Subaru Crosstrek Service Manual: Basic diagnostic procedure Procedure
EyeSight (DIAGNOSTICS) > 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.
• ECM cancel code and ACC cancel code are not the diagnostic trouble code (DTC). These codes 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.
• 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 malfunction, past malfunction)
– Freeze frame data of stereo camera
– ACC cancel code of stereo camera
– EyeSight temporary stop 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 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. General Description > INSPECTION">
