Drive by wire

The DBW module is made on a separate processor that only deals with throttle control. If an error is detected, the electronic throttle module will disable the throttle.

Settings

Throttle max limit

Limits the maximum throttle position

Throttle min limit

Limits minimum throttle position

RPM ​​limit

Limits throttle opening near the RPM limit. The heading of the table shows the RPM relative to the RPM limit. 0 is the RPM limit.

Idle controller range

Sets the throttle open percentage, which corresponds to 100% of the Idle controller position. If set to 0, the idle speed controller is disconnected from the throttle and a separate IAC can be connected.

Non-linearity

Sets the non-linearity of the throttle response. The higher the number, the smoother the throttle response at low openings.

Speed

Sets the reaction speed of the throttle.

Second pedal sensor

Sets the calibration of the second pedal sensor. Select analog sensor input in input settings

For calibration:

  • Release the pedal. Set the 0% voltage
  • Press the pedal all the way down. Set the 100% voltage

Values ​​may change slightly after saving due to internal rounding of numbers.

Calibration

Opens the DBW driver configuration window

Adaptation

Starts the throttle adaptation procedure. The adaptation measures the range of movement of the throttle, as well as the force of the return springs, adjusting the algorithm for a specific throttle.

Damper

Designed to smoothly close the damper in the near-zero range. When the throttle closes below the threshold, the speed of the throttle movement is reduced.

PID

Adjusts the throttle controller PID

Status indicators

Communication OK

Communication with throttle control module is established

Configuration OK

Throttle is configured correctly

Calibration error

Throttle start position is out of calibration. When this error is detected, the throttle is disabled.

Causes: Incorrect calibration or throttle plate stuck.

Throttle sensor errors

Intermittent false readings from the throttle position sensors. Check the wiring and connectors as well as the signal from the sensors with an oscilloscope.

Throttle sensor failure

Critical errors in the readings of the throttle position sensors. When this error is detected, the throttle is disabled. Check the wiring and connectors as well as the signal from the sensors with an oscilloscope.

Positioning error

The throttle cannot set the target position. When this error is detected, the throttle is disabled. Causes: Incorrect calibration or throttle plate stuck.

Power driver failure

The throttle motor power IC detected an error and shut down. When this error is detected, the throttle is disabled. Check wiring and connectors. Look for a short circuit.

Throttle sensor errors

Intermittent false readings from pedal position sensors. Check the wiring and connectors as well as the signal from the sensors with an oscilloscope.

Throttle sensor failure

Critical errors in the readings of the pedal position sensors. When this error is detected, the throttle is disabled. Check the wiring and connectors as well as the signal from the sensors with an oscilloscope.
