Tesla Model S Faulty Battery Module

Tesla Model S Diagnostic Report

In this case the vehicle presented with the Tesla Model S won’t start condition and a warning message on the dashboard (“Engine may not re-start after shut down”). A full diagnostic scan was executed, identifying multiple system faults suggestive of a high-voltage battery pack or BMS failure. The work proceeded to isolate the root cause via live data, fault-code analysis, insulation tests and subsystem isolation.

Tesla Model S Repairs

The repair process included removal of the relevant high-voltage systems (battery pack/BMS), module replacement or repair, system resets and full functional verification. The vehicle was retested to confirm it now enters drive/ready mode and all warnings are cleared.

Resolution

After the specialist intervention, the Tesla Model S won’t start fault was resolved. The vehicle enters ready mode, drives normally, fault messages no longer appear, and the car was returned to the customer in full operational condition.
