DTC PROCEDURE

Step	Check	Yes	No
1 CHECK LAN SYSTEM. Inspect LAN system. < Ref. to PROCEDURE , Basic Diagnostic Procedure. >	Is LAN system normal?	Go to step 2 .	Perform the inspection according to the diagnosis for LAN system.
2 CHECK COMBINATION METER. Check that the speedometer is displayed normally. Vehicle speed signal	Is the meter display normal?	Go to step 3 .	Check the VDC. < Ref. to PROCEDURE , Basic Diagnostic Procedure. >
3 CHECK CURRENT DATA. Confirm the current data display of keyless access system using Subaru Select Monitor. Vehicle speed signal	Is the parked state or driving state displayed normally?	Go to step 4 .	Check the VDC. < Ref. to PROCEDURE , Basic Diagnostic Procedure. >
4 CHECK FUSE. Check the fuse.	Is the fuse OK?	Go to step 5 .	Replace the fuse. When the replaced fuse is blown immediately, check the power supply circuit for short-circuited.
5 CHECK HARNESS. Disconnect the keyless access CM connector. Using a tester, measure the voltage between keyless access CM connectors. Connector & terminal (B572) No. 2 (+) - Chassis ground (-):	Is the voltage 9.5 - 16 V?	Go to step 6 .	Check the power supply circuit.
6 CHECK HARNESS. Using a tester, measure the resistance between the keyless access CM connector and chassis ground. Connector & terminal (B572) No. 11 - Chassis ground:	Is the resistance less than 1 Ω?	Go to step 7 .	Repair or replace the open circuit of harness.
7 CHECK HARNESS. Disconnect the keyless access CM connector. Disconnect the combination meter connector. Using a tester, measure the resistance between the keyless access CM connector and VDC CM connector. Connector & terminal (B572) No. 27 - (B310) No. 27:	Is the resistance less than 1 Ω?	Go to step 8 .	Repair or replace the open circuit of harness.
8 CHECK HARNESS. Using a tester, measure the resistance between the keyless access CM connector and chassis ground. Connector & terminal (B572) No. 27 - Chassis ground:	Is the resistance 10 kΩ or more?	Go to step 9 .	Repair or replace the short circuit of the harness.
9 CHECK KEYLESS ACCESS CM. Connect each connector. Using the Subaru Select Monitor, measure the waveform between the terminals of keyless access CM. Connector & terminal (B572) No. 27 - Chassis ground:	Is 3.54 Hz displayed when the vehicle is driven approx. at 5 km/h?	Replace the keyless access CM. < Ref. to REMOVAL , Keyless Access CM. >	Check the VDC. < Ref. to PROCEDURE , Basic Diagnostic Procedure. >
