Wrench light appears on dashboard-Hybrid Battery Cooling System Service needed- how much is this any

make sure the intake grille(s) are clear.

 

I know this is an old post, but did you ever get your issue resolved? If so, how?

 

Original Poster never came back.

I would start by cleaning the hybrid battery fan, it's the most likely cause.

How many miles on it, and do have shedding pets in the car?

 

It's really interesting question. Hope, somebody will share their experiance and knowlege. Simetimes i saw wrench light on my dashboard, but then it go missing. It's strange.

 

I'd like to try to clean my battery fan and filter. I'll have to start by cleaning off my back seat. What is the name of the tool used in the video to remove the clips? Where can I get one? I've been getting errors about the battery cooling system on long trips during the last month but the message goes away the next day after the car cools down.

 

You have a Prius v? If it’s similar to 3rd Gen hatchback Prius, it’s not necessary to remove the rear seat cushion:

also see video #21 here, the @NutzAboutBolts video. They remove the seat cushion, but again, not necessary:

One of the many reasons a v is better than a hatchback is it only takes one easy 10mm screw to access the hv battery fan. Mostly due to the sliding and reclining rear seats.
