Basic Diagnostic Procedure: Procedure

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. 
  • EyeSight temporary stop code, various cancel codes and deactivate codes are not the diagnostic trouble codes (DTCs). These codes will also appear when the EyeSight function is canceled or do not operate due to the driver's operation or environmental reasons. Do not confuse them. 
  • Be sure to get an assistant to support the diagnosis while driving, and have him/her operate the Subaru Select Monitor. 
  • Be sure to record the following data before performing the Clear Memory. (Data must be obtained before inspection because the Clear Memory operation deletes previous faults and temporary stop history.) 
    • All diagnostic trouble codes (DTCs) 
    • DTC of stereo camera (current code, history code) 
    • Freeze frame data of stereo camera 
    • Various cancel codes of stereo camera 
    • Various deactivate codes of stereo camera 
    • EyeSight temporary stop code of stereo camera 
    • Data monitor of stereo camera

  • When a temporary stop occurs, stereo camera may be affected by a small amount of dirt that would not be perceived by the driver. In this case, cleaning the windshield glass is effective.
