Comprehensive Fault Code Analysis & Solutions

Based on full-system fault code reading, combined with real-time data streams and freeze frames, pinpoint the causes of intermittent or persistent faults. Using a high-sampling-rate oscilloscope, pressure sensor array, temperature simulator, and CAN bus analyzer, along with original factory-grade circuit diagrams and a repair database, accurately diagnose deep-seated problems such as sensor drift, actuator jamming, and excessive line contact resistance.
