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.

How to check whether ABS pump A0054315012 fits your Mercedes
Used ABS pump with control unit, number A0054315012, inspected before sale. Matched by the numbers on the block and sticker.
Mercedes ABS pump: numbers A0054315012 and 0265250082
This module is made by Bosch. ABS pump A0054315012 is sold together with its control unit, just as it is fitted to Mercedes cars. 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 005 431 50 12 (catalogue format: A0054315012), Mercedes number stamped on the hydraulic block,
- 0 265 250 082 (catalogue format: 0265250082), hydraulic block manufacturer's number,
- 0 265 960 023 (catalogue format: 0265960023), control unit number.
Check the numbers on your pump and compare them with those above. If any of them differs, contact us before ordering.
What can point to an ABS pump failure
- the brake pedal pulses or feels uneven for no obvious reason,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS switches itself off shortly after the engine is started,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
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.
