2000 Honday Odyssey ECU not communicating with reader
 

2000 Honda Odyssey - CEL light came on recently and went to get the codes read but the reader can't communicate with the ecu. Last year the transmission was rebuilt and I'm wondering if there could be something with the repair (ie wiring not hooked up right, something loose etc) that could affect the connection with the ecu. Had the ecu read a few months before the transmission rebuild and it connected fine. Haven't checked the wiring around the transmission yet.
