A Tesla high-voltage warning can be worrying, but it does not always mean the complete battery pack needs replacing. AutoNet VIP provides specialist battery and high-voltage diagnostics for Model 3, Model Y, Model S and Model X, helping identify the actual cause before major repair decisions are made.
The high-voltage battery is one part of a wider system. A fault can also involve the BMS, contactors, safety devices, cooling components, power conversion or the low-voltage supply. Our diagnostic process is designed to establish where the problem is before recommending repair or replacement.
For suitable Model S and Model X faults, module-level battery repair may be an option. Every vehicle must be diagnosed first so we can determine whether module replacement is appropriate.
High-voltage repairs depend on the model, fault, battery condition and availability of suitable components. We will diagnose the vehicle first and explain the options before work proceeds.
