OBD II Fault Code


    OBD-II Code Wiring issue is defined as a Hybrid Battery Pack Cooling Fan Sense Circuit Intermittent/Erratic

    The Hybrid Battery Pack Cooling Fan draws air through the hybrid battery pack to help control the temperature of the high voltage battery. The fan is controlled by the Starter/Generator Control Module. If this module detects the Cooling Fan is not operating as requested, code P0BCB will be stored.

    Common Problems That Trigger the P0BCB Code

    • High voltage battery pack cooling fan failure
    • Starter/generator control module failure
    • Wiring issue
