SsangYong Engine Control Units – ECU / ECM

SsangYong Engine ECU – Engine Computers by Part Number

A SsangYong engine control unit is the electronic controller responsible for managing the operation of the engine. Depending on the engine-management system, the ECU communicates with fuel-injection components, sensors and other electronic modules in the vehicle.

These parts may also be searched for as:

• SsangYong ECU,
• SsangYong ECM,
• SsangYong engine computer,
• SsangYong engine control module,
• SsangYong diesel ECU,
• SsangYong XDI ECU.

The exact part number on the original controller is more important than the general name used to describe the module.

How to choose the correct SsangYong ECU

The same SsangYong model can use different ECU versions. A controller should therefore not be selected only by vehicle model, engine capacity or physical appearance.

Before ordering, compare:

• complete SsangYong / OEM part number,
• controller manufacturer number,
• complete R0411C... or R0412C... designation,
• Delphi number where present,
• additional short identification codes,
• vehicle model and engine version as supporting information.

Similar housings and identical connectors do not automatically mean that two ECUs are interchangeable.

SsangYong Kyron – A6645408032 / R0411C044A / 28036682

One confirmed example is the SsangYong Kyron ECU A6645408032 / R0411C044A / 28036682.

Important references include:

• A6645408032,
• A664 540 80 32,
• R0411C044A,
• 28036682.

When searching for this controller, using both the A664... number and R0411C044A gives more precise results than searching only for “SsangYong Kyron ECU”.

SsangYong Rodius – A6655404432 / R0412C019A

The catalogue also includes the SsangYong Rodius ECU R0412C019A / A6655404432 / 28075135.

Its main references are:

• R0412C019A,
• A665 540 44 32,
• A6655404432,
• 28075135.

This controller is catalogued for selected SsangYong Rodius vehicles from approximately 2006–2009. Exact compatibility should still be confirmed from the original ECU label.

SsangYong Actyon – A6645406532 / R0412C008B

Another available controller is the SsangYong Actyon ECU A6645406532 / R0412C008B / 28075098.

The important identifiers are:

• A664 540 65 32,
• A6645406532,
• 28075098,
• R0412C008B.

The similar A664 prefix used on other SsangYong ECUs does not indicate interchangeability. The complete number must be checked.

SsangYong 2.0 XDI – Delphi DCM3.7AP

A different ECU family is represented by the SsangYong 2.0 XDI Delphi 28283968 / 6715400032 / DCM3.7AP engine controller.

The unit carries:

• Delphi 28283968,
• 671 540 00 32,
• 6715400032,
• DCM3.7AP.

The product is catalogued for a SsangYong 2.0 XDI application from around 2011.

Delphi DCM3.7AP – use the complete number

DCM3.7AP identifies a controller family rather than one universal ECU. For accurate identification, it should be combined with the Delphi and OEM references.

For the SsangYong example above, the useful combination is:

28283968 / 6715400032 / DCM3.7AP

Searching only for “DCM3.7AP ECU” may return controllers intended for different vehicles or software versions.

SsangYong Rexton 2.7 CDI – A6655400132

The SsangYong Rexton 2.7 CDI is particularly important when explaining why the complete ECU label must be checked.

Several controllers can share the basic number:

A6655400132 / A665 540 01 32

while having different R0411C versions and additional references.

Rexton A6655400132 / R0411C025J / 28019193

One version is the SsangYong Rexton 2.7 CDI ECU A6655400132 / R0411C025J / 28019193 / FBMN.

• A6655400132,
• R0411C025J,
• 28019193,
• FBMN.

Rexton A6655400132 / R0411C025H / 28014130

Another version is the SsangYong Rexton ECU A6655400132 / R0411C025H / 28014130 / FBCH.

• A6655400132,
• R0411C025H,
• 28014130,
• FBCH.

Rexton A6655400132 / R0411C025D / 12249841

A further variant is the SsangYong Rexton 2.7 CDI ECU A6655400132 / R0411C025D / 12249841 / DZLC.

• A6655400132,
• R0411C025D,
• 12249841,
• DZLC.

R0411C025D, R0411C025H and R0411C025J are different references

Compare:

• R0411C025D,
• R0411C025H,
• R0411C025J.

Although these references are very similar and can share the OEM number A6655400132, the suffix letter and additional identification numbers differ.

Do not assume that these ECU versions are interchangeable without verifying the complete original module identification.

A664, A665 and 671 SsangYong ECU numbers

Important SsangYong ECU references found in the catalogue include:

• A6645408032,
• A6645406532,
• A6655404432,
• A6655400132,
• 6715400032.

These numbers are useful search references, but the complete second controller number should also be checked whenever available.

Part numbers with and without spaces

The same SsangYong ECU number can be written in several ways:

• A664 540 80 32 = A6645408032,
• A664 540 65 32 = A6645406532,
• A665 540 44 32 = A6655404432,
• A665 540 01 32 = A6655400132,
• 671 540 00 32 = 6715400032.

Both formats are worth using when searching for an ECU online.

Common symptoms of a SsangYong ECU problem

Possible symptoms may include:

• engine will not start,
• loss of communication with the engine ECU,
• intermittent engine shutdown,
• reduced engine power,
• limp mode,
• irregular engine operation,
• internal ECU fault codes,
• missing control of a specific circuit.

These symptoms do not automatically confirm that the engine control unit itself is faulty.

No communication with the SsangYong ECU

Before replacing the controller, it is worth checking:

• ECU power supply,
• ground connections,
• fuses and relays,
• connector condition,
• damaged or corroded pins,
• vehicle communication wiring,
• battery voltage.

A vehicle-side electrical problem can cause the same no-communication symptom as an internally damaged ECU.

Does a used SsangYong ECU require programming?

There is no single replacement procedure for every SsangYong engine controller.

Depending on the exact ECU, possible preparation methods may include:

• programming or adaptation,
• preparation for reuse,
• immobiliser synchronisation,
• transfer of data from the original ECU,
• cloning,
• other controller-specific preparation methods.

The required procedure should always be confirmed for the exact ECU number rather than assumed from the vehicle model alone.

See our ECU preparation options for more information.

Can a SsangYong ECU be cloned?

For selected engine controllers, it may be possible to transfer the required data from the original ECU to a compatible replacement unit.

The possibility of cloning depends on the controller type and the condition of the original unit. If the damaged ECU cannot be read, another preparation method may be necessary.

How to search for a SsangYong ECU by part number

Useful long-tail search combinations include:

• SsangYong Kyron ECU A6645408032 R0411C044A,
• SsangYong Rodius ECU A6655404432 R0412C019A,
• SsangYong Actyon ECU A6645406532 R0412C008B,
• SsangYong 2.0 XDI ECU 28283968 6715400032 DCM3.7AP,
• SsangYong Rexton ECU A6655400132 R0411C025J,
• Rexton ECU A6655400132 R0411C025H,
• Rexton 2.7 CDI ECU A6655400132 R0411C025D.

Combining the vehicle model with two or more references from the original ECU label usually gives much more precise search results.

How to confirm compatibility before ordering

If you are unsure which SsangYong engine controller is correct, contact Auto24Parts.

For compatibility verification, send:

• a clear photo of the complete original ECU label,
• all A664..., A665... or 671... numbers,
• R0411C... or R0412C... reference,
• Delphi number where present,
• all additional letters and identification codes,
• vehicle model,
• production year,
• engine version.

The complete combination of numbers from the original ECU is the safest basis for selecting a replacement controller.
