Help!!! Codes P08A3 and P0A37 Prius 2005

Sure, go to the rear hatch and open it. Remove the carpet, trunk flooring and the tire tools in the black plastic case. You should see the spare tire.
Now, there should be a long or wide aluminum box, that's the traction battery. On the driver's side, you should see an orange plastic device. Its not easily removed but it can be done. There are two distinct movement. You flip it up is the first latch. Then you have to pull it up. It should now be removed from the vehicle. I also believe its in the owners manual.

Once that is removed, your vehicle is disabled until the safety plug is put back in place.

I would even remove the ground or nehative cable from the small 12 volt battery which is located in the right side of the trunk.

Good luck, I hope this does this. If not, you can go to the Toyota dealer for help. The codes could be assessed by them. Then you could also get the air out of the system.

I have not heard of any reason to unplug the orange interlock switch, just to reset the car. When watching a Dorman video that shows the procedure to unplug that orange interlock switch, they recommend wearing protective gloves in doing so, for your own safety. A simple unplugging of the 12v negative should do the trick to reset the ECUs.

 

Am I the only one that finds this comical for all the wrong reasons? Its like those low budget horror flicks where the people run to the killer, instead of away.

I feel bad for OP, b/c he financed a purchase from the sleazy used car lot, and took their word that the warning lights were "decorative" dash lights. (being sarcastic)

Is OP even aware that the HV Battery will go out in the near future? What does he plan to do then? Can he afford a NEW HV Battery from a Toyota delaer who sells on-line? $1900-$2200, and would require will call pickup. A "rebuilt," costs slightly less, but is a terrible long term purchase, IMO. A module swap seems to be an exercise in futility.

 

I agree, why did the used car lot even sell this vehicle without fixing it first?

Isn't it a law in most states you can not sell a vehicle with the Check Engine light illuminated? The car would possibly not pass an emissions test. Now the owner is thinking Prius or Toyota sucks when the reality is the used car dealer should repair it or get them a different vehicle.

Now that would turn a negative situation into a positive event. Could they hire a lawyer for this problem? I also wonder if they signed something at purchase time that said " Vehicle sold as is, no WarrantY implied or given". If that big red triangle of death was on, I would not have even looked any further, unless I need a parts car, in my opinion.
