1. To double check, I would connect an oscilloscope and take a photo of data from remaining two contacts. For example, to check whether the heater has 12V power 2. An example of a control signal when the temperature in the cabin is higher than the set temperature and the heater does not work...

1. Was there current flowing through that wire when the zero button was pressed? 2. Photo of readings of the current clamps stationary after zero calibration after turning on the interior heating? https://alflash.com.ua/2019/to_rav4ev/frame at 0m20s.jpg The heater was tested with the heating...

I apologize for the ambiguity. I corrected it as best I could Update. https://alflash.com.ua/2019/to_rav4ev/cab_heat_w2.png I don't know if RAV4EV has AC drying mode.

1. My worst guesses were correct.:( Unfortunately, you did not listen to my recommendation to connect an oscilloscope to the connector (D15*) and check (compare with the example) the cabin heater control signal. Therefore, at the moment we do not know whether this control signal comes to the...

Video "Screen Recording 2024-10-06 221416" is no sign of current flowing through the heating elements of the cabin heater. However, there is noticeable current consumption by the fan and possibly the PTC quick-heater*. *...

Ok, ...At the same time it would be interesting to hear and see the condition of these bearings (especially the hybrid and input shaft) during a simple bench test. Their noise level when rotating in the hands without load. Something like what is shown at 20 second of that video from my previous...

p s. Question: Were the parts/bearings that were replaced returned to you?

Сэр, я НЕ просил подключать осциллограф к плате управления нагревательными элементами! Я никогда не делал такой проверки/подключения. И вам не советую! Я предложил подключить сигнальный щуп к контакту RMI разъема D15, а заземляющий щуп, например, к контакту GND1 или к другой "земляной" точке. Я...

So when current flows, the mechanical parts of the motor start moving, starting from the rotor and all the way to the wheels! Or you hear extraneous sounds when you press the accelerator slightly when the car is stationary. for example, with the handbrake activated and the front wheel...

Ok. Let's repeat it again. 1. Since hybrid bearings use ceramic balls, they are much less susceptible to electrical erosion. 2. The brush was always installed on the gearbox side to protect the input shaft bearing. 3. Electrical erosion may not appear until many tens of thousands of miles...

Excuse me, but three questions. Why??? Especially why, if from the right wheel side? What problem do you want to solve by installing this brush?

vs. vs. all bearings of RAV4EV Motor Asembly (there are 7 of them): https://alflash.com.ua/2019/to_rav4ev/bearings_seals.jpg ? Condition of the rotor spline end? (photo). Under what driving conditions is the noise heard? Can we listen to a recording of it?

370V × 4A ~ 1480W(!). This is the power emitted by the heaters. Unfortunately, the oscilloscope readings are unclear/incomprehensible/inexplicable. Please, describe/show the connection points of its signal probe and ground probe. Does the current from the battery change when setting different...

1. Note. Tesla does not use the usual brush design (photo2), but the so-called "distributed" brush (photo1). The thickness of its thousands of "hairs" is approximately 0.02 ÷ 0.03 mm, the clamping force is negligible and, as a result, wear is much less. IMHO. I assume that installing a brush...

Do you know the results of the actual/real SOH test of your HV battery? For example, https://alflash.com.ua/2020/images/217.png

Yes. https://alflash.com.ua/2019/to_rav4ev/cab_h.jpg

There is no need to perform "thermal torture" similar to this :) You can easily see/determine the current that the heater consumes when turned on by the current surge from the HV battery using the program (video in the previous answer). I assume (IMHO) that turning on a low heating...

Questions. Before the current started flowing, was Zero Point Calibration done? What were the readings on the screen? As Reference. RAV4EV Cabin Heater current at maximum load (with almost 4 kW):

If the heater fuse is in good condition, if there are no such burns on the connecting contacts (attach.1) https://alflash.com.ua/2019/to_rav4ev/1contact.jpg if the IGBT transistors are in good condition, if rats have not chewed through the power wires of the pump of this heater (attach.2) if...

Perhaps not the best (not the most civilized) way to connect oscilloscope probes, but simple, proven and without damaging the insulation of the wires The needle/pin is inserted between the outer insulation of the wire and the rubber seal of this wire at the back of the connector. Example in this...
