DTC B2286 Engine Speed Signal (Without Auto Start Stop): Wiring Diagram

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.

NOTE: For the coupling connector, refer to "WIRING SYSTEM".

DIAGNOSTICS PROCEDURE

Step	Check	Yes	No
1 CHECK LAN SYSTEM. Inspect LAN system. < Ref. to PROCEDURE , Basic Diagnostic Procedure. >	Is LAN system normal?	Go to step 2 .	Perform the inspection according to the diagnosis for LAN system.
2 CHECK COMBINATION METER. Confirm that the speedometer is displayed normally.	Can the data be read normally?	Go to step 3 .	Perform the diagnosis for the engine. < Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. > < Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. >
3 CHECK CURRENT DATA. Check the current data display of «Keyless access with push button start» using Subaru Select Monitor. < Ref. to READ CURRENT DATA . > «Engine speed»	Can the data be read normally?	Even if DTC is displayed, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.	Go to step 4 .
4 CHECK HARNESS (OPEN CIRCUIT). Disconnect the keyless access control module connector. Disconnect the ECM connector. Using a tester, measure the resistance between the keyless access control module connector and ECM connector. Connector & terminal (i75) No. 7 - (B134) No. 10:	Is the resistance less than 1 Ω?	Go to step 5 .	Repair or replace the open circuit of harness.
5 CHECK HARNESS (GROUND SHORT CIRCUIT). Using a tester, measure the resistance between the keyless access control module connector and chassis ground. Connector & terminal (i75) No. 7 - Chassis ground:	Is the resistance 10 kΩ or more?	Go to step 6 .	Repair or replace the short circuit of the harness.
6 CHECK HARNESS. Connect the keyless access control module connector and ECM connector. Using the Subaru Select Monitor, measure the waveform between the keyless access control module connector and chassis ground. Connector & terminal (i75) No. 7 - Chassis ground:	Does the pulse stop when the engine is stopped, and does the pulse generate when the engine is started?	Replace the keyless access control module. < Ref. to KEYLESS ACCESS CONTROL MODULE . >	Perform the diagnosis for the engine. < Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. > < Ref. to PROCEDURE , Diagnostics for Engine Starting Failure. >
