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 A2214310848 and 10021207424
If the ABS warning light is on in your Mercedes, one possible cause is the hydraulic module or its control unit. ABS pump A2214310848 is a used original part, inspected before sale. 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 and markings on the ABS pump
You will find the numbers on the labels, while catalogues list them as a single string:
- A 221 431 08 48 (catalogue format: A2214310848), Mercedes number stamped on the hydraulic block,
- 10.0212-0742.4 (catalogue format: 10021207424), hydraulic block manufacturer's number,
- A 221 901 48 00 (catalogue format: A2219014800), Mercedes control unit number.
Check the numbers on your pump and compare them with those above. If any of them differs, contact us before ordering.
When an ABS module needs replacing
- the ABS warning light comes on after the engine is started and stays on,
- valve or pump motor faults are stored in the control unit memory,
- the ABS activates for no reason during normal braking,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
ABS faults should not be ignored, because without anti-lock protection the car brakes less well on wet or slippery roads. Diagnosis and fitting are best left to a garage with a suitable scanner.
