• C0040
• C0041
The car's computer that helps with braking is getting too hot.
The ABS control module monitors the temperature of its components to ensure proper operation. If it detects an over-temperature condition, it triggers the C004F code.
The C004F code indicates that the Anti-lock Braking System (ABS) control module has detected a temperature that exceeds the safe operating range. This could be due to excessive braking, an electrical fault, or a failure within the module itself.

• Avoid excessive braking
• Regularly inspect ABS components
• Ensure proper ventilation around the ABS module
ABS System Issue
• Drive cautiously and avoid hard braking
• Have the vehicle inspected by a professional
Check with the vehicle manufacturer for specific warranty coverage related to ABS components.
This code has been associated with overheating issues in ABS systems, particularly in older vehicles with high mileage.
Moderate – While the vehicle may still be drivable, reduced braking performance can be a safety concern.
Driving with a malfunctioning ABS system can increase stopping distances and risk of skidding.
• Vehicle at operating temperature
• Perform a series of braking tests
The ABS control module is typically located near the brake master cylinder or within the engine compartment.
Q: Can I drive with the C004F code?
A: It's possible, but not recommended as the ABS system may not function properly, increasing stopping distances.
Q: How do I reset the ABS warning light?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
