Hi Does your scanner have ability to read inputs? If yes check Vehicle Speed Sensor see if it sending MPH to VCM. VSS located on trans. Check engine never came on? Are you getting a NO COMM on reader?

The reader shows no codes stored, the check eng. Light came on, I believe because the dash some how lost power, the whole dash went off and seemed to be in the key on mode, we ordered a new vss they don't have one here on island.
Thanks
