I posted yesterday under First Gen forum and no responses. In a nutshell-2004 Mdx into Honda dealer for replacement main rear seal and canshaft thrust plate o rings. Job done-1/2 mi out of the lot and blinking D on dash. Take it back-diagnose speed sensor bad. About to let me take car, part had to be ordered, and as they pull it out of shop again, VSA comes on. Have a loaner and waiting for part. Has any body experienced anything like this and what was the resolution?
Thanks
In my experience with my 02 RSX, the blinking D was a transmission issue (had to replace a pressure sensor) and the VSA was caused by a bad wheel speed sensor.
Both were clearly identified by obd2 scan codes, did you try a scanner to get more specific on what the car computer thinks is wrong?
