WARNING: This page is about a different car, the 2007 Subaru Outback and 2007 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.

IGNITION SWITCH CHECKING PROCEDURE CHART

Step	Check	Yes	No
1 CHECK FUSIBLE LINK. Remove the fusible link main SBF and SBF-6 (in main fuse box), and visually check.	Is the fusible link blown out?	Replace the fusible link main SBF or SBF-6. If the replaced fusible link has blown out easily, repair the short circuit between the fusible link and the ignition switch.	Go to step 2.
2 CHECK FOR POWER SUPPLY OF IGNITION SWITCH. Disconnect the ignition switch harness connector. Measure the voltage between harness connector terminal and chassis ground. Connector & terminal (B72) No. 3 (+) - Chassis ground (-):	Is the voltage more than 10 V?	Go to step 3.	Check the harness for open circuits and shorts between the ignition switch and fusible link.
3 CHECK IGNITION SWITCH. Insert the ignition key into ignition switch, and turn the each position. Measure the resistance between ignition switch terminals. Connector & terminal No. 3 - No. 4 (ACC position): No. 3 - No. 4 - No. 6 - No. 1 (ON position): No. 3 - No. 6 - No. 1 - No. 2 (ST position):	Is the resistance less than 1 fi when turning the ignition key to each position?	Ignition switch is normal.	Replace the ignition switch with a new part. < Ref. to REPLACEMENT . >

CAUTION: When the ignition key lock is replaced, all ignition keys also must be registered. (Refer to the "vehicle's owners manual".)
