DIAGNOSTIC 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 . Remove 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 control module connector. Using a tester, measure the voltage between keyless access control module 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 control module 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 control module connector. Disconnect the combination meter connector. Using a tester, measure the resistance between the keyless access control module connector and VDC control module connector. Connector & terminal (B574) No. 27 - (B310) No. 30:	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 control module connector and chassis ground. Connector & terminal (B574) 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 CONTROL MODULE . Connect each connector. Using the Subaru Select Monitor, measure the waveform between the terminals of keyless access control module. Connector & terminal (B574) No. 27 - Chassis ground:	Is 3.54 Hz displayed when the vehicle is driven approx. at 5 km/h?	Replace the keyless access control module. <Ref. to KEYLESS ACCESS CONTROL MODULE .>	Check the VDC. <Ref. to PROCEDURE , Basic Diagnostic Procedure.>
