If one of your Logitech pedals is not working correctly, swapping two pedal units can help you find out whether the fault is in the potentiometer or the wiring. You do not need a multimeter.

Why swap the pedals?

Each pedal unit has a potentiometer that measures pedal movement. The wiring carries its signal to the wheel.

By swapping a faulty pedal unit with a working one, while leaving the wiring in its original position, you can check which part the fault follows:

• The fault moves with the pedal unit: suspect its potentiometer.
• The fault stays with the original pedal input: suspect the wiring or its connections.

For example, if you swap a faulty brake unit with a working clutch unit, a potentiometer fault will now appear on the clutch input. A brake wiring fault will still appear on the brake input.

How to swap the pedal units

Disconnect the wheel’s power and USB, and unplug the pedals before starting.

1. Choose a faulty pedal and a working pedal. You will swap the complete pedal units, not just their foot pads.
2. Remove their foot pads and the housing’s bottom cover. The foot pads must come off before the pedal units can be removed.
3. Take a photo of the wiring connections. Check which unit is which—the factory markings underneath are usually A for accelerator, B for brake and C for clutch.
4. Disconnect the wires from both potentiometers. Use small pliers to grip the metal spade connectors. Do not pull on the wires.
5. Unscrew the two pedal units and exchange their positions. Leave the wiring in its original position.
6. Secure the units and reconnect the wires. Each unit now connects to the wiring at its new position. Use your photo to match the correct terminals, and refit any chassis ground connections you removed.
7. Refit the cover and foot pads, then reconnect and test. Check whether the original fault has moved to the other pedal input or stayed where it was.

Understanding the result

Fault moved? The potentiometer on the faulty pedal unit is the likely cause.

Fault stayed? The wiring or connections serving that input are the likely cause.

Result unclear? Contact us for help. PC software, including G HUB, can make the result harder to interpret; test on a compatible console if one is available.

After testing, disconnect everything and return the pedal units to their original positions.
