DI_a187_pedalMisapplication

Obstacle detected - Acceleration reduced

What does the DI_a187_pedalMisapplication alert mean?

The drive interface (DI) electronic control unit (ECU) reduces acceleration because it detects a potential pedal misapplication (when the user presses the accelerator in Drive or Reverse when they meant to press the brake).

What you'll see in your Tesla

  • Obstacle detected - Acceleration reduced
  • Release accelerator pedal

What triggers it

The DI ECU detects that the accelerator pedal was pressed past the set threshold and the driver assistance system (DAS) detects an object with a high enough level of confidence.

When it clears

Either the DAS ECU no longer detects an object, or the user releases the accelerator pedal and then presses it again to override the alert.

Potential impact

The DI ECU limits torque/acceleration.

Affected models

Cybertruck Model 3 2017-2023 Model 3 2024+ Model S 2021+ Model X 2021+ Model Y Model Y 2025+ Semitruck
