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 9858993780 the right part for your Citroën?
ABS pump 9858993780 for Citroën Peugeot is a used original module that regulates brake pressure when a wheel starts to lock up. It is matched by the numbers on its labels, not by the car model alone. According to the listing, the pump comes from the Citroën Peugeot model.
Part number 9858993780 and related numbers
The numbers as written on the labels and as a single string, the way catalogues list them:
- 9858993780, original Citroën number,
- 10.0917-3981.3 (catalogue format: 10091739813), 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 warning light comes on together with the stability control warning light,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
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.
Questions and answers
| Are the pump and the control unit sold separately? |
|---|
| In this listing they are a single module: a hydraulic block with the pump and valves, with the control unit attached to it. |
| Does a lit ABS warning light always mean a faulty pump? |
| No. Read the fault codes first, because the cause may be a wheel sensor, its wiring or too low a supply voltage. |
| Who makes this module? |
| The module is made by ATE. The manufacturer's name does not change the numbers you should use to match the part. |
| Is this a new part? |
| No. We sell used original modules, each one inspected before sale. You will find the warranty period in the product features table. |
