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 return pump motor runs only when ABS is active. The rest of the time it puts no load on the electrical system, but together with the valves it is one of the parts most exposed to wear.
Matching
Compare number 44540-52171 in full with the number on your pump. Different versions were fitted to the same models, so the number decides the fit, not the model alone. Modules differ, among other things, in the layout of the brake line ports and the connector. Always compare the numbers and the appearance of your pump with the unit in the listing.
Symptoms of a faulty ABS pump
- an ABS fault appears after replacing the battery,
- the voltage at the module is unstable,
- the brake and ABS warning lights come on together,
- the brakes work, but without ABS assistance.
If the brake system has been opened, it must be bled after fitting, often using a diagnostic tool that controls the ABS valves.
