2. While driving the vehicle, compare the "Speed" indicator to the reading on the speedometer. Check that these readings are almost equal.

   HINT: 

   The combination meter assembly receives the vehicle speed signal from the skid control ECU via CAN communication. Therefore, perform the inspection while referring to values in the Data List of the skid control ECU because it is the source of the vehicle speed signal.

   OK

   Vehicle speed displayed on the "Vehicle Sensors" screen is almost the same as the actual vehicle speed measured using the Techstream, refer to DATA LIST / ACTIVE TEST .
