A drawing of the structural diagram of the cooling accumulator was shown at the Toyota training. But this is not a photo of the under hood space. They are easy to find on the site using the search. https://www.myrav4ev.com/threads/another-dead-rav4-ev.2582/#post-30340

Sir, this is my video answer to your question about the battery heater. And about the location of the DC-DC converter, you could find out from this link, which was recommended earlier https://alflash.com.ua/2019/to_rav4ev/bat_cool4.png

Ok, if there are no traces of coolant on your speed sensor, for example as in then several preventive measures are possible. Only replacing the seal on the right side of the engine. The advertised modernization/reconstruction/upgrade of the engine cooling system, the long-term consequences...

An inexplicable situation with this RAV4EV, which has no fault codes in the Tesla system* https://alflash.com.ua/2019/to_rav4ev/no_codes.png but in the Toyota system there is a non-erasable code P312f https://alflash.com.ua/2019/to_rav4ev/p312f.jpg...

Take a look at the possible consequences of coolant getting into the engine

Please illustrate between which contacts of the charging port connector the resistance is zero and please show a photo with the result of this measurement

Yes, as show indescription of checking this fuse in T-SB-0111-14. And in compliance with electrical safety regulations.

Sir, You forgot to mention the additional costs of reflash the Tesla "brains" of the ee gen1 charger

As far as I know, a) versions 1.1.42 and 1.1.46 have the same method/way of communicating with the Tesla system; b) there is a simple way to "reanimate" 1.1 42. https://www.myrav4ev.com/threads/tesla-powertrain-diagnostics-tpd-v1-1-46.2602/#post-30654 But I'm sure that the reason for the problem...

Is the network card working? Correct cable pinout? Is TCP/IP setup correct? Is the configuration complete? Color of the ball in the lower left corner? Screenshot of the window with menu blocks when connected? We can watch it together using AnyDesk...

Today, when remote diagnosing RAV4EV in Tennessee, another idiocy of version 1.1.46 "surfaced". In the Gateway cloning menu, the option to not save useless heavy log files (more than 200 megabytes each) disappeared. As a result, I had to download hundreds of MB, not about two. And not less than...

Thanks! The results of these checks are OK.

Thank you for such inattention to my request. Dear Sir, I do not know (I hope I will survive this :) ) the results of checking the resistance between contacts 3 and 4, as well as between contacts 3 and 5 of this connector with the negative terminal of the 12V battery disconnected...

A great step in the right direction. We have already avoided a needless purchase and replacement of the pump. :) Moving on. Is it possible to check the fuse for the cabin heater? The check is described in T-SB-0111-14 "HVAC - Heater Inoperative" (let me know if it is needed). Perhaps this...

1-2. Yes, Thermal Control ECU, receiving a feedback signal*, "knows" that the pump motor is running with a duty cycle of 30%, shown in your screenehot. * 3. Please explain what "disconnect D6" means and what does DC-DC Converter have to do with the codes in the screenshota? I suggest doing...

This heater is "well hidden". Follow the hoses and you will find it. https://alflash.com.ua/2019/to_rav4ev/bat_cool4.png Update . The specified fuse is located on the main board of the DC-DC converter https://alflash.com.ua/2019/to_rav4ev/fuses.jpg 1/2 Off Battery Heater Current p.s. It would...

Take a look Note. DC-DC converter assembly enclosure and supplies high voltage from the electric vehicle battery assembly to the compressor assembly with bracket, battery coolant heater (uses 20A fuse, the bottom one in this photo*) and No.1 heater with bracket sub-assembly. The DC-DC...
