Error code C2402 in Hyundai and Kia – common fault in Mobis ABS pump

The error code C2402 "Pump motor electric circuit faulty" is very common in Hyundai Tucson , Kia Ceed, Venga, and Sportage vehicles. This error directly relates to the Mobis ABS/ESP pump (HECU – Hydraulic Electronic Control Unit) and, in practice, indicates an internal faulty module – not a problem with fuses or wiring.

This is one of the most common reports we receive. Even after checking wiring, fuses, or making temporary repairs, the error often returns. The cause lies within the ABS pump itself.

Symptoms of error code C2402

Recognizable complaints with Hyundai or Kia with this fault are:

• ABS / ESP / HAC / Auto Hold warning lights are on

• No ABS or ESP operation during braking

• In some cases no communication with the ABS control unit

• Brake system switches to emergency mode

Cause of the malfunction

The Hyundai and Kia ABS control units have a structural defect . Damage often occurs in:

• The power section of the pump

• Internal control electronics

Initially, the error code C2402 can be cleared, but over time the fault becomes permanent and the ABS system fails completely.

Does the pump always need to be replaced?

At branded dealerships, the entire ABS pump is usually replaced. This leads to high costs, sometimes running into several thousand euros .
Fortunately, in most cases this is not necessary: ​​repairing the original ABS module will fully restore operation at a much lower price.
