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
During normal driving the system is passive and the brakes work conventionally. Only under hard braking does the pump start to pulse, and you can feel vibrations in the brake pedal.
Matching
Compare number 4N51-2C405-AD 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. Module numbers are written with spaces or as one string. We give both forms to make the part easier to find.
Symptoms of a faulty ABS pump
- ABS does not react to wheel slip,
- ESP or ASR does not switch on,
- power supply faults in the diagnostic memory,
- signs of corrosion are visible on the connector.
Before you buy a pump, check the fuse, power supply, earth and wheel speed sensors - a damaged wiring loom or sensor can cause similar symptoms.
