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 an ABS pump with control module works
The module electronics store fault codes that can be read with a diagnostic tool. This makes it easier to determine whether the sensors, the wiring or the hydraulic unit itself is to blame.
Matching
For this model we offer several pumps with different numbers. The number on the label decides, not the model name alone. The same car model may have had several module versions, depending on drive, equipment and year. The numbers in the list help to tell these versions apart.
Symptoms of a faulty ABS pump
- the ABS warning light goes out and comes on by itself,
- the wheels lock under hard braking,
- the tester shows a control module or valve fault,
- traction control switches off.
Check the level and condition of the brake fluid; old or contaminated fluid accelerates wear of the valves in the hydraulic unit.
Questions and answers
| What does “used, working” mean? |
|---|
| We sell it as a used part, in working order and in good condition; this information is also given in the listing features. |
| Does the control module need coding after the pump is replaced? |
| It depends on the make, model and version. Before buying, check whether your car needs adaptation or coding after the replacement. |
| Do the brakes need bleeding after replacement? |
| Yes, once the brake system has been opened it must be bled. In many cars this is done with a diagnostic tool that activates the ABS valves. |
