Under certain circumstances, simultaneous application of the brake and accelerator pedal (e.g., two footed driving) will result in the engine ECU returning the actuator to the idle position.

Upon release of the brake pedal and/or application of the accelerator pedal, there is a 1-2 second delay until the actuator moves to the new accelerator pedal input position. This delay is integrated in the ECU as a safety feature to provide smoother acceleration during actuator transition from idle and to minimize any sudden surges that might result from the release of the brake after simultaneous brake and accelerator application that may startle a driver. It is not subject to modification in the field.

A driver that simultaneously applies the brake and accelerator pedals may experience this scenario, especially when driving in stop and go traffic. In case of customer complaints, explain that this is a design characteristic incorporated in the engine management system as a safety feature.
