Basic Diagnostic Procedure: Procedure

WARNING: This page is about a different car, the 2014 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Start the diagnosis after the engine has started. (Cruise control main switch does not turn on even if it is pressed before the engine starts.)
When performing diagnosis, observe the legal speed limit on the road.
The cancel code will also appear when the cruise control is cancelled by the driver's operation. Do not confuse them.
Be sure to get an assistant to support the diagnosis while driving, and have him/her operate the select monitor.
Before clearing the memory, be sure to record the following data. (Obtain the data before inspection because the previous trouble or temporary stop history will be cleared once the memory clear is performed.)
- All Diagnostic Trouble Codes (DTCs)
- Cancel code of stereo camera
- Current data of stereo camera
  (To obtain the data concerning camera adjustment information, previous trouble or temporary stop history, all data must be measured for a few seconds after the engine has started.)
- When the temporary stop occurs, the stereo camera may be affected by the dirt that the driver cannot recognize. In this case, cleaning of the windshield glass can reduce the development of this symptom. < Ref. to WINDSHIELD GLASS AND DASHBOARD , INSPECTION, General Description. >
