Step	Check	Yes	No
1 CHECK SUBARU SELECT MONITOR . Connect the Subaru Select Monitor to another vehicle. Check communication condition between Subaru Select Monitor and vehicle.	Is communication performed normally?	Go to step 2 .	Subaru Select Monitor unit or diagnosis cable is faulty. Or check the fuse on the vehicle side.
2 CHECK COMMUNICATION FOR INITIALIZING ERROR . Perform the communication for initializing with each module by connecting the Subaru Select Monitor. (only for installed modules)	Is the communication possible with all modules?	Go to step 3 .	Perform the inspection using the check sheet of communication for initializing. < Ref. to CHECK USING THE CHECK SHEET OF COMMUNICATION FOR INITIALIZING , COMMUNICATION FOR INITIALIZING IMPOSSIBLE, Subaru Select Monitor. >
3 CHECK DATA LINK CONNECTOR . Use a tester to check for continuity in the ground circuit. Connector & terminal (B40) No. 4 - Chassis ground: (B40) No. 5 - Chassis ground:	Is there continuity?	Go to step 4 .	Repair or replace the open circuit.
4 CHECK DATA LINK CONNECTOR . Turn the ignition switch to ON. Using a tester, check the power supply of data link connector. Connector & terminal (B40) No. 8 (+) - Chassis ground (-): (B40) No. 16 (+) - Chassis ground (-):	Is the voltage 10 V or more?	Check the power supply circuit of each module.	Check the power supply circuits to the data link connector.
