2000 Honda Odyssey - CEL came on a couple of days ago and I took it to get the code read. The reader says it can’t link up with the ecu. Tried the same reader on another car and it worked fine. The transmission was rebuilt last year (about 9 mo. ago) and I’m concerned that something was not hooked up right during the rebuild. Is this a possibility for the non-linking of the reader to the ecu? Also, last year, before the tranny rebuild, I had a reader hooked up to the ecu and it worked fine.
As a side note, the TCS light comes on sometimes after starting the car and won’t turn off. If I restart the car it will turn off and work properly. I imagine this is related, but not sure since I can’t read the code for the CEL.
