit, measure it in sleep status.

    To enter sleep status

    • With ignition switch OFF and key or switch operation stopped, keep the doors, trunk, and rear gate all closed for one minute or more.

    • On model with the keyless access with push button start, keep the access key 2 m or more away from the vehicle.

  • When the bus line is measured, combined resistance of the end resistance (120 Ω) in ECM and the end resistance (120 Ω) in body integrated unit can be measured. The combined resistance is more than 52 Ω and less than 62 Ω with the stabilizing circuit included. If the measured resistance value becomes 52 Ω or less, main wiring harness or related lines may be shorted. Or, the combined resistance may have changed because of a resistance other than the end resistance created on the circuit. If the measured value is 62 Ω or more, there may be a malfunction such as open circuit in one of the end resistances, in the stabilizing circuit, or in the main wiring harness.

    Also, even when the resistance value falls more than 52 Ω and less than 62 Ω, related lines may be open if an error of communication for initializing or a CAN system U-code has occurred. (The resistance cannot be more than 52 Ω and less than 62 Ω if the main wiring harness is open.)

    When the bus line is measured, combined resistance of the end resistance (120 Ω) in ECM and the end resistance (120 Ω) in body integrated unit can be measured. The combined resistance is more than 52 Ω and less than 62 Ω with the stabilizing circuit included. When the measured resistance value is 52 Ω or less, main wiring harness or related lines may be shorted, or combined resistance may have changed because resistance other than end resistance is created on the circuit.

    When the CAN communication circuit is measured, combined resistance of the end resistance (120 Ω) in ECM and the end resistance (120 Ω) in body integrated unit can be measured. The combined resistance is more than 52 Ω and less than 62 Ω with the stabilizing circuit included. When the measured resistance value is 62 Ω or more, either one of the end resistances, or stabilizing circuit, or main wiring harness may have malfunction such as open circuit.

1. CHECK CONTROL MODULE.
1.

Disconnect the connectors of ECM and body integrated unit.

2.

Using a tester, measure the resistance between control module terminals.

2

Replace the control module whose value is out of the specification.

2. CHECK HARNESS (MAIN-CAN).
1.

Disconnect the steering sensor connector.

2.

Using a tester, measure the resistance between steering sensor connector and ECM connector, and between steering sensor connector and body integrated unit connector.
