Hybrid And Electric Vehicle Precautions: 2019 Chevrolet Volt

There are many precautions and instructions to follow while repairing hybrid and electric vehicles. To help you find this information, RTS has an OEM Hybrid And Electric Vehicle Disable Search page. Here you will find step-by-step instructions on how to find the disable procedure in the service manual. You will also find precautions for welding, refinishing, and if a scan tool and DVOM are required for disabling. Let’s take a look at the 2019 Chevrolet Volt.

The full OEM Hybrid And Electric Vehicle Disable Search page for the 2019 Chevrolet Volt can be viewed on the I-CAR website. This will give you a good understanding on precautions needed while repairing the vehicle. I-CAR does not have permission to show procedures. However, Chevrolet has a paid subscription website with hybrid disabling procedures.

There are many things to keep in mind while repairing a high-voltage (HV) vehicle, as opposed to a vehicle with a 12 V battery system and a gasoline engine. This is why it is important to follow the procedure on the OEM service site.

Here is an example of information you will find in the disable procedure: per the 2019 Chevrolet Volt service manual, High Voltage Disabling: “Note: The High Voltage Disable procedure, regardless of the method, only de-energizes the high voltage circuits and components outside of the Hybrid/EV battery pack, dangerous voltage levels always exist within the Hybrid/EV battery pack.”

The service manual also states that a scan tool and a high-voltage DVOM is needed to disable the high-voltage battery system.

Always follow the OEM procedure for disabling a high-voltage system in order to ensure a complete, safe, and quality repair.
