Q: What does code P0B36 mean?

High Voltage Service Disconnect Circuit High. P0B36 indicates that the high-voltage service disconnect circuit has been detected as having a voltage higher than expected by the battery energy control module. The computer monitors the service disconnect loop and sets this code when the signal voltage exceeds the calibrated threshold, typically indicating an open circuit or a fault in the disconnect switch itself.
