Operation is relatively simple, even without a manual you can quickly get to grips with it. Fortunately, my October 1999 Astra was recognized and it turned out to be possible to read out an error. That did not work in one go; only when the MIL light came on, an error was registered on the scanner. The car itself does not seem to have a memory for the errors because the MIL light had come on a few times but the scanner could not report an error at first, without a MIL light coming on during the measurement.
