Repxpert ABS Sensor Card An invaluable free* tool for LKQ Euro Car Parts customers The vast majority of wheel bearings currently fitted as Original Equipment (OE) are classed as “Active Sensor Bearings”, which contain a special magnetic sensor ring integrated into the seal.

This sensor ring provides valuable speed data to the ECU which is used to manage the wide range of safety critical electronic assistance devices fitted to a modern vehicles, such as ABS, traction control, and cruise control for example. However, it is not really possible to visually check if the bearing you have been supplied is fitted with an encoder within the seal. As we’ve already said, the sensor ring is magnetic, and it is common place for mechanics to check if the seal contains a sensor ring by holding a screwdriver against it. However – a word of warning!… Many screwdrivers are magnetic and can cause damage to the sensor if it comes into contact.

For a more accurate way of testing a bearing seal for a sensor, or to check the sensor for damage when diagnosing wheel bearing issues, place the FAG encoder reader card across the face of the seal. You will quickly see if it contains the magnetic sensor ring, and more importantly, if there are any signs of damage to the sensor ring.

Note: Damage can also occur in new bearings during transportation or due to rough handling.
