Code P1EB4 Description

When the Battery Energy Control Module is flash programmed, the Hybrid/EV Battery Interface Control Module operating software and calibrations are provided to the Battery Energy Control Module. The Hybrid/EV Battery Interface Control Module software and calibrations are then loaded to each of the Hybrid/EV Battery Interface Control Modules from the Battery Energy Control Module. This operation is automatic and requires no operator action. At this point, if any of the Hybrid/EV Battery Interface Control Modules are not programmed correctly, the appropriate DTC is set.
This fault is internal to the Hybrid/EV Battery Interface Control Modules and no external circuits are involved.
