What OBD2 FaultFinder shows for C01xx codes
The program reads no ABS pump, valve or brake-switch circuits. What it can do is list the code with its standard name on the Trouble Codes screen (Stored, Pending or Permanent) or in Look up a code, and keep the code list with each recording so Compare shows Gone, New or Still there between two drives. The freeze frame tab, When it happened, lists the engine readings the car stored at the moment a code was set, if the car stored one.
