Odometers and speedometers are no longer mechanically linked like the old days. Odometer checks should be performed separately from speedometer checks.
On my Subaru, the speedo will read high, but the ECU will read correctly if you are logging. As an aside, the tachometer also gets a bit ahead of itself under acceleration. Both are most likely done to protect you. The ECU generally knows what is going on, and the odometer may interpret differently or get a different signal than the speedometer.
