Résumé du constructeur

Texte original en anglais

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. (See attachment) The defective high-voltage belt-driven starter-alternator must always be sent back via the existing return delivery process for analysis. Check: Please disconnect the high-voltage plug at the high-voltage belt-driven starter-alternator and connect test adapter 000 589 94 63 00. Measure resistance HV+ to HV-. If the final measurement result is between 0–1 ohm, the high-voltage belt-driven starter-alternator with the short circuit must be replaced. If either one of or both the fault codes P0C0B16 and P0C0B17 are saved in the high-voltage belt-driven starter-alternator control unit G2/3, please replace the high-voltage belt-driven starter-alternator, since no short circuit can be measured here and this therefore concerns a hardware defect. Please check the serial number on the silver adhesive label below the SW number on the front of the high-voltage belt-driven starter-alternator. Example: 2314300044 (the first 10 digits, see attachment) Important note: If the number is greater than 2329100027, a TIPS case must be created. In this instance, please attach the following documents to the TIPS case: • Quick test • High-voltage event log • Picture of the silver adhesive label on the front of the high-voltage belt-driven starter-alternator (serial number) • Attach the measurement results with pictures
