id051400328400

Construction

• There is one pair of up and down switches on both the left and right sides of the steering wheel.
• The down switch is built into the audio control and cruise control switches. (For vehicles without cruise control, there is only a down switch.)

Operation

Sending of up/down-shift request signals

  • The TCM detects an up/down-shift request signal according to the voltage applied to terminal 2AF.
  • When the up or down switch is operated, the resistor built into the down switch changes the voltage applied to TCM terminal 2AF.
  • The TCM controls upshifting or downshifting based on this change in voltage.
