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.

Numbers to compare
The numbers as written on the labels and as a single string, the way catalogues list them:
- A 000 446 68 89 (catalogue format: A0004466889), Mercedes number stamped on the hydraulic block,
- 0 265 225 224 (catalogue format: 0265225224), hydraulic block manufacturer's number,
- 0 265 950 098 (catalogue format: 0265950098), control unit number.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
Symptoms of a faulty ABS pump or control unit
- the ABS warning light comes on after the engine is started and stays on,
- the ABS stops working, although basic braking usually remains functional,
- the brake pedal pulses or feels uneven for no obvious reason,
- valve or pump motor faults are stored in the control unit memory.
Before buying a module, read the fault codes with a diagnostic tester. A faulty wheel speed sensor or its wiring can cause the same symptoms, and in that case replacing the pump will not help. After replacement the fault codes usually need to be cleared, and if the brake lines have been disconnected, the system must be bled.
Questions and answers
| Are the make and model of the car enough to choose the part? |
|---|
| No. A single model comes with different versions of the module, depending on the engine, year of manufacture and drivetrain. The most reliable reference is the number on the original pump. |
| Are the pump and the control unit sold separately? |
| In this listing they are a single module: a hydraulic block with the pump and valves, with the control unit attached to it. |
| Do the brakes need bleeding after replacing the module? |
| If the brake lines are disconnected during fitting, the system must be bled. The fault codes in the control unit usually need to be cleared as well. |
| What condition is this ABS module in? |
| It is an original recycled part in good condition, checked by us. Warranty details are in the product features table. |
