4099 SPN Fault Code

Name:

XBR urgency

Description:

The idea of the urgency value is to adjust the endurance brake integration behavior in the EBS system according to the traffic situation.On low urgency values (0%, e.g. downhill cruise control or preceding vehicle far ahead) the brake system shall primarily use endurance brakes to reduce lining wear. On high urgency values (100%, e.g. vehicle close up or a vehicle cuts into the traffic line just before host vehicle) the brake system is expected to gain the demanded deceleration (acceleration) as fast as possible. Values: 0% – Situation not critical; low retarder dynamics are tolerated. Activation of the foundation brakes after a time if retarder performance is insufficient y % – Faster activation of foundation brakes to compensate retarder performance, linear interpolation between 0 and 100% 100% – Low retarder dynamics shall be fully compensated by the foundation brakes Notes: – This parameter has only an effect if XBR EBI switch is set to « 10b: endurance brake integration allowed »

4099 spn fault code name is XBR urgency. If you don't take the time to look into 4099 spn fault when it arises, it can add up quickly. One small issue like 4099 can cause a larger component to become damaged without taking the time to investigate.
