TL;DR
When an EV won’t start, the issue is often the 12V auxiliary battery, not the high-voltage battery pack. The low-voltage system powers computers, relays, and safety systems that allow the vehicle to boot up. Understanding EV battery failure symptoms, DC-DC converter function, and diagnostic steps is essential for modern technicians.

DoIP diagnostics (Diagnostics over IP) allows technicians to communicate with vehicle modules using automotive Ethernet instead of traditional CAN systems. Built around ISO 13400 standards, diagnostics over IP supports faster programming, advanced ADAS calibration, and software-driven vehicle systems. Understanding this technology is b...
TL;DRAs SAE J3400 (formerly NACS) gains industry adoption alongside CCS, EV charging problems are becoming more complex. Mechanics must understand charging standards, adapters, and safe diagnostic procedures to identify root causes accurately and avoid guesswork.
Electric vehicles are not just changing powertrains. They are reshapin...

UDS is essentially the “language” that many scan tools use to communicate with vehicle computers (ECUs). It’s defined by ISO 14229 and lets a diagnostic tester (scan tool) control diagnostic functions in an ECU.
A scan tool sends diagnostic services (commands), the ECU answers back, and that’s how y...

EV mechanic safety comes down to three habits you repeat every single time:
Assume the high-voltage system is live until you’ve shut it down, isolated it, and verified the absence of voltage. Use PPE that matches the risk (especially insulated glove...
