The Steering Lock Does Not Operate

CAUTION: When the keyless access CM (Control Module) or steering lock CM (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.

DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK DTC. Read keyless access system DTCs 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 system 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 «Code collation result between smart ECM and ID code box» of keyless access system. < Ref. to READ CURRENT DATA . >	Is the status normal?	Go to step 5.	Replace the keyless access CM (Control Module). < Ref. to REMOVAL , Keyless Access CM (Control Module). >
5 CHECK CURRENT DATA. Using the Subaru Select Monitor, display the current data «Code collation result between steering locked ECM and ID code box» of keyless access system. < Ref. to READ CURRENT DATA . >	Is the status normal?	Go to step 6.	Replace the steering lock CM (Control Module). < Ref. to REMOVAL , Steering Lock CM (Control Module). >
6 CHECK CURRENT DATA. Using Subaru Select Monitor, display the current data «Steering lock lock/unlock command reception history» of keyless access system. < 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 CM (Control Module). < Ref. to REMOVAL , Keyless Access CM (Control Module). >
7 CHECK STEERING LOCK CM (Control Module). Using a tester, measure the waveform between steering lock CM (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 (B424) No. 3 - (B424) No. 1:	Is the waveform immediately after opening the driver's side door abnormal?	Replace the steering lock CM (Control Module). < Ref. to REMOVAL , Steering Lock CM (Control Module). >	Go to step 8.
8 CHECK WIRING HARNESS. Disconnect the keyless access CM (Control Module) connector and the steering lock CM (Control Module) connector. Using a tester, check continuity between the keyless access CM (Control Module) connector and steering lock CM (Control Module) connector. Connector & terminal (B424) No. 3 - (B574) No. 29:	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 CM (Control Module) connector and chassis ground. Connector & terminal (B572) No. 11 - Chassis ground:	Is there continuity?	Replace the keyless access CM (Control Module). < Ref. to REMOVAL , Keyless Access CM (Control Module). >	Repair or replace the open circuit of harness.
