How to keep power on without engine running

JayD · 06-07-2024, 10:10 AM

Stupid question but I want to keep assessory power on without the engine running while I program my CANDO + I drive controller. It can take over 5 min to download the software updates. When I tried, the car accessories shut down before it was done. What am I missing here.
Thanks.

It’ll put the car in diagnostics mode, which is what you’re looking for.

...and rub your belly and scratch the top of your head at the same time.

Thanks for the info. Especially the rub your belly part. I’m real good at that! 😁
