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 and markings on the ABS pump
The numbers from the listing, as written on the labels and as a single string:
- A 004 431 48 12 (catalogue format: A0044314812), Mercedes number stamped on the hydraulic block,
- 0 265 202 493 (catalogue format: 0265202493), hydraulic block manufacturer's number.
Check the numbers on your pump and compare them with those above. If any of them differs, contact us before ordering.
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 pump motor switches on at unusual moments or runs louder than usual,
- 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.
Questions and answers
