CHECK SEAT FUNCTIONS .
Operate each power seat switch and check that each power seat function operates normally.

Does all function fail to operate?

Yes: Go to 2 .

No: Check the motor which does not operate. Ref. to SEATS>Power Seat System>INSPECTION>SOME MOTORS DO NOT OPERATE. (DRIVER'S SEAT WITH MEMORY FUNCTION) .
CHECK FUSE .
Check the power seat fuse inside the fuse box.

Is the fuse blown out?

Yes: Replace the appropriate fuse.

No: Go to 3 .
CHECK POWER SEAT CONTROL MODULE .
1. Turn the ignition switch to ON.
2. Check the DTC relating the power seat control module using the Subaru Select Monitor.
  NOTE: For detailed operation procedures, refer to "Application help".
Is DTC detected?

Yes: Perform the diagnosis according to the "POWER SEAT MEMORY SYSTEM (DIAGNOSTICS)" service information.

No: Go to 4 .
CHECK POWER SEAT CONTROL MODULE .
1. Turn the ignition switch to ON.
2. Display «Battery Terminal Voltage» on «Data monitor» of the power seat control module using Subaru Select Monitor.
Is the voltage 10 V or more?

Yes: Go to 7 .

No: Go to 5 .
CHECK POWER SUPPLY CIRCUIT .
1. Disconnect the power seat control module connector.
2. Measure the voltage between harness connector and chassis ground.
  Connector & terminal
  
  (R155) No. 10 (+) - Chassis ground (-):
  
  (R156) No. 8 (+) - Chassis ground (-):
  
  (R156) No. 3 (+) - Chassis ground (-):
Is the voltage 10 V or more?

Yes: Go to 6 .

No: Check body harness.
CHECK POWER SUPPLY CIRCUIT .
Measure the resistance between power seat control module harness connector and chassis ground.

Connector & terminal

(R156) No. 14 - Chassis ground:

(R156) No. 12 - Chassis ground:

Is the resistance less than 10 Ω?

Yes: Go to 7 .

No: Check body harness.
CHECK HARNESS .
1. Disconnect the power seat control module connector.
2. Measure the resistance of the following harnesses.
  Connector & terminal
  
  Slide:
