Need Checklist to get the 'Ready Light' on

I don't think you have to have a ready light to scan the car accessory mode will be fine I think that's two pushes of the button no break in a generation 3 your display is all lit up now All the amber lights are on a whole Christmas tree of nonsense plug in your scanner follow the prompts If you have any regular p codes and normal codes a lot of modern scanners will read a lot more than you think. If you don't have anything maybe get somebody that has autel or TIS on tap. And see what they see and go from there You should have some kind of information coming from all the computers in the car lost communication so on and so forth whatever they'll be I don't believe you need ready to read code matter of fact I know that's the case just like generally you can't have the engine running when you clear the codes in a Prius the car can be on but the codes won't clear if the engine is hammering up and down firing running as soon as it dies I hit the button to clear the codes and because the engine's not running they'll clear

 

I’m not familiar with the Owners Manual for your car but in the manual for my ‘22 under section 7.2 it has several options that might help. Look under “The Hybrid System Will Not Start”.

 

You've got to have your foot on the brake pedal, and there's a switch there that confirms brake pedal is depressed. Maybe it's out of adjustment or defective?

 

Accessory mode is one push of the button, no brake. It only lets you use a few things like the infotainment system.

Two pushes without the brake is IG ON mode. The dash lights all up and you can scan things.

 

You got to have the dash lit up completely without the ready light whatever makes that happen in your particular model will yield scan. I got a Gen 3 right now no matter what mode it's in TIS or tech will not connect to the car I don't care what you do but a cheap piece of crap hooks up connects and scans without issue It's just the cheap scanner can't read the complete car kind of a big problem.
