I'm troubleshooting a Volvo L120F that keeps showing a brake system failure warning even though the brake pressures seem to be within spec. I've checked accumulator pressure, brake applications, and pump performance, and everything looks normal so far. The warning clears temporarily when pressure rises, but returns during normal operation. Has anyone dealt with this before or found a common cause, such as a pressure sensor, wiring issue, or control valve problem?
