The Steering Lock Does Not Operate

WARNING: This page is about a different car, the 2016 Subaru Outback and 2016 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: When the keyless access control module or steering lock control module is replaced, registration of the immobilizer is required. For the relevant procedures, refer to the "REGISTRATION MANUAL FOR IMMOBILIZER" provided as a separate volume.

DIAGNOSTICS PROCEDURE

Step	Check	Yes	No
1 CHECK DTC. Read DTCs of «keyless access with push button start» using the Subaru Select Monitor. < Ref. to READ DIAGNOSTIC TROUBLE CODE (DTC) . >	Is a DTC displayed?	Perform the diagnosis according to the corresponding DTC.	Go to step 2 .
2 CHECK CURRENT DATA. Display the current data «Driver's door SW input» of body integrated unit using Subaru Select Monitor. < Ref. to READ CURRENT DATA . > Read the data when opening and closing the driver's door.	Does the data change from ON to OFF according to the opening and closing?	Go to step 3 .	Inspect door switch circuit.
3 CHECK CURRENT DATA. Display the current data «Shift P Signal» of «Keyless access with push button start» using Subaru Select Monitor. < Ref. to READ CURRENT DATA . >	Is the status displayed correctly when the shift lever is shifted from P to other than P?	Go to step 4 .	Check the P range switch and harness.
4 CHECK CURRENT DATA. Using the Subaru Select Monitor, display the current data of «Keyless access with push button start»: «Code collation result between smart ECM and ID code box». < Ref. to READ CURRENT DATA . >	Is the status normal?	Go to step 5 .	Replace the keyless access control module. < Ref. to REMOVAL , Keyless Access Control Module. >
5 CHECK CURRENT DATA. Using the Subaru Select Monitor, display the current data of «Keyless access with push button start»: «Code collation result between steering locked ECM and ID code box». < Ref. to READ CURRENT DATA . >	Is the status normal?	Go to step 6 .	Replace the steering lock control module. < Ref. to REMOVAL , Steering Lock Control Module. >
6 CHECK CURRENT DATA. Display the current data «Steering lock lock/unlock command reception history» of «Keyless access with push button start» using Subaru Select Monitor. < Ref. to READ CURRENT DATA . > While in possession of the access key, perform engine start operations, and read data within 10 seconds after starting.	Is data displayed as ON?	Go to step 7 .	Replace the keyless access control module. < Ref. to REMOVAL , Keyless Access Control Module. >
7 CHECK STEERING LOCK CONTROL MODULE. Using a tester, measure the waveform between steering lock control module terminals immediately after the following operations. Perform ignition ON, driver's side door close → shift lever "P" range, ignition OFF, and close → open the driver's side door. Connector & terminal (i47) No. 3 - (i47) No. 1:	Is the waveform immediately after opening the driver's side door abnormal?	Replace the steering lock control module. < Ref. to REMOVAL , Steering Lock Control Module. >	Go to step 8 .
8 CHECK WIRING HARNESS. Disconnect the keyless access control module connector and the steering lock control module connector. Using a tester, check continuity between the keyless access control module connector and steering lock control module connector. Connector & terminal (i47) No. 3 - (i75) No. 9:	Is there continuity?	Go to step 9 .	Repair or replace the open circuit of harness.
9 CHECK WIRING HARNESS. Using a tester, check continuity between the keyless access control module connector and chassis ground. Connector & terminal (i241) No. 21 - Chassis ground: (i75) No. 1 - Chassis ground:	Is there continuity?	Replace the keyless access control module. < Ref. to REMOVAL , Keyless Access Control Module. >	Repair or replace the open circuit of harness.
