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.

Is ABS pump 9666999580 the right part for your Citroën?
The hydraulic block and control unit of this ABS pump form a single module that works with the wheel speed sensors in Citroën C3 Picasso 1.6 HDI cars. You will find number 9666999580 on the label, and the full set of numbers is given in the description below. According to the listing, the pump comes from the Citroën C3 Picasso 1.6 HDI model.
Where to find the numbers on an ABS pump
You will find the numbers on the labels, while catalogues list them as a single string:
- 9666999580, original Citroën number,
- 10.0206-0414.4 (catalogue format: 10020604144), hydraulic block manufacturer's number,
- 10.0960-3924.3 (catalogue format: 10096039243), control unit number.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
What ABS problems can point to
- the ABS warning light comes on after the engine is started and stays on,
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- 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.
