1.CHECK AUTO OPERATION. 1) Turn the ignition switch to OFF. 2) Using operation switch, perform power rear gate auto open/close operation from full close position or full open position.	Is auto operation activated-	Even if DTC is displayed, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.	Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2519 POWER +B OPEN
2.CHECK DTC. 1) Turn the ignition switch to ON. 2) Using the Subaru Select Monitor, read DTC of PRG CM. Read Diagnostic Trouble Code (DTC)	Is DTC B2519 displayed- (Current malfunction)	Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2519 POWER +B OPEN	Even if DTC is displayed, the circuit has returned to a normal condition at this time.

4.CHECK HARNESS. 1) Disconnect the PRG CM connector (R423). 2) Using a tester, measure the voltage between the PRG CM connector and chassis ground. Connector & terminal (R423) No. 1 (+) — Chassis ground (−):	Is the voltage 9 V or more-	Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2519 POWER +B OPEN	Repair or replace the open circuit of harness.
5.CHECK HARNESS (OPEN CIRCUIT). Using a tester, measure the resistance between the PRG CM connector and chassis ground. Connector & terminal (R423) No. 4 — Chassis ground:	Is the resistance less than 10 --	Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2519 POWER +B OPEN	Repair or replace the open circuit of harness.
6.CHECK CONNECTOR. 1) Turn the ignition switch to OFF. 2) Disconnect the PRG CM connector (R423).	Is there poor contact of connector-	Repair or replace the poor contact of connector.	Replace the PRG CM. Power Rear Gate Control Module
