STEPCHECKYESNO

1.CHECK FUSE.

1) Turn the ignition switch to OFF.

2) Check the fuse of the DCM.

Is there any fault?

Replace the fuse. If the replaced fuse blows out easily, repair the ground short circuit in harness between the fuse — DCM connector.

Subaru Select Monitor > INSPECTION">Go to Step 2.

2.CHECK HARNESS (OPEN CIRCUIT).

1) Disconnect the DCM connector.

2) Turn the ignition switch to ON.

3) Using a tester, measure the voltage between DCM connector (harness side) and the chassis ground.

Connector & terminal

(i270) No. 8 (+) — Chassis ground (−):
(i270) No. 10 (+) — Chassis ground (−):

Is the voltage 10 V or more?

Subaru Select Monitor > INSPECTION">Go to Step 3.

Repair the open circuit in the wiring harness between fuse and DCM connector.

3.CHECK HARNESS (OPEN CIRCUIT).

1) Turn the ignition switch to OFF.

2) Using a tester, measure the resistance between DCM connector (harness side) and the chassis ground.

Connector & terminal

(i270) No. 14 — Chassis ground:

Is the resistance 1 ? or less?

Subaru Select Monitor > INSPECTION">Go to Step 4.

Repair the open circuit in the wiring harness between fuse and DCM connector.

4.CHECK LAN SYSTEM.

1) Inspect LAN system.

Is there any fault?

Perform the inspection according to the diagnosis for LAN system.

Subaru Select Monitor > INSPECTION">Go to Step 5.

5.CHECK TELEMATICS.

Using the Subaru Select Monitor, communicate with the telematics system.

Is communication possible?

Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.
