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.

Will the 33920-61GB0 ECU fit your Suzuki?

The Denso module 33920-61GB0 controls the engine – it reads sensor data and uses it to regulate the fuel system. It is a part for Suzuki vehicles. 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: 6Q, 1.6 94/12 IMM, 33920-61GB0, 61GB, 112000-4351.
Numbers to check
- 33920-61GB0 – Suzuki part number
- 112000-4351 – Denso number
- 61GB – additional marking
You will find the numbers on the casing of your current ECU. A similar-looking unit will not necessarily fit – the full number is what counts.
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?
In the locked version the ECU still stores the data of the car it came from and needs programming at a garage. The unlocked version is prepared by us before dispatch.
Not every unlocking method is possible for every ECU – it depends on the number, the software and the car’s immobiliser. Before ordering the unlocked version, ask us about the options for the 33920-61GB0 ECU.
All variants are described on our Locked & Unlocked ECUs page.
