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.

Mercedes ABS pump: numbers A2224314512 and 0265243576
The hydraulic block and control unit of this ABS pump form a single module that works with the wheel speed sensors in Mercedes cars. You will find number A2224314512 on the label, and the full set of numbers is given in the description below. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Numbers to compare
The numbers as written on the labels and as a single string, the way catalogues list them:
- A 222 431 45 12 (catalogue format: A2224314512), Mercedes number stamped on the hydraulic block,
- 0 265 243 576 (catalogue format: 0265243576), hydraulic block manufacturer's number,
- 0 265 956 109 (catalogue format: 0265956109), control unit number.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
What can point to an ABS pump failure
- 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,
- brake fluid leaks from the hydraulic block, which requires immediate action.
First check the wheel sensors, their wiring and the supply voltage. Only a fault code pointing to the module justifies replacing the pump. After fitting, clear the fault codes and, if necessary, bleed the brake system.
