Se 5201

This document provides diagnostic information for a Volvo vehicle with serial numbers between 11001-99999. It describes a fault code detected by the vehicle control unit related to the front brake pressure being too high or too low. Specifically, fault mode 3 indicates the voltage is above 4.75V, possibly due to issues with ground cables or sensors. Fault mode 4 means the voltage is below 0.25V, possibly because of open circuits, shorts to ground, low feed voltage, or defective sensors. The document instructs technicians to check SE5201/SE5202 for descriptions and measuring procedures.
