Overview

EV Diagnostics & Programming in Massachusetts 🇺🇸

Independent shops won't open a high-voltage pack; dealers quote weeks of wait and full-assembly swaps. We diagnose at the component level — drive units, inverters, BMS, charging — and provision replacement modules so your EV runs again.

Drive unit & inverter teardown diagnostics
BMS analysis, resets and calibration
Charging faults — AC onboard & DC fast charge
Pre-purchase battery health & SOH assessment
Module provisioning after replacement
Firmware / 12V no-start conditions

Available across Boston, Worcester, Springfield, Cambridge, Lowell, Brockton, Quincy, Lynn, New Bedford, Fall River, Newton and Lawrence — plus the rest of Massachusetts by mobile, in-house or mail-in service.

Questions

❓ FAQ

Which EVs do you work on?

Primarily Tesla, with support for other EV platforms. Send your model and we'll confirm coverage before you commit.

Can you check battery health before I buy a used EV?

Yes — a pre-purchase assessment pulls live pack voltage, cell balance, isolation and an estimated state-of-health so you know what you're buying.

Do you replace high-voltage batteries?

We diagnose pack and BMS faults and handle module programming; full pack replacement is quoted case by case.

Is high-voltage work safe at an independent shop?

With proper training, PPE and procedures, yes. We follow OEM isolation and lockout steps on every HV job.
