Description:

This error code indicates that the voltage at the signal input of channel 1 of the accelerator pedal potentiometer exceeds 4.5 volts. This high voltage suggests a problem with the signal lead or the ground connection of the potentiometer.

Reaction:

The control software will limit or disable the function of the accelerator pedal potentiometer, potentially resulting in reduced responsiveness or complete non-functionality of the accelerator pedal.

Recommendations:

Inspect Signal and Ground Connections:

• Check the wiring for the signal lead and ground connection of the potentiometer for any signs of damage, loose connections, or corrosion. Repair or replace as necessary.

Test Potentiometer Output:

• Use a multimeter to measure the voltage at channel 1. If it is consistently above 4.5 volts, the potentiometer may be faulty and require replacement.

Verify Ground Integrity:

• Ensure that the ground connection for the potentiometer is secure and free of corrosion. A poor ground can cause incorrect voltage readings.

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.
