Purpose, Function

Kickdown switch (ATX) (Applied VIN (assumed): JM3 KE2*E*D# 148107?)

• If the accelerator pedal is depressed carelessly, kickdown control will be implemented based on the accelerator pedal being determined as fully open, and vehicle shock will occur. A kickdown switch has been adopted so that it can be determined that the accelerator pedal is fully open based on the driver’s intention of depressing the accelerator pedal for kickdown.

Construction

• The accelerator pedal has a built-in APP sensor and kickdown switch (ATX).

  

  
  

• For the APP sensor, refer to CONTROL SYSTEM..

• The driver can control the kickdown by knowing the amount of accelerator depression.

• The kickdown switch is only a measure of the kickdown. An electrical signal is not transmitted by the kickdown switch turning on/off, and vehicle control is not affected.
