P0575 Code: Cruise Control Input Circuit

The P0575 code means the computer sees a fault in the signal from the cruise control switches, in the cruise control input circuit. Cruise control is disabled, and the rest of the vehicle works normally. A worn steering wheel clockspring is the most common cause.

What the P0575 code means

The cruise control switches, on the steering wheel or on a stalk, send their commands to the computer over one or more wires. Many manufacturers use a single line with a different resistance for each button, so the computer recognizes the pressed button by the voltage it measures.

The P0575 code means the computer sees a signal that does not correspond to any button, a signal that stays fixed as if a button were always pressed, or a signal that does not match the second control line. As a safety measure, it disables cruise control.

The most frequent cause is the clockspring in the steering wheel, which connects the buttons to the vehicle through a ribbon that wears out when the wheel turns. Buttons that are dirty or have had liquids spilled on them are another common cause.

Always begin with the simplest things: fuse, relay and connector. Then check power, ground and signal with the component connected (using back-probe pins), and finally the continuity of each wire to the computer. Replace the component only when all of that is good.

P0575 code symptoms

  • Cruise control that does not work.
  • Check engine light or cruise control light on.
  • Sometimes the horn or the steering wheel buttons stop working as well (clockspring).

Likely causes of the P0575 code

  1. Damaged steering wheel clockspring. The internal ribbon breaks with use.
  2. Steering wheel buttons that are dirty or damaged by spilled liquids.
  3. Control module connector with an intermittent contact.
  4. Brake switch, if it affects the cancel signal.

How to diagnose the P0575 code step by step

  1. Check the status of each button on the scan tool as you press it. Only the pressed button should change.
  2. Measure the switch resistance in each position and compare it with the manufacturer table.
  3. Check the clockspring if the horn, the airbag light or the steering wheel buttons also fail.
  4. Check the brake switch.

How to fix the P0575 code

  • Replace the clockspring or the steering wheel controls.
  • Clean the button contacts.
  • Repair the wiring.
  • Clear the code and test cruise control.

Technical reference data

  • Resistor ladder controls: each button gives a different voltage on the same line.
  • Reference values only: check the manufacturer data for your vehicle.

Brand-specific notes

When working on the steering wheel, disconnect the battery and wait a few minutes. The driver airbag could deploy.

Frequently asked questions about P0575

Can I drive with the P0575 code?
Yes. It only affects cruise control. The engine, brakes and the rest of the vehicle work normally, so it is not a safety problem on the road.
What is the clockspring?
It is a ribbon wound in the steering column that connects the airbag and the buttons to the vehicle even when the steering wheel turns. Once worn, it stops the buttons from working.
Is it dangerous to remove the steering wheel?
Yes, because of the airbag. Follow the manufacturer procedure, disconnect the battery and wait before touching anything.
How much does it cost to fix P0575?
Between $20 and $400. A cleaned contact or a repaired wire is cheap, while a clockspring or new steering wheel controls cost more.
What does the P0575 code mean?
The P0575 code is a generic OBD2 code for a fault in the cruise control input circuit. The computer does not accept the signal from the switches, so it turns the system off.
What is the most common cause of P0575?
A worn clockspring in the steering wheel. Dirty buttons and a loose connector come after that.
