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
The number 12773673 also appears in another listing. Compare all the numbers with the label on your pump - we do not assume that listings are interchangeable. After replacement the module may need coding or adaptation to the car. Check this for your model before ordering the part.
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.
Check the level and condition of the brake fluid; old or contaminated fluid accelerates wear of the valves in the hydraulic unit.
