Ronnie Posted December 2, 2023 Share Posted December 2, 2023 Not really without buying an old ODB1 scanner that can be connected to the diagnostic port under the dash. I would try disconnecting the battery cable for about 5 minutes and then reconnect. Then try checking codes again with the CRT. 1 Link to comment Share on other sites More sharing options...
