ACCELERATOR PEDAL, KICKDOWN SWITCH [SKYACTIV-D 2.2]

id0113z7189000

Purpose, Function

• The driver's intentions are transmitted to the PCM via the accelerator pedal.

Kickdown switch (ATX)^*

• 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.

• For the APP sensor, refer to CONTROL SYSTEM. (See ACCELERATOR PEDAL POSITION (APP) SENSOR [SKYACTIV-D 2.2].)

• A load can be felt while the accelerator pedal is being depressed and when it is further depressed the kickdown switch turns on.

• 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.
