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 identify ABS pump 9819474780 for your Citroën
This is a used original ABS pump with a control unit for Citroën cars: an aluminium hydraulic block with valves and a pump motor, with the electronics bolted to it. The main number is 9819474780, and the other numbers from the labels are listed 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 and markings on the ABS pump
You will find the numbers on the labels, while catalogues list them as a single string:
- 9819474780, original Citroën number,
- 10.0915-3992.3 (catalogue format: 10091539923), 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 ABS warning light comes on after the engine is started and stays on,
- the brake pedal pulses or feels uneven for no obvious reason,
- the pump motor switches on at unusual moments or runs louder than usual,
- the ABS warning light comes on together with the stability control warning light.
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.
