Diagnostic Procedure

DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK STEERING LOCK CM. Disconnect the push button ignition switch connector. Disconnect the keyless access CM connector. Using the tester, measure the resistance between terminals. Connector & terminal (i150) No. 14 - (i242) No. 1: (i150) No. 9 - (i242) No. 9: (i150) No. 10 - (i242) No. 7: (i150) No. 8 - (i242) No. 24:	Is the resistance less than 1 Ω?	Go to step 2 .	Repair or replace the open circuit of harness.
2 CHECK HARNESS. Using the tester, measure the resistance between terminals. Connector & terminal (i150) No. 14 - Chassis ground: (i150) No. 9 - Chassis ground: (i150) No. 10 - Chassis ground:	Is the resistance 10 kΩ or more?	Go to step 3 .	Repair or replace the short circuit of the harness.
3 CHECK PUSH BUTTON IGNITION SWITCH. Replace the push button ignition switch. < Refer to PUSH BUTTON IGNITION SWITCH . > Using the Subaru Select Monitor, clear the memory. Use the Subaru Select Monitor and read DTCs.	Is B2784 displayed?	Replace the keyless access CM. < Refer to KEYLESS ACCESS CM . >	Malfunction occurred in the push button ignition switch.
