HV Battery and fan

At your year and mileage, it would be reasonable to assume the failure is the battery. On a newer car with far less miles, then we can think it might be the connector and not the battery

 

Though it's too much trouble for most people, I monitor the fan speed, as well as a lot more. Here is a picture of the IPad app I have running all the time. I also use Waze for navigation (IPad) and switch from app to app. It's strapped to my center console just aft of the shifter.

"C Fan O" the round dial at 36% is the battery fan.

 

I apologize to the OP for high jacking his thread, BUT I have a question for you.

What PID are you using for the Hybrid Battery Pack Remaining Life? I have Engine Link and monitor all of the PID's in your display except this one.

 

Locate the cracks in the hatch channels, clean with rubbing alcohol or the like, and fill with clear windshield silicone or whatever you feel will do a decent job of waterproofing. See posts 49,50,54 and 59 of this thread for pics of the suspect areas/cracks:

I agree with JC, your HV battery died of old age after a pretty stellar (typical) run. Perhaps the fan contributed to a somewhat "premature" death but at that age and mileage, it would be tough to prove it. More excellent detective work locating the corroded connector. This is beginning to surface as an area to keep an eye on for aging gen 2's, especially those with fresh water pools in the passenger compartments.

Did you replace with a Toyota factory battery, and if you did do you mind naming the dealer and how much you paid?

 

It's 015B in the A_Standard_PID_US.csv. It's the same as SoC in another list, just goes by a different title.

 

OK thanks. I display it as SOC.

SOC is a more accurate description as State of Charge and not remaining battery life. Of course I am sure you already know this.

 

Bobert, my daughters prius has the same symptoms. It started about a month ago. Her prius would have condensation on the inside of the windows and windshield and now he red car slash shows up on console. It drives fine. So i take it to our dealer and they say cooling system has craped put aNd it will be 4600 to replace batteries and cooling fan. On top of that the dash lights and speedo has been out for about 6 months. They say no warrantee on that either so another 894.000 so grand total. 5500.00. They are freakin nuts. They put new batteries in it 3 years ago. This is ridiculous. Granted it has 245k and is a 2005 model. But i told them hell no im coming to get it "Well sir that will be 49.95 diagnosis fee. Best 50 bucks i ever spent to get it away from those AHose.


iPad ?

 

Ohh sorry guys the question is can i let my daughter drive it without the batteries supposedly getting charged? It Drives fine and it shows the batteries are working on the dash energy monitor. It just has the red car slash warning kindof of to the side of the monitor.
