Erasing Trouble Codes

  1. Codes cannot be erased until all codes have been displayed at least once. To erase code, hold button down for more than 5 seconds, then release. LED will light 3 seconds later to confirm trouble code(s) have been erased. Hold button down for more than 5 seconds again and release. LED should go off. Trouble code should now be erased.
  2. To ensure trouble code is erased, turn ignition off, then on again. Ensure trouble code is erased by briefly pushing test button. If Code 1-1-1 (no faults found) is displayed, trouble codes have been erased. If trouble codes are still displayed, repeat step 1).
