Complaint Combustion engine does not start, MIL (Malfunction Indication Light) may light up in instrument cluster, only electric driving possible. Fault code P0E2F00 logged in control unit BMS N82/10. Cause Auxiliary consumer fuse in the HV battery has an open circuit, caused by a short circuit in the auxiliary consumer line. Remedy Requirement: Before carrying out test work, it must be ensured that the person performing the work has successfully completed the required qualification for work on the high-voltage system. Qualification according to WIS is required to replace the auxiliary consumer fuse including eLearning T3057D-US.TTB. Note: If the fault "P0E2F00 The electrical fuse B for the high voltage has a malfunction" is stored in the N82/10 BMS control unit, the HV protocol must also…

Complaint Combustion engine could no longer be started, only electric driving possible Cause High-voltage belt-driven starter-alternator defective Remedy Requirement: Before carrying out test work, it must be ensured that the person performing the work has successfully completed the required qualification for work on the high-voltage system. Note: In order to check whether the high-voltage belt-driven starter-alternator is defective, please carry out the test below. If the fault "P0E2F00 The electrical fuse B for the high voltage has a malfunction" is stored in the N82/10 BMS control unit, the HV protocol must be checked to see whether the fuse for the auxiliary consumers is defective. In this case, the high-voltage battery must be replaced after the short circuit has been eliminated.…
