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:

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.

Mazda 323F 1.5 engine control unit Z5B518881A: how to match it by part numbers?
This is a used original engine control unit which, according to the listing data, is for the Mazda 323F with a 1.5 engine. The label shows the Mitsubishi Electric Corp. mark and the markings Z5B56J, Z5B518881A and E2T86886M. The model and engine capacity are not enough to confirm compatibility, so compare the full set of numbers from the label.
Numbers from the label to compare
The housing has a single label, which is partly torn, so also rely on the numbers given in the listing. The label shows:
- marking Z5B56J,
- Mazda part number Z5B518881A, written on the label with spaces (Z5B5 18 881A),
- manufacturer's marking E2T86886M.
The housing has metal mounting brackets, but compatibility is determined by the numbers, not by appearance.
Control unit variant
This listing is for a control unit in the following variant(s): Locked / Unlocked. We describe the differences between the variants (locked, unlocked, Virgin, IMMO OFF, Plug and Play, clone, full set) on the ECU preparation options page. Before buying, send us the numbers from the label and we will confirm which variant is available for that number.
When an engine control unit needs replacing
- the engine does not start even though the starter motor and fuel are fine,
- the engine warning light is on and does not go out,
- the diagnostic tester cannot connect to the control unit,
- the engine runs unevenly or stalls for no obvious reason.
Before buying a control unit, check the fuses, power supply, earth connections and connector, because similar symptoms are often caused by an ordinary wiring fault.
