Hyundai Engine Control Units – ECU for Tucson, Santa Fe, Getz and i10

Hyundai Engine Control Unit – original used ECU and ECM modules

A Hyundai engine control unit ECU, also known as an ECM or engine computer, manages the operation of the engine and communicates with other electronic systems in the vehicle. Depending on the engine type and ECU generation, it may control fuel injection, ignition, fuel pressure, electronic throttle operation, turbocharger boost and selected emissions-related functions.

Auto24Parts offers original used Hyundai engine control units for different petrol and diesel applications. The catalogue includes control units manufactured by Bosch as well as other electronics manufacturers used by Hyundai. The safest way to select a replacement ECU is to compare all identification numbers shown on the original module.

How to choose the correct Hyundai engine control unit

The same Hyundai model may use several different ECU versions depending on engine type, power output, model year, transmission, emissions standard and vehicle configuration. For this reason, the model name or engine capacity alone is not sufficient to confirm compatibility.

Before ordering, compare:

• the complete Hyundai OEM part number,
• the electronics manufacturer's part number,
• all letters and digits shown after the main reference,
• the ECU family where available,
• hardware and software references,
• vehicle model and model year,
• engine capacity, power output and engine code,
• transmission and relevant vehicle configuration.

Part numbers may appear in different formats. For example, 39113-27295 may also be written as 3911327295, while Bosch 0281013422 may appear as 0 281 013 422. Both versions are useful when searching for the correct ECU.

Hyundai OEM numbers – 39110, 39101 and 39113

Many Hyundai engine control units use OEM references beginning with numbers such as 39110, 39101, 39113 or related 391xx sequences. These numbers are especially useful when identifying the exact engine computer fitted to the vehicle.

Examples found in the Auto24Parts catalogue include 39113-27295, 391012F400, 39110-02BA5, 39110-02425 and 39110-02PM0.

The complete number is important. A shared 39110 prefix does not mean that two ECUs are interchangeable.

Hyundai 2.0 CRDi – Bosch 0281013422 / 39113-27295

One of the available diesel control units is the Hyundai 2.0 CRDi Bosch 0281013422 / 39113-27295 ECU.

The Bosch reference can be written as 0281013422 or 0 281 013 422, while the Hyundai number can appear as 39113-27295 or 3911327295. Comparing both references provides much more accurate identification than searching only for “Hyundai 2.0 CRDi ECU”.

Hyundai Santa Fe – Bosch 0281016511 / 391012F400

For Hyundai Santa Fe, the catalogue includes the Bosch 0281016511 / Hyundai 391012F400 engine control unit.

The Bosch number may also be written as 0 281 016 511. When selecting this module, the Hyundai reference 391012F400 and Bosch reference 0281016511 should be checked together.

Hyundai Atos 1.1 – 39110-02BA5 / 9030930390F

For Hyundai Atos 1.1, Auto24Parts offers the 39110-02BA5 / 3911002BA5 / 9030930390F ECU.

This unit illustrates why all numbers on the label should be retained. The same part may be searched as 39110-02BA5, 3911002BA5, 9030930390F or 9 030 930 390F.

Hyundai Atos Prime 1.1 – 39110-02244 / 9030930465F

Another Atos application is the Hyundai Atos Prime 1.1 ECU 39110-02244 / 9030930465F / MXH4IS10.

Even within the Atos 1.1 range, different ECU numbers are used. Therefore, an Atos ECU should not be selected solely by vehicle model and engine capacity.

Hyundai Getz 1.1 – 39110-02425 / 9030930270F

For Hyundai Getz 1.1, an available unit is the 39110-02425 / 3911002425 / 9030930270F engine ECU.

The module also carries the designation TBF2IN11 A1. When replacing this ECU, the complete Hyundai number and additional electronics reference should be compared with the original unit.

Hyundai i10 – 39110-02PM0 / 9001040309KA

The catalogue also contains the Hyundai i10 ECU 39110-02PM0 / 3911002PM0 / 9001040309KA.

An additional identification on this unit is GPA-B41SFS0-5000. These additional references can be valuable when distinguishing between visually similar control units.

Why are all numbers on a Hyundai ECU label important?

A Hyundai engine computer may carry the vehicle manufacturer's OEM number together with one or more manufacturer, hardware, software or calibration references. For this reason, the safest method is to compare the entire label.

For example:

• 0281013422 / 39113-27295,
• 0281016511 / 391012F400,
• 39110-02BA5 / 9030930390F,
• 39110-02425 / 9030930270F,
• 39110-02PM0 / 9001040309KA.

Searching using both numbers creates a much more precise path from the label on the original ECU to the correct replacement product.

Bosch Hyundai diesel engine control units

Several Hyundai diesel applications use Bosch engine management systems. Examples available in Auto24Parts include 0281013422 and 0281016511.

More electronic modules from this manufacturer can be found in the Bosch automotive electronics section.

The Bosch name or the first digits of a Bosch reference are not sufficient to prove compatibility. The full Bosch number and Hyundai OEM reference should be checked together.

Common symptoms of a Hyundai ECU problem

A faulty engine control unit can cause various symptoms, although similar faults may also result from wiring, sensors, actuators, fuel-system problems or an incorrect power supply. Proper diagnosis should therefore be carried out before replacing the ECU.

• engine does not start,
• no diagnostic communication with the ECU,
• engine stalls or is difficult to restart,
• limp mode and reduced engine power,
• injector or ignition-control problems,
• incorrect throttle response,
• fuel-pressure or boost-control faults,
• CAN communication errors,
• fault codes that repeatedly return,
• internal ECU memory or electronics faults.

Before replacing the engine control unit, check the battery condition, ECU power supply, ground connections, fuses, relays, connectors and wiring harness. A stored fault code alone does not prove that the ECU itself is defective.

Used Hyundai ECU – does it require programming?

A standard used engine control unit normally contains data from its previous vehicle. Depending on the Hyundai model and ECU type, it may therefore require programming, resetting, adaptation or another preparation procedure before use in a different vehicle.

The exact process depends on the specific ECU. It should not be assumed that every Hyundai engine computer requires the same programming procedure.

VIRGIN / prepared Hyundai engine control unit

For selected control units, it may be possible to prepare the module as VIRGIN / reset or in another form suitable for subsequent adaptation.

After installation, programming, immobiliser synchronisation, coding or another vehicle-specific procedure may be required depending on the ECU and Hyundai model.

See the ECU preparation options page for more information about the different preparation methods.

Hyundai ECU cloning

Another possible solution is Hyundai ECU cloning. If the required data can be correctly read from the original control unit, it may be transferred to a compatible replacement ECU.

Depending on the module design, this may include EEPROM or FLASH data, configuration, VIN and immobiliser-related information required for the replacement unit to communicate correctly with the vehicle.

Cloning availability depends on the ECU type and condition of the original module. If the necessary data cannot be read, another preparation method may be required.

Hyundai and Kia engine control units

Hyundai and Kia belong to the same automotive group and some engines, electronic systems and control-unit families may be related. This does not mean that Hyundai and Kia ECUs are automatically interchangeable.

The complete OEM number, electronics manufacturer number, hardware, software and vehicle configuration must still be checked. Related units can be found in the Kia engine control unit category.

Hyundai engine control units by part number

Searching for a Hyundai ECU by part number is one of the most accurate ways to find the correct replacement module. Examples available in Auto24Parts include:

• 0281013422 / 39113-27295 – Hyundai 2.0 CRDi
• 0281016511 / 391012F400 – Hyundai Santa Fe
• 39110-02BA5 / 9030930390F – Hyundai Atos 1.1
• 39110-02244 / 9030930465F – Hyundai Atos Prime 1.1
• 39110-02425 / 9030930270F – Hyundai Getz 1.1
• 39110-02PM0 / 9001040309KA – Hyundai i10
