A failing Engine Control Module (ECM), often referred to as the Engine Control Unit (ECU) or Powertrain Control Module (PCM), can be the root cause of many performance issues in your Hyundai Tucson. Understanding the specifics of your module, such as the Bosch part number 0281015440 and the Hyundai OE part number 39113-27297, is the first step toward a successful replacement.
Key Information and Part Numbers
This guide focuses on a specific ECU variant commonly found in the Hyundai Tucson 2.0L CRDi (Diesel) models, typically within the JM generation (approx. 2004-2010).
| Part Type | Part Number | Manufacturer | Notes |
| Bosch Part No. | 0281015440 | Bosch | Primary Manufacturer's Part Number. |
| Hyundai OE No. | 39113-27297 | Hyundai/Kia | Original Equipment Manufacturer Part Number. |
| Bosch Serial No. | 1039S28215 | Bosch | A detailed batch/serial number for tracking. |
| ECU Type | EDC16C39 | Bosch | The specific family of control unit (Electronic Diesel Control). |
Crucial Note: The part numbers 1039S28215 and F0JM0T2EIH1S are typically internal serial numbers, software versions, or hardware IDs and should be used only for cross-referencing, with the 0281015440 and 39113-27297 being the critical replacement numbers.
Does the Replacement ECU Need Programming?
Yes, in most cases, a new or used/virgin replacement ECU will require programming.
An ECU is linked to your vehicle's immobilizer system (which includes the keys and the immobilizer control unit/BCM). A locked or virgin replacement ECU must be coded to your specific vehicle's VIN (Vehicle Identification Number) and sync with the immobilizer to allow the engine to start.
Here are the typical replacement options:
| Option | Programming Required? | Detail |
| New, Locked ECU | Yes (Required) | Must be coded and synchronized to the immobilizer. |
| Virgin ECU | Yes (Required) | Has no vehicle data and must be programmed and synced. |
| Cloned/Plug & Play ECU | No (Usually) | Your original software and immobilizer data are transferred to the replacement unit. This is often the easiest option. |
| Immo-OFF ECU | No (Usually) | Modified to bypass the immobilizer check (often for racing/off-road use only; check local laws). |
Recommendation: To ensure a smooth process, look for a replacement option that offers ECU Clone (Plug & Play) service, or be prepared to use a professional auto locksmith or dealership for programming/coding after installation.
Compatibility Table (Hyundai Tucson 2.0 CRDi)

Frequently Asked Questions (FAQ)
Q: What is the difference between an ECM and an ECU?
A: ECM (Engine Control Module) is a precise term for the unit that controls the engine. ECU (Electronic Control Unit) is a generic term for any electronic module (like ABS, BCM, TCM). In practice, they are often used interchangeably for the engine computer.
Q: How do I know if my Hyundai Tucson ECU is faulty?
A: Common symptoms include engine no-start (especially if the immobilizer light is active), persistent Check Engine Light (CEL) codes that won't clear, intermittent stalling, or complete loss of communication with diagnostic tools.
Q: Can I replace the ECU myself?
A: While the physical replacement is straightforward, the programming and coding are highly specialized and require professional diagnostic tools. It is strongly recommended to use a qualified mechanic or auto-electrician for the complete replacement process.
