Description:

This error code indicates that the signal from the accelerator pedal potentiometer is out of the valid range. The control system cannot properly interpret the signal, and operators are advised to use the hand throttle instead and rectify the fault.

Reaction:

The control software will disable the function of the accelerator pedal potentiometer entirely, resulting in no accelerator response.

Recommendations:

Inspect Potentiometer and Connections:

• Check the potentiometer and its connections for any signs of damage, loose connections, or corrosion. Repair or replace as necessary.

Test Potentiometer Signal Range:

• Use a multimeter to measure the signal range of the potentiometer. Ensure the output falls within the expected range specified by the manufacturer.

Use Hand Throttle Temporarily:

• Use the hand throttle as a temporary measure to maintain vehicle operation while diagnosing the potentiometer issue.

Update Control Software:

• Confirm that the control software is up-to-date. Firmware updates might include improvements in handling potentiometer signals.

Consult Manufacturer Support:

• If the issue persists after checking connections and testing the potentiometer, consult technical support or the manufacturer for further diagnostics and potential replacement parts.

Monitor System Performance:

• After taking corrective actions, monitor the system to ensure that the error does not recur. Pay attention to any irregularities in accelerator response.

Note:

Regular maintenance and inspection of the accelerator pedal potentiometer and its connections are crucial to prevent future occurrences of this issue. Environmental factors like moisture or extreme temperatures can also impact performance and should be considered during troubleshooting.
