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.

What does the number 036906034JE on a Fabia ECU mean?
036906034JE is the VW/Skoda part number: the core 036 906 034 indicates an engine control unit, and the letters JE its version. This used, fully working unit is a Magneti Marelli IAW 4TV.JE for the petrol Fabia.
Engine Control Unit Skoda Fabia Magneti Marelli IAW 4TV.JE 036906034JE
On this ECU the only number to compare is the VW number 036906034JE, so it is worth knowing how to read it. Group 906 denotes an engine control unit, and the letters JE a specific software and hardware version. This Magneti Marelli IAW 4TV.JE unit came from a petrol-engined Skoda Fabia; we do not give the engine size.
Markings to check
- 036906034JE – VW/Skoda part number, version JE
- IAW 4TV.JE – Magneti Marelli ECU type
The JE suffix appears in both the VW number and the IAW type. If your unit shows a different combination of letters, it is a different version – please contact us before you buy.
Typical symptoms
- the starter turns, but the engine will not fire,
- unstable revs and stalling when you lift off the accelerator,
- the injectors or coil receive no signal,
- the engine warning light is on and the diagnostic tool cannot see the unit.
Before replacing it, check the power supply, earths and connector – a damaged wire produces identical symptoms.
Available versions
When buying this ECU, you choose between two versions. The locked one retains the previous car's data and immobiliser – the garage carries out the unlocking, programming and adaptation. With the unlocked one, we do all the preparation 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 unit – it depends on the part number, software and immobiliser. Please ask before you buy. More: ECU options.
