OIC 003032.04 – Sensor Unit for Right Brake Pedal, Voltage Too Low

OIC 003032.04 (OIC 3032.04)

Code: 003032.04

Shortcode: 3032.04


This error code indicates that the voltage at the signal input of the right brake pedal potentiometer is less than 0.25 volts. This low voltage suggests a problem with the signal lead or the potentiometer’s supply voltage.


The control software may function in a limited capacity or not at all, affecting the brake pedal sensor unit.


Inspect Signal and Power Connections:

  • Check the wiring for the signal lead and power supply to the right brake pedal 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 the signal input. If it consistently reads below 0.25 volts, the potentiometer may be faulty and require replacement.

Verify Power Supply:

  • Ensure that the potentiometer is receiving the correct supply voltage. A weak or intermittent power supply can cause low voltage readings.

Update Control Software:

  • Ensure that the control software is updated to the latest version. Firmware updates might include improvements in handling potentiometer signals.

Consult Manufacturer Support:

  • If the issue persists, 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 the error does not recur and that the brake pedal functions correctly.


Maintaining a stable power supply and proper connections is crucial for the reliable operation of the brake pedal potentiometer.
