Q: What are the symptoms of a failing wiring harness on a Komatsu PC200-6 or PC270-6?
A: Common symptoms include intermittent electrical faults, multiple warning lights illuminated on the monitor panel, unresponsive controls, erratic gauge or sensor readings, CAN bus communication errors, specific hydraulic or engine functions not responding, unexpected machine shutdowns, or recurring diagnostic trouble codes. On PC200-6 and PC270-6 models, harness degradation is often accelerated by heat exposure in the engine compartment, vibration, and moisture ingress at connector joints.
