Diagnostic Procedure

DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK FUSE. Remove the fuse.	Is the fuse OK?	Go to step 2 .	Replace the fuse. When the replaced fuse is blown immediately, check the power supply circuit for short-circuited.
2 CHECK CURRENT DATA. Confirm the current data display of keyless access system using Subaru Select Monitor. {IGN SW}	Is the display normal according to the ignition switch operation?	Go to step 3 .	Go to step 5 .
3 CHECK HARNESS. Disconnect the steering lock CM connector. Using a tester, measure the resistance between the steering lock CM connector and chassis ground. Connector & terminal (B424) No. 1 - Chassis ground:	Is the resistance less than 1 Ω?	Go to step 4 .	Repair or replace the open circuit of harness.
4 CHECK HARNESS. Connect the steering lock CM connector. Using the tester, measure the voltage between terminals. Connector & terminal (B424) No. 6 (+) - (B424) No. 1 (-):	Is the voltage 11 - 14 V with IG ON? Is the voltage less than 1 V with IG OFF?	Replace the steering lock CM. < Refer to REMOVAL , Steering Lock CM. >	Check the DC power supply circuit.
5 CHECK HARNESS. Using a tester, measure the voltage between the keyless access CM connector and chassis ground. Connector & terminal (i242) No. 5 (+) - Chassis ground (-):	Is the voltage 11 - 14 V with IG ON? Is the voltage less than 1 V with IG OFF?	Replace the keyless access CM. < Refer to REMOVAL , Keyless Access CM. >	Check the DC power supply circuit.
