Description:

This diagnostic trouble code (DTC) is triggered when the control software detects a discrepancy between the output signals of the accelerator pedal potentiometer. Specifically, the voltage at channel 1 must be exactly double the voltage at channel 2. When this condition is detected, it indicates that the voltages are not in the correct ratio, and the DTC is generated.

Reaction:

• The control software will either limit or completely disable the function of the accelerator pedal potentiometer.
• This DTC will also trigger a corresponding code in the OIC (Operator Information Center) control software, indicating an issue with the accelerator pedal.

Recommendations:

Check Accelerator Pedal Potentiometer:

• Inspect the potentiometer for any physical damage or wear that could cause incorrect voltage readings.
• Ensure the potentiometer is properly installed and calibrated.

Inspect Wiring and Connections:

• Check all wiring and connectors between the accelerator pedal and the control unit for any signs of damage, corrosion, or loose connections.
• Repair or replace any damaged wires or connectors.

Verify Voltage Outputs:

• Use a multimeter to measure the voltages at channel 1 and channel 2 of the accelerator pedal potentiometer.
• Ensure that the voltage at channel 1 is exactly double the voltage at channel 2. If not, replace the potentiometer.

Update Control Software:

• Ensure that the control software is up-to-date with the latest version provided by the manufacturer. Updates may include improvements or fixes for detecting and handling potentiometer signals.

Consult Technical Support:

• If the problem persists after performing the above checks, consult technical support for further diagnostic procedures or to determine if there is an underlying issue with the control software or hardware.

Note:

• In some cases, environmental factors such as extreme temperatures or humidity can affect the performance of the accelerator pedal potentiometer. Ensure that the equipment is operating within the recommended environmental conditions.
• Regular maintenance and inspection of the accelerator pedal and its components can prevent the occurrence of this DTC.
