Chevrolet ECU & Engine Control Modules – GM, 5WY and Bosch
Chevrolet Engine Control Units: Choosing by Part Number
At Auto24Parts you will find used original engine control units for Chevrolet cars, including the Spark, Aveo, Cruze, Lacetti, Matiz and Captiva models, inspected and tested before sale. Control units for other makes and models can be found among all engine control units.
What matters when choosing is the complete part number from the label, for example 96436779 or 25191187, not just the model and year. If you are not sure, send us a photo of the label on the original control unit and we will help you check compatibility.
Engine control units may be offered in several preparation variants, for example locked, unlocked or full set. We describe them on the ECU preparation options page.
List of products
Chevrolet Engine Control Units: ECU, ECM and Engine Computer
An engine control unit, also called an ECU, ECM or engine computer, is an electronic module that manages engine operation based on signals from sensors. When it fails, the car may not start, the engine warning light may come on and the diagnostic tester may be unable to connect to the control unit.
How to choose a control unit for a Chevrolet by part number
Model, year and engine capacity are often not enough, because the same model can come with different versions of the control unit. Before buying, compare:
- the part number, for example 96436779, 25191187 or 96419331,
- the control unit manufacturer's number, for example 5WY1W20A, 5WY5968C or 0281014296,
- the code at the end of the designation, for example XAJZ or AAGR,
- the model and engine designation given in the listing, for example Aveo 1.4.
A similar housing and identical connectors do not confirm that two control units are compatible.

Chevrolet control units by part number
Some listings do not state the model, so choosing is based on the number. Examples:
- Chevrolet control unit, number 12574976,
- Chevrolet control unit, number 25184173,
- Chevrolet control unit, number 16144288,
- Chevrolet Hyundai control unit, number 96435547.
Our range changes regularly and not every listing states the year and the engine, so compatibility is determined by the number on the original control unit.
Engine control unit variants
Engine control units may be offered in several variants: locked (with data from the previous vehicle), unlocked (for example Virgin, with a PIN code or CAR PASS, IMMO OFF or Plug and Play) or as a full set. Whether a unit can be prepared depends on the full part number, the manufacturer and the immobiliser system. We describe the details on the ECU preparation options page.
Used original control unit: condition and inspection
We sell used original control units, not new parts. Every unit is inspected before sale, and you can compare the numbers in the listing with the label on your own control unit.
