1. CHECK DATA MONITOR. 

   Using the Subaru Select Monitor, check the following items in the [Data Monitor] of [Engine]. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>DATA MONITOR .

   • Main Switch
   • CC Cancel SW
   • SET/COAST Switch
   • RESUME/ACCEL Switch

   Does the display change according to the cruise control command switch operation?

   Yes:  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.

   No:  Go to  2.

2. CHECK HARNESS. 
   1. Turn the ignition switch to OFF.
   2. Disconnect the ECM connector and the steering roll connector (i72).
   3. Using a tester, measure the resistance between the ECM connector and steering roll connector.

      Connector & terminal 

      (i72) No. 12 - (B134) No. 35:

      (i72) No. 11 - (B134) No. 40:

      (i72) No. 4 - (B134) No. 50:

      Is the resistance less than 1 Ω?

      Yes:  Go to  3.

      No:  Repair or replace the open circuit in harness between the ECM connector and the steering roll connector.

3. CHECK HARNESS. 

   Using a tester, measure the resistance between the steering roll connector and chassis ground.

   Connector & terminal 

   (i72) No. 12 - Chassis ground:

   (i72) No. 11 - Chassis ground:

   (i72) No. 4 - Chassis ground:

   Is the resistance 1 MΩ or more?

   Yes:  Go to  4.

   No:  Repair or replace the short circuit to ground in harness between the ECM connector and the steering roll connector.

4. CHECK STEERING ROLL CONNECTOR. 
   1. Remove the driver's airbag module. Ref. to AIRBAG SYSTEM>DRIVER'S AIRBAG MODULE>REMOVAL .
   2. Using a tester, measure the resistance between terminals of steering roll connector.

   Terminal No.	Inspection conditions	Standard
   A4 - C12	Always	Less than 1 Ω
   A3 - C11	Always	Less than 1 Ω
   A9 - C4	Always	Less than 1 Ω

   Is the check result OK?

   Yes:  Go to  5.

   No:  Replace the steering roll connector.

5. CHECK SWITCH. 

   Check the cruise control command switch. Ref. to CRUISE CONTROL SYSTEM>CRUISE CONTROL COMMAND SWITCH>INSPECTION .

   Is the inspection result of cruise control command switch OK?

   Yes:  Replace the ECM. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO)>ENGINE CONTROL MODULE (ECM) .

   No:  Replace the cruise control command switch.
