Interesting problem...
From the FSM under P0500:
The vehicle speed signal is sent to the combination meter from the “ABS actuator and electric unit (control unit)” via the CAN communication line.
The combination meter then sends a signal to the ECM via the CAN communication line.
Soooo... the ABS module sends the wheel speed to the gauge cluster (via CAN bus) and it converts it to vehicle speed. The vehicle speed is then sent to the ECU.
It is possible the US cluster sends the vehicle speed in MPH to the ECU. Since the ECU is expecting KPH, it throws off the calculations and s-mode doesn't work.
^^^ just my 2¢
