C004F code meaning
ABS Control Module Over Temperature
What C004F means
Set when the ABS/ESC control module or its integrated pump motor reaches a temperature above the safe operating limit. Repeated or prolonged pressure modulation, for example during long downhill ABS use, frequent stability interventions or an electrical fault that keeps the pump running, heats the hydraulic unit and its motor; the module monitors an internal temperature model or sensor and stores this code to protect the hardware. It temporarily disables ABS, traction and stability control until the unit cools, then restores them. A persistent over-temperature points to a seized pump, a stuck valve causing continuous pumping or a control fault. Base braking remains and the ABS warning lamp is set while the function is suspended. The entry follows the SAE J2012 generic definition and ABS hydraulic unit thermal protection.

- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C004F
- ABS and stability control temporarily disabled
- Function returns after cooling
- ABS warning lamp on during the event
Common causes of C004F
- Most likelyStuck valve causing continuous pump run
- PossiblePump motor seizing or high friction
- Less likelyProlonged heavy ABS/ESC use
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| 0 | Generic code: it means the same on every make (SAE standard). |
| 4F | The exact fault in that area. |
What to do next
- Note C004F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C004F
What does C004F mean?
C004F means "ABS Control Module Over Temperature". Set when the ABS/ESC control module or its integrated pump motor reaches a temperature above the safe operating limit. It is a generic code, so it means the same on every make.
Is it safe to drive with C004F?
Drive gently and only to a workshop. With C004F the car can go into limp mode (reduced power) to protect itself.
Will C004F fail an emissions test?
C004F is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C004F to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will C004F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
