Correct Vehicle & Where the Part Is Fitted
JD 5-DOOR REFERENCE
Reference vehicle: Ceed JD 5-door
The 2015-2018 facelift JD hatch is the principal listing application. A 2018 registration alone is not enough because third-generation CD cars also appeared in 2018—check the chassis generation.
LOCATION GUIDE
▼ Fitted behind the lower driver's dashboard trim, on the electric power-steering column assembly
Column-mounted MDPS controller
The controller receives steering and vehicle data, then commands the electric assist motor. It is not a hydraulic steering pump and is not the steering rack itself.

Critical Fitment Check — Read Before Ordering
For the lowest risk of a wrong order, the unit removed from your car should show A256399800 and preferably the same revision 4JDEC102 / 2.00. The plug shape, pin layout and bracket must also match the photographs. Send your VIN and a clear photo of your old label through eBay Messages if you need help.
| Vehicle / body style | Years | Status | Fitment requirement |
|---|---|---|---|
| Kia Ceed / cee'd JD 5-door hatchback | 2015-2018 | Primary listing application | JD chassis only; exact A256399800 label, connectors and bracket must match. |
| Kia Ceed SW / cee'd Sportswagon JD 5-door estate | 2015-2018 | Listed/cross-referenced application | Exact-number and visual match required. Do not rely on estate body style alone. |
| Kia Ceed JD estate van / commercial derivative | 2015-2018 | Verify before purchase | Some variants appear in the compatibility data; VIN and original label confirmation required. |
| Kia Pro cee'd JD 3-door | 2015-2018 | Cross-reference only | A256399800 is catalogued on some 3-door JD cars. Buy only after matching every identifier and the bracket. |
| Kia Ceed JD pre-facelift | 2012-2014 | Not guaranteed by this listing | The main number appears on some earlier JD vehicles, but revision/calibration can differ. VIN and old-unit label are mandatory. |
Known engine variants appearing in the JD compatibility data
Applications include selected 1.0 T-GDi, 1.4 MPI/CVVT, 1.4 CRDi, 1.6 GDi and 1.6 CRDi variants. Engine type does not prove compatibility; the steering module number and revision remain the deciding checks.
Will not fit
- Kia Ceed ED / first generation, generally 2006-2012.
- Kia Ceed CD / third generation, including 2018-on CD-platform vehicles.
- Kia Rio, Sportage, Soul, Venga, Optima or Hyundai models unless an authoritative VIN catalogue specifically returns this exact controller and all physical details match.
- Any Ceed JD using a different A256-series number, different connector arrangement, different bracket or incompatible software revision.
- Left-hand-drive applications unless the exact part number, bracket, connector and VIN catalogue all confirm compatibility.
Part Numbers & Technical Details
What This Module Controls
The MDPS/EPS control module is part of the column-assisted electric power-steering system. It processes steering input and vehicle-network information, calculates the required assistance and controls the electric motor on the steering-column assembly. Correct calibration and communication with the vehicle are essential for predictable steering assistance.
Typical warning signs
- Amber or red EPS / power-steering warning lamp.
- Heavy steering or complete loss of electrical assistance.
- Intermittent assistance, especially after starting or while manoeuvring.
- Uneven, over-light or inconsistent steering assistance.
- Stored EPS/MDPS fault codes or no communication with the steering controller.
- Steering-angle or calibration-related faults after column work.
Diagnose before replacement
- Low battery voltage, poor charging voltage or bad earths can mimic module failure.
- Check EPS fuses, wiring, connector condition and CAN communication.
- Read and record diagnostic trouble codes before disconnecting the old unit.
- Confirm whether the fault is in the module, torque/angle sensor, motor, column or mechanical steering components.
Why Choose an Original Used Component?
Fitting Guide, Required Tools & Repair Time
Typical required tools
- Professional diagnostic scan tool with Kia-compatible EPS/MDPS functions.
- Trim-removal tools, Phillips/flat drivers and Torx bits as required by the trim fitted.
- Metric socket and ratchet set, extensions and suitable spanners.
- Torque wrench and manufacturer repair information.
- Steering-wheel puller and SRS-safe equipment if column removal is required.
- Battery support/charger and electrical test equipment.
Typical workshop procedure
- Scan the existing EPS/MDPS system, record all fault codes and save steering-angle/calibration information where possible.
- Park with the road wheels straight, centre the steering wheel, switch off and isolate the battery in accordance with SRS safety procedures.
- Remove the driver's lower dash/knee trim and steering-column shrouds. Depending on access and workshop method, steering-wheel and column removal may be necessary.
- Locate the controller on the column-assisted EPS assembly. Inspect the wiring and connectors before condemning the module.
- Photograph and label all plugs, disconnect them carefully and remove the retaining fasteners/bracket without damaging the column or harness.
- Compare the old and replacement units side by side: A256399800, 4JDEC102, connector keying, pin layout and bracket must agree.
- Fit the replacement unit using the manufacturer's tightening specifications, route the wiring correctly and reassemble all trim/SRS components.
- Reconnect the battery and perform any required EPS type recognition, ASP/steering-angle calibration, fault clearing and system initialisation with a suitable diagnostic tool.
- Check warning lamps, steering effort, self-centring and full-lock operation, then complete a controlled road test and final diagnostic scan.
