Daewoo Engine Control Units – ECU by Part Number

Daewoo Engine ECU – Engine Computers for Matiz, Lanos, Nexia, Nubira and Leganza

A Daewoo engine control unit, also known as ECU, ECM or engine computer, manages the operation of the engine according to information received from sensors and other vehicle systems.

Depending on the engine and ECU generation, the controller can manage fuel injection, ignition, idle operation, emissions-related functions and communication with other electronic systems.

Daewoo engine computers can be searched using terms such as:

• Daewoo ECU,
• Daewoo engine control unit,
• Daewoo engine computer,
• Daewoo ECM,
• Daewoo Matiz ECU,
• Daewoo Lanos ECU,
• Daewoo Nexia ECU,
• Daewoo Nubira ECU,
• Daewoo Leganza engine computer.

For accurate identification, however, the complete numbers printed on the original ECU are more important than the model name alone.

How to choose the correct Daewoo ECU

The same Daewoo model can use several different engine controllers depending on engine version, production period and electronic configuration.

Before ordering, compare:

• complete ECU manufacturer number,
• complete Daewoo / OEM reference,
• all suffix letters,
• short calibration or identification codes,
• engine version,
• vehicle model and production year as supporting information.

Similar housing, the same connector or the same vehicle model does not automatically mean that two ECUs are interchangeable.

Daewoo Matiz ECU – Siemens K115000010...

One of the most important Daewoo ECU families in the catalogue is used in the Matiz 0.8.

Examples include Siemens numbers such as:

• K115000010E,
• K115000010F,
• K115000010G.

These controllers may share the Daewoo number 96259124, but the final Siemens letter should still be checked carefully.

Daewoo Matiz 0.8 – K115000010F / 96259124 / 2S

A confirmed product is the Daewoo Matiz 0.8 ECU K115000010F / 96259124 / 2S.

The main identification numbers are:

• K115000010F,
• 96259124,
• 2S.

When searching for a replacement, it is better to compare the complete Siemens reference rather than using only 96259124.

K115000010E, K115000010F and K115000010G – why the final letter matters

The Daewoo Matiz catalogue contains several very similar Siemens references:

• K115000010E,
• K115000010F,
• K115000010G.

The common number family does not automatically confirm compatibility. The complete label should be compared before ordering.

Daewoo Matiz 1.0 – S010013001 / 96291049

Daewoo Matiz was also fitted with other ECU families. One catalogue example for the 1.0 version uses:

• S010013001,
• 96291049,
• 4U.

This is a completely different controller family from the K115000010... units used in selected 0.8 versions.

Daewoo Lanos ECU – 16238981 / 16246909

The catalogue includes the Daewoo Lanos engine ECU 16238981 / 16246909 / CKAK / 1E.

Important references:

• 16238981,
• 16246909,
• CKAK,
• 1E.

The short code CKAK is part of the identification and should not be ignored when comparing the original controller.

Daewoo Nubira – 16238981 / 16246949 / CFWY

Another controller uses the same 16238981 main reference but a different second number.

The Daewoo Nubira ECU 16238981 / 16246949 / CFWY / C4 carries:

• 16238981,
• 16246949,
• CFWY,
• C4.

16238981 Lanos and Nubira ECUs are not identified by one number alone

This is an especially useful example when selecting Daewoo electronics.

Compare:

• Lanos: 16238981 / 16246909 / CKAK,
• Nubira: 16238981 / 16246949 / CFWY.

Both units contain 16238981, but their additional references are different. This is why the complete set of numbers should be checked rather than relying on a single shared number.

Daewoo Nubira 1.6 – S010016006 D1 / 96378045

Another Nubira ECU family uses:

• S010016006 D1,
• 96378045,
• 1AKN,
• U6.

This controller belongs to a different electronics family from the 16238981 / 16246949 unit.

Daewoo Leganza 2.0 – 16245887 / 09367489

For Daewoo Leganza, one of the confirmed units is the Leganza 2.0 ECU 16245887 / 09367489 / 3B.

The relevant numbers are:

• 16245887,
• 09367489,
• 3B.

Searching with both main references gives a much more precise result than using only “Daewoo Leganza ECU”.

Daewoo Nexia ECU – Delco 16199550...

Daewoo Nexia and selected Espero versions use several Delco controllers from the 16199550... family.

Examples include:

• 16199550 DM / 16238149 / BUPW,
• 16199550 HG / BPCU,
• 16199550 SS / BPHM.

The final two letters are part of the complete reference and should always be retained.

Daewoo Nexia 1.5 – 16199550 DM / 16238149 / BUPW

A confirmed example is the Daewoo Nexia 1.5 8V ECU 16199550 DM / 16238149 / BUPW.

Important references:

• 16199550 DM,
• 16199550DM,
• 16238149,
• BUPW.

Both spaced and compact forms of the number can be useful search terms.

Daewoo Nexia 1.5 – 16199550 HG / BPCU

The catalogue also includes the Daewoo Nexia ECU 16199550 HG / BPCU.

Although the main number is similar to 16199550 DM, the suffix is different. These references should not automatically be treated as interchangeable.

Daewoo Espero / Nexia – 16199550 SS / BPHM

Another version is the Daewoo Espero / Nexia 1.5 ECU 16199550 SS / BPHM.

Compare the three examples:

• 16199550 DM,
• 16199550 HG,
• 16199550 SS.

The suffix forms part of the complete ECU identification.

Daewoo Nexia / Espero 2.0 – 16208045 NA

The catalogue also includes the Daewoo Nexia / Espero 2.0 ECU 16208045 NA / 864659S3643099 / BNRN.

Its main references include:

• 16208045 NA,
• 16208045NA,
• 864659S3643099,
• BNRN.

Nexia 16208045 NA and 16208045 NB

Very similar references can also have different final letters. For example, the catalogue contains a Nexia controller with 16208045 NB / BSWH.

Therefore:

• 16208045 NA,
• 16208045 NB

should not be assumed to represent the same ECU version.

Siemens, Delco and other Daewoo ECU manufacturers

Daewoo used engine management electronics from several suppliers depending on model and engine generation.

Important families in the catalogue include:

• Siemens K115... controllers,
• Delco 16199550... and 162... families,
• Kemsco S010... controllers,
• other original OEM engine control units.

Manufacturer family names are useful for searching, but compatibility should always be verified using the complete reference.

Common symptoms of a Daewoo ECU problem

Possible symptoms may include:

• engine does not start,
• intermittent no-start condition,
• engine stalls unexpectedly,
• unstable engine operation,
• loss of communication with the ECU,
• incorrect control of selected engine circuits,
• internal ECU fault codes,
• immobiliser or starting-related problems.

These symptoms do not automatically prove that the engine computer itself is faulty.

No communication with the Daewoo ECU

If diagnostic equipment cannot communicate with the engine controller, check:

• ECU power supply,
• ground connections,
• fuses and relays,
• connectors and pins,
• wiring between the ECU and diagnostic system,
• corrosion or water damage.

A vehicle-side electrical fault can cause the same symptom as a failed ECU.

Does a used Daewoo ECU require programming?

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

Depending on the ECU, available options may include:

• a locked used controller,
• an unlocked controller ready for programming,
• reset or preparation for reuse,
• immobiliser-related preparation,
• data transfer from the original ECU,
• cloning where supported,
• other controller-specific preparation options.

The correct method depends on the exact ECU and vehicle. See ECU preparation options for more information.

Can a Daewoo ECU be cloned?

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

The possibility depends on the electronics type and condition of the original controller. A severely damaged module may not always provide readable data.
