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 hydraulic unit contains solenoid valves and a return pump motor. When the control module detects a wheel locking, the valves briefly reduce the pressure in its circuit and the pump returns the fluid, so the driver keeps control of the car's path.
Matching
Compare number 90 581 418 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 and year alone. The fit is decided first of all by the part number, and only then by the model and year, because different modules were used within one model.
Symptoms of a faulty ABS pump
- the ABS warning light comes on once the car has warmed up,
- the brake pedal vibrates for no reason,
- no communication with the module over the CAN bus,
- the system switches to emergency mode.
Check the level and condition of the brake fluid; old or contaminated fluid accelerates wear of the valves in the hydraulic unit.
