The C0572 OBD2 fault code relates to the Manufacturer Controlled DTC circuit. This is part of the vehicle's chassis control system. When a circuit failure occurs, the control module cannot properly monitor or regulate this system, which may affect braking, traction, stability, or suspension performance.

At AIscanAuto, we help drivers quickly identify OBD2 trouble codes, understand their root causes, and find the right fix — with AI-powered diagnostics that go beyond basic code reading.

Symptoms

• Chassis warning light
• Specific symptoms vary by manufacturer
• May be accompanied by other DTCs

Common Causes

• Faulty component — internal damage or wear affecting the Manufacturer Controlled DTC
• Wiring issues — broken, corroded, or chafed wires in the circuit
• Connector problems — loose, oxidized, or moisture-damaged pins
• a general circuit failure is detected — can result from wiring faults, connector issues, or component failure
• Control module fault — rare, but the chassis control module may have an internal fault

Step-by-Step Diagnosis

1. Scan with OBD2 tool — Confirm C0572 is active. Check for additional chassis DTCs.
2. Visual inspection — Examine the Manufacturer Controlled DTC wiring and connector for corrosion or damage.
3. Check voltage and ground — Use a multimeter to verify proper reference voltage.
4. Test component — Compare readings to factory specs. A stuck or erratic signal confirms failure.
5. Check for shorts/opens — Perform continuity tests on the wiring between the component and control module.

Repair & Solutions

• If the component is defective, replace the Manufacturer Controlled DTC with an OEM or quality aftermarket part.
• Repair any damaged wiring or connectors using proper methods.
• Clear the DTC with an OBD2 scanner and test drive to verify the code does not return.
• If the code persists after component replacement, inspect the control module connector or consider module testing.
