HV Battery: End of Service Test Failed. Following any HV battery repairs on the I01, it is necessary to validate the repair using the End of Service (EOS) Tester. In the following scenarios, the EOS test is not completed successfully, despite the repair being completed properly. In these cases, the HV battery cannot be reactivated. 1. Faults stored in the SME: Following an HV battery repair, the EOS test fails due to faults stored in the battery management electronics (SME) from the previous failure, before the repair took place. In this scenario, the test will fail immediately after starting, at the point where the SME fault memory is read. 2. Activation code: Upon successfully completing the EOS test, an 11-digit code is displayed, yet ISTA/D requires a 12-digit code to reactivate the battery. The EOS tester was distributed to all BMW centers via the Automatic Tool Shipment program. Details can be found in SI B04 09 14. CAUSE Software error in the EOS tester.
