Speed Sensor Diagnostics: Notes
NOTE:
While diagnosing speed sensors, brake system functions as a conventional system. If ignition is turned from ON to ACC or LOCK during test mode, DTCs set during sensor check function will be erased. During test mode, ECU records all DTCs of sensor check function. By performing sensor signal check, codes are erased if normal operation is confirmed. Codes left over are codes where abnormality was found.
