2. Additional resistance are located on a forward wall of a motor compartment near the amplifier of braking. If it is difficult to get the case of resistance, then previously remove a catchment basin.
3. Disconnect the case of additional resistance and replace.


Additional resistance are established as it should be, the return to removal.
