1. Basic Diagnostic Procedure
A: PROCEDURE
NOTE:
•To check the harness for broken wires or short circuits, shake problem spot or connector.
•Refer to “Check List for Interview”.
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Ask the customer when and how the trou-
ble occurred using the interview checklist.
2) Before performing diagnostics, check the
component which might affect VDC problems.
Is the component that might
influence the VDC problem
normal?
Go to step 2.Repair or replace
each component.
2CHECK INDICATION OF DTC.
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor to data
link connector.
3) Turn the ignition switch to ON, and the Sub-
aru Select Monitor power switch to ON.
4) Read the DTC.

NOTE:If the communication function of the Subaru Se-
lect Monitor cannot be executed normally,
check the communication circuit.
