1. CHECK DATA MONITOR  .

   Using the Subaru Select Monitor, check the following items in the [Data Monitor] of [Engine]. Ref. to COMMON(DIAG)>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.

   Terminals 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.
