I mentioned this program for a quick check BEFORE removing the battery. As shown here , Modules in the garbage, if the battery is disassembled, can be checked by connecting directly to each of the 16 BMB, as shown in If not, then to the BMS connector through the top hatch...

I would venture to suggest that before removing the battery, it would not hurt to check its condition* and the condition of its cells and modules** using a well-known program for smartphones and others soft*** * https://alflash.com.ua/2019/to_rav4ev/bat_data2.jpg **...

Gigavac contactor's coil resistance is approx. 3.1-3.2 Ohm? Not. Have you compared the datasheet of the contactors of both brands?

Can you show a photo of the state of contacts similar to these photos? https://alflash.com.ua/2019/to_rav4ev/__cont_prof1.jpg https://alflash.com.ua/2019/to_rav4ev/contactor_bad.jpg

The likelihood of reliably checking the rotor temperature after this upgrade is practically zero. The only attempt to check the rotor temperature is described in https://www.myrav4ev.com/threads/ldu-rotor-temperature-monitor.2641/ IMHO. It was not in vain that Tesla engineers provided liquid...

For Clarification. Quote from RAV4EV RM (Doc ID: RM000005CIQ00FX) https://alflash.com.ua/2019/to_rav4ev/f011.png HTH,

1.Quote from RAV4EV Repair Manual (Doc ID: RM000005CME009X) As I understand, "Hardware detected overcurrent in the high voltage positive or high voltage negative circuit* of the electric vehicle battery assembly" (During charging). * https://alflash.com.ua/2019/to_rav4ev/hvlines.pdf 2. In the...

Before this, it is necessary to remove the effects of coolant entering the stator and replace at least one ceramic bearing. It is useful to check other bearings and insulation resistance between the stator windings and the stator housing.

It is curious who or what in this situation will dock the exchange of data between the BMS board of the donor battery with the patient's Gateway ECU. In addition, the RAV4 EV battery has 92 cells*, while the Toyota bz4x has 96. * which are serviced with 16 BMB units...

This video shows good movement of RAV4EV despite the fact that the Isolation Resistance parameter = 0 kOhm (!)

Pay attention to this list of possible causes for code BMS_f063 https://alflash.com.ua/2019/to_rav4ev/bms_f063.png Statistically, its most common cause is faulty contactor(s) https://alflash.com.ua/2019/to_rav4ev/contactor_bad.jpg

First of all, this RAV4EV needs 1. Replacement*) - rotor seals with Teflon seals installation - both hybrid/ceramic bearings - probably transmission bearings 2. Checking - insulation resistance between the stator windings and the stator housing using a megohmmeter - condition of the rotor shaft...

Note. Tesla's opinion on this codes for RAV4EV https://alflash.com.ua/2019/to_rav4ev/di_w008cause.png *) IMHO. If the vehicle is in IGN ON the failure is reported as a FAULT (for example: DI_f020). The vehicle opens contactors, or keeps them open. If the vehicle is in Drive Mode, the failure...

Absolutely yes. This photo is from the description of Toyota about tesla's sofrware TPD 1.1.42: https://alflash.com.ua/phpBB2/download/file.php?id=2583 For example, https://alflash.com.ua/2019/to_rav4ev/tesla_vim_s.jpg Some users insert the adapter board removed from its housing into the...

Have you tried making a cable https://diag.alflash.com.ua/wp-content/uploads/2024/04/cable_w-696x315.jpg yourself, using this connector https://www.amazon.com/gp/product/B083FF4Y85/ref=ppx_yo_dt_b_asin_title_o00_s00 and a regular RJ45 patch cord?

I sympathize, get well soon! And thanks for the feedback.

On speed sensor of your photos there is grease washed out of a closed hybrid bearing and obvious traces of coolant :( A similar example is shown here Links to the continuation of this story and happy ending and rechecking two years later in its description

Having the TPD diagnostic program, you can easily determine the level of degradation or SOH of HV battery as shown in In addition, using your phone you can analyze the cells voltages during charging

What was the stator temperature during this rotor temperature measurement?
