Question
What is the diagnostic importance of EV battery management system (BMS) communication with the instrument cluster?
Answer
It ensures accurate battery status display for the driver.
Explain
BMS-cluster communication faults hide battery state information. CHEPQ diagnostic tools monitor CAN messages between BMS and cluster, detect missing or corrupted data, and verify message ID/format. This ensures the driver receives accurate SOC, range, and warning information.
