P0575 Fault Code

Cruise Control Input Circuit

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0575 code refers to issues within the cruise control input circuit. This circuit is responsible for sending signals between the cruise control system and the engine control module (ECM). When the system detects a problem with this communication, it triggers the P0575 fault code, indicating that the cruise control may not function correctly.

What are the symptoms of the P0575 code?

Vehicle symptoms associated with a P0575 code may include:

• Inability to activate or deactivate cruise control
• Cruise control system disengaging unexpectedly
• Warning lights illuminated on the dashboard
• Erratic speed control when cruise control is engaged

What causes the P0575 code?

Common causes for the P0575 code include:

• Faulty cruise control switch or pedal
• Damaged or corroded wiring and connectors in the input circuit
• Malfunctioning brake light switch
• Issues with the engine control module (ECM) itself
• Blown fuses related to the cruise control system

How to fix P0575?

To resolve the P0575 fault code, the following steps should be taken:

1. Inspect the cruise control switch and wiring for any visible damage or corrosion.
2. Test the brake light switch to ensure it is functioning properly.
3. Check for any blown fuses that may affect the cruise control system.
4. Use a multimeter to test the continuity of the input circuit.
5. If wiring or connectors are damaged, repair or replace them as needed.
6. If no mechanical faults are found, consider reprogramming or replacing the ECM if it is suspected to be faulty.
