LICAEVEY 1K0907379AC – ABS/ASR control module with hydraulic unit

LICAEVEY 1K0907379AC – ABS and ASR control module with hydraulic unit

This is a brake system control unit marked with OE number 1K0907379AC, found in parts catalogs for Volkswagen Group cars. The module combines electronics with a hydraulic unit that regulates fluid pressure in the individual brake circuits. This allows the ABS anti-lock system and the ASR traction control system to react to a loss of wheel grip.

How the ABS and ASR controller works

The controller receives signals from the wheel speed sensors and uses them to detect the moment a wheel starts to lock up or spin. At that moment the module briefly reduces or increases pressure in the brake of the given wheel, which helps maintain the car's stability and handling on wet and slippery surfaces.

Use

• replacing a damaged brake system controller,
• repairing faults indicated by the ABS warning light on the dashboard,
• restoring system function after a failure of the hydraulic unit electronics.

Specifications

Before buying, check that the part number matches the code in your car, preferably by VIN. After replacing the controller, the brake system must be bled and the module configured and coded, which should be entrusted to a qualified workshop, because driving safety depends on this installation.
