High Battery Temp Power Output and Max Speed Limitedd

Hello everyone,

When driving my 2012 RAV4 EV the other day, I got the following
dreaded messages:

Check EV System
Have Your Vehicle Checked by a Dealership Immediately.

High Battery Temp
Battery Cooling Now
Power Output and Ma Speed Limited
Please Wait for Full Power

The car has only 44K+ miles, and it hasn't been driven
for the past several months or so. The last time it was driven,
there were no signs of any problems.

First question is how can it develop such a catastrophic failure,
while it's been sitting in the garage undriven for the past several
months?

Second question is, if I get one of those OBD diagnostics tool,
will it help me to isolate the source of the problem?

Any advice would be highly appreciated.

Thank you very much,

Peter

1. Check coolant levels:

2. One of the most likely causes of such a malfunction is a breakdown of one of HV battery cooling water pumps.

3. For consultation and/or remote diagnostics of RAV4EV Tesla systems, use this form:

alflash,

Thanks very much for your reply.

I checked all the coolant levels, and they are all normal.

What kind of consultation can you provide? How do you provide the consultation, and how much do you charge for the consultation?

Thank you

Ok,
My Consultations about RAV4EV
1. Is free for charge,
2. They are based on the successful remote diagnostic experience of over a hundred RAV4EVs in locations from Vladivostok to Vancouver and California (e.g. http://www.myrav4ev.com/forum/viewtopic.php?t=2530 )

p.s. Using this mode

check the 12V battery voltage with IGN ON and Ready modes.

p.s.s. You can use (for read DTC) Generic OBD-II scantool?

alflash,

Thanks very much for your generous help.

I watched your diagnostic Youtube video and accessed the secret menu on the navigation display. The battery voltage is normal.

Yes, I used OBD2 tool and got a P312F code in the EV Propulsion System. What does this mean? What should I do next?

Thank you very much,

Peter

This code is only evidence that a malfunction was detected in RAV4EV Tesla system

This code can be erased by disconnecting the 12V battery (for 5 minutes) with the ignition off or by following procedure

Can your scantool read Freeze Frame data

alflash,

I'm glad to know you're able to isolate the problem to the Tesla side.

Ok, I displayed and saved the Freeze Frame data into a .TSE file.

How can I send you the .TSE file through this forum?

Thank you,

Peter

alflash,

I couldn't figure out how to send the .TSE file to you through the forum, so I've inserted the four screen shots here:

Hope you can find some useful info from these screen shots.

Thank you,

UPDATE
=======

I followed up with Vladimir Leshchenko at https://alflash.com.ua/index.html

He performed a remote diagnostics and immediately found the problem to be
a failed powertrain coolant pump.

In a previous post, https://www.myrav4ev.com/forum/viewtopic.php?t=2484,
dfergenson mentioned he replaced his powertrain coolant pump with a Tesla
coolant pump he had purchased on eBay, part number 6007376-00-E.

While shopping on eBay for a used pump, I found what seemed to be a slight
discrepancy in the Tesla replacement part number.

After bringing up this discrepancy with him, he confirmed that the correct part number
should be 6007367-00-E.
