Turn the ignition switch to OFF.

2.

Disconnect the Power Seat & Remote Control Mirror CM connector.

3.

Disconnect the connector of body integrated unit.

4.

Connect the disconnected connectors.

5.

Turn the ignition switch to ON.

6.

Communicate with [Power Seat Memory] using the Subaru Select Monitor.

Is communication possible?

- 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.

Using a tester, measure the voltage between Power Seat & Remote Control Mirror CM connector and chassis ground.

Connector & terminal

(R502) No. 2 (+) — Chassis ground (−):

(R502) No. 8 (+) — Chassis ground (−):

(R502) No. 9 (+) — Chassis ground (−):

Is the voltage 9 — 16 V?

5

Repair the open circuit of the harness between Power Seat & Remote Control Mirror CM connector and the fuse.

5. CHECK HARNESS (OPEN CIRCUIT).
1.

Turn the ignition switch to OFF.

2.

Using a tester, measure the resistance between Power Seat & Remote Control Mirror CM connector and chassis ground.

Connector & terminal

(R502) No. 10 — Chassis ground:

(R504) No. 2 — Chassis ground:

Is the resistance less than 1 Ω?

Replace Power Seat & Remote Control Mirror CM. SEATS>Power Seat System
