Dead on Arrival: Hybrid & Electric Vehicle Diagnostic Strategies
When a hybrid or EV won’t go Ready, the diagnostic challenge gets serious. Learn how to safely diagnose high-voltage faults, interlock issues, isolation failures, and no-Ready conditions using practical strategies drawn from real-world vehicles and multiple manufacturers.
Description
When a hybrid or electric vehicle won’t “ready-on,” it’s more than an inconvenience. High voltage faults do not result in a fail-safe / limp-home strategy, so these vehicles arrive on the flatbed. In this course, we break down the real-world causes behind these failures. Participants will learn how to identify why a vehicle cannot enter ready mode, understand the underlying high-voltage system conditions that trigger these events, and apply practical diagnostic strategies to get vehicles back in service safely and efficiently.
What we'll cover:
- Real-world examples from multiple manufacturers / platforms
- High voltage system diagnostic process
- Working safely on EVs
- Interlock system faults
- Loss of Isolation - now what?
- Can I test these systems with my multimeter or will I need new equipment?
