1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Enter the following menus: Chassis / Brake / Data List.

   RL Wheel Speed

4. Start the engine and perform a road test.
5. Check that the value of RL Wheel Speed changes in accordance with vehicle speed when accelerating from 0 km/h to 20 km/h (0 mph to 12 mph).

   OK

   The value of RL Wheel Speed changes in accordance with vehicle speed.

   HINT: 

   If the result of the road test is within the specified range, it is possible that this DTC was stored due to a particular situation such as brake drag, wheelspin or wheel lockup.
