Diagnostic Procedure

2014 Subaru Outback 2.5i, Standard TransSECTION Diagnostic Procedure
DIAGNOSTIC PROCEDURE

Step Check Yes No
1 CHECK LAN SYSTEM. 
Inspect LAN system.		 Is LAN system normal? Go to step 2  . Perform the inspection according to the diagnosis for LAN system.
2 CHECK CURRENT DATA. 
Confirm the current data display of keyless access system using Subaru Select Monitor.
  • {Engine Speed}
 Can the data be read normally? Perform the diagnosis for the engine. < Refer to PROCEDURE , Basic Diagnostic Procedure. > Go to step 3  .
3 CHECK FUSE. 
Remove the fuse.		 Is the fuse OK? Go to step 4  . Replace the fuse. When the replaced fuse is blown immediately, check the power supply circuit for short-circuited.
4 CHECK HARNESS. 
  1. Disconnect the keyless access CM connector.
  2. Using a tester, measure the voltage between keyless access CM connectors.

    Connector & terminal 

    (B572) No. 2 (+) - Chassis ground (-): 

 Is the voltage 9.5 - 16 V? Go to step 5  . Check the power supply circuit.
5 CHECK HARNESS. 
Using a tester, measure the resistance between the keyless access CM connector and chassis ground.
Connector & terminal 
(B572) No. 11 - Chassis ground: 		 Is the resistance less than 1 Ω? Go to step 6  . Repair or replace the open circuit of harness.
6 CHECK HARNESS. 
  1. Disconnect the keyless access CM connector.
  2. Disconnect the ECM connector.
  3. Using a tester, measure the resistance between the keyless access CM connector and ECM connector.

    Connector & terminal 

    (B572) No. 17 - (B135) No. 15: 

 Is the resistance less than 1 Ω? Go to step 7  . Repair or replace the open circuit of harness.
7 CHECK HARNESS. 
Using a tester, measure the resistance between the keyless access CM connector and chassis ground.
Connector & terminal 
(B572) No. 17 - Chassis ground: 		 Is the resistance 10 kΩ or more? Go to step 8  . Repair or replace the open circuit of harness.
8 CHECK HARNESS. 
  1. Connect the keyless access CM connector and ECM connector.
  2. Using the Subaru Select Monitor, measure the waveform between the keyless access CM connector and chassis ground.

    Connector & terminal 

    (B572) No. 17 - 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 CM. < Refer to KEYLESS ACCESS CM . > Perform the diagnosis for the engine. < Refer to PROCEDURE , Basic Diagnostic Procedure. >

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
