A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

Important: Depending on the ECU type and vehicle model, not all of the options listed below may be available.
To select the correct option for your vehicle and ECU, please contact us before purchasing:
contact@auto24parts.com
1. Locked
This option is intended for professional workshops with the required specialist equipment and technical knowledge.
The ECU has been removed from a vehicle intended for recycling and still contains the immobilizer data and other information from the previous vehicle. Before it can be used in another car, it must be unlocked and then programmed using specialist automotive diagnostic equipment.
2. Unlocked
Several preparation methods may be available. The possible options depend on the ECU type, vehicle model and immobilizer system. Please contact us before purchasing, as some preparation methods are not available for every ECU.
Our electronics specialists can prepare the ECU in one of the following ways:
a) ECU with PIN code (Car Pass)
The PIN code is supplied, but programming with a suitable diagnostic tool is still required. After installing the ECU, it must be reset using the supplied PIN code and then programmed to the vehicle’s immobilizer system.
b) VIRGIN ECU
The data from the previous vehicle is removed and the ECU is restored to a clean, factory-like state. After installation, it must be programmed to the vehicle using a compatible specialist diagnostic tool. Unless another preparation method is specified in the product description, this is the standard unlocking option for most of our ECUs.
c) Plug & Play – IMMO OFF
The immobilizer function is disabled in the ECU. After installation, the engine can start without additional immobilizer programming. Please note that the vehicle will no longer have an active immobilizer function, and an immobilizer warning light or fault code may remain, depending on the vehicle model.
d) Plug & Play – Automatic Programming
After installation, the ECU automatically learns and saves the required vehicle data. No additional programming is normally required.
e) Plug & Play – 1:1 Clone
The data from your original ECU is copied to another fully functional ECU. The cloned unit is then ready for installation without additional programming.
You must send us your original ECU so that we can transfer its data to the replacement unit.
The original ECU must have working communication with the vehicle, a diagnostic tool or our programming equipment. If the required data cannot be read, a complete 1:1 clone may not be possible.
3. Complete Plug & Play Set
A complete matched set containing the ECU, immobilizer components and all other parts required to start the vehicle without additional programming. All components supplied in the set must be installed in the vehicle.
Important:
Dispatch time depends on the selected option. If an unlocked or specially prepared version is ordered, the preparation service usually requires an additional 1–2 business days.

Does ECU 96801800 fit the Chevrolet Matiz with the 0.8 engine?
Yes, if the number on your ECU label is 96801800. This is a used, fully working engine control unit for the Chevrolet Matiz with the 0.8 engine. You choose the locked or unlocked version when ordering.
Engine control unit Chevrolet Matiz 0.8 96801800 5WY5407A
The engine control unit with number 96801800 is designed for the Chevrolet Matiz with the 0.8 engine. It controls engine operation and works together with the immobiliser. The part is used and fully working, and you confirm the fit with the number on the label.
Numbers to compare
- 96801800 – original number (OEM)
- 5WY5407A – control unit manufacturer number
- D32 – marking on the label
- 1BOT9A – marking on the label
Compatibility is determined by the number on the label, not by the car model alone. The ending of a number or an additional marking often points to a different version of the unit, so compare all the numbers.
Signs that the ECU may be faulty
- jerking and rough running with no fault in the fuel system,
- the ECU does not respond to the diagnostic tool,
- the engine suddenly cuts out,
- fault codes pointing to an internal fault in the unit.
Before removing the ECU, make sure the problem is not with the immobiliser, the key or the power supply.
Choosing an option
First decide who will do the programming. If your workshop does it, a locked ECU is enough – it comes with the donor car's data and immobiliser, ready for you to unlock, program and match yourself. If you would rather receive a unit that is already prepared, order the unlocked option; we do this before dispatch, usually within 1–2 working days.
Not every method (PIN / CAR PASS, Virgin, IMMO OFF, auto programming, cloning) can be used on every ECU. It depends on the part number, software and type of immobiliser, so ask before you buy. All options are described here: ECU preparation options.
Questions and answers
| Can I choose the ECU by car model alone? |
|---|
| We do not recommend it. The same model could have different units depending on the engine and year, so the number on the label decides. If in doubt, send us a photo of the label. |
| Does the 96801800 need coding? |
| The locked version does. The unlocked version is prepared before dispatch, usually within 1–2 working days. |
| Does this ECU come with a warranty? |
| Yes. It is a used, fully working unit in good condition. You will find the warranty period in the product specification table. |
