Step	Check	Yes	No
1 CHECK LAN SYSTEM. Inspect LAN system. <Ref. to PROCEDURE , Basic Diagnostic Procedure.>	Is the check result OK?	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.	Is the check result OK?	Go to step 3 .	Check the VDC. <Ref. to PROCEDURE , Basic Diagnostic Procedure.>
3 CHECK CURRENT DATA. Check the current data display of «Keyless Access with Push Button Start» using Subaru Select Monitor. <Ref. to READ CURRENT DATA .> «Vehicle speed signal»	Is the display normal according to the parked state or driving state?	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.	Go to step 4 .
4 CHECK HARNESS (OPEN CIRCUIT). 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 CM connector. Connector & terminal Engine type FA with EyeSight (B574) No. 27 - (B310) No. 26: Engine type FA without EyeSight (B574) No. 27 - (B310) No. 30:	Is the resistance less than 1 Ω?	Go to step 5 .	Repair or replace the open circuit of harness.
5 CHECK HARNESS (OPEN CIRCUIT). 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 30 kΩ or more?	Go to step 6 .	Repair or replace the short circuit of the harness.
6 CHECK Keyless Access Control Module. Connect each connector. Using the Subaru Select Monitor, measure the waveform between the Keyless Access Control Module connector and chassis ground. Connector & terminal (B574) No. 27 - Chassis ground:	Is 3.54 Hz displayed when the vehicle is driven approx. at 5 km/h (3 MPH)?	Replace the Keyless Access Control Module. <Ref. to Keyless Access Control Module .>	Check the VDC. <Ref. to PROCEDURE , Basic Diagnostic Procedure.>
