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.

Looking for the 33920-80GE ECU for your Suzuki?

Engine control unit Suzuki Denso 33920-80GE 112200-3192
This used Denso 33920-80GE engine computer for Suzuki vehicles processes sensor signals and calculates the engine’s operating parameters. We do not state a model or engine that the label does not confirm; the part numbers decide the fit. The label shows the following markings: OL, EU MT 2WD, 33920-80GE, 080GA, 112200-3192. The marking “EU MT 2WD” on the label indicates the version with manual transmission (MT) and two-wheel drive (2WD) for the European market.
ECU markings
- 33920-80GE – Suzuki part number
- 112200-3192 – Denso number
- 080GA – additional marking
Compare them with the sticker on the ECU in your car. The number decides the fit, not the model alone – Suzuki used different ECU versions.
Symptoms of a faulty engine ECU
- the starter cranks but the engine does not fire,
- the diagnostic tool cannot connect to the ECU,
- an engine warning light and fault codes that remain after replacing sensors,
- signs of moisture or corrosion on the connectors or circuit board.
Before buying, check the ECU earths and wiring, as a damaged loom produces similar symptoms.
Locked or unlocked version?
A locked ECU holds the data and immobiliser of the previous car – it is chosen by garages that will program it themselves. The unlocked version is prepared by us before dispatch.
The available unlocking methods depend on the ECU number and the immobiliser system, so before buying ask what we can prepare for the 33920-80GE unit.
All variants are described on our Locked & Unlocked ECUs page.
