And again my questions, recommendations and requests :) 1. Why is there no sensor supply voltage on the oscillogram of contact No.4? This is nonsense. 2. Connect the common wire of the oscilloscope to the motor housing. 3. Check/measure the signals on all four contacts and show the results with...

p.s.s. Unfortunately, this question only came up now... :( According to RAVEV RM, the rotor speed sensor is connected as shown in this image https://alflash.com.ua/2019/to_rav4ev/w_sp_sens.png And pin 4 (white wire) is the sensor supply voltage. Is this true or am I wrong...

Thanks for clarification! Judging by the way the pulse repetition period changes in state 3, it is quite likely that the rotor is already rotating in this state. Recommendations regarding this case of using an oscilloscope. a) reduce the sweep time to 5 ms per division; b) set the sensitivity...

Checking the engine speed sensor with an oscilloscope. Thank you for your attention to my request! Your video is a great help to many RAV4EV owners. 1. Please report the conditions/state/mode under which the speed sensor signals had the shape shown in the video. Ign ON/READY ? Transmission...

Strange situation. On one hand, there is no adequate heater control signal from the Power Management ECU, and on the other hand, the heater is not activated under "manual control" from simulator. Just in case, I will ask, is the cabin heater power fuse still intact/serviceable? It is possible...

I can't answer your question, because I haven't checked the possibility of variations in the heater control signal frequency. But I think that a change of 2 times in either direction is not acceptable. It is possible that the cause of the malfunction is that for a frequency of 40 Hz the...

It's not just interference/electrical noise/interference At 22 seconds of this video, traces of control pulses with a frequency of about 40 Hz flicker. But then they also disappear. The reason for their disappearance is a change in the set heating temperature during filming? In previous videos I...

Ok, I assume that the generator's load capacity is somewhat/slightly small. But I consider the amplitude reduction from 13V to 11 not "criminal" and acceptable. My "experiences" of checking the heater's heating elements will lead to recommending an increase in the heating time when checking...

In advance, I apologize for my comments and questions. 1. I did not understand everything from your descriptions. For example. We are considering the issue of a malfunctioning cabin heater. But the information about turning on/off the air conditioner and seat heaters is extraneous and causes...

I strongly advise against applying power to signal lines. 1. This may damage the device to which this connection will be made. 2. It is possible that the absence of PWM pulses with an amplitude of 12V will be understood by the heater control controller/"driver" as the absence of the need for...

As I understand this test result (attach.), when the heating is turned on, there is no control signal on the RMI contact. Therefore, only/solely for the final check/testing of the serviceability of the cabin heater itself, I would try to disconnect the contact from the Power Control ECU control...

Note. The insulation resistance between the stator windings and the stator housing is not the Isolation Resistance* parameter in the diagnostic program. A three-phase voltage is supplied to the stator windings**, controlled in amplitude and frequency by an inverter. *...

There is confusion (?) on the D15 connector with two extreme contacts. But, a) the marking of their wires (W-B vs. W) is known (visible in the photo), b) check the voltage on each of them - only (2) 1* measurements [*update: connecting the oscilloscope to the white wire (W) and activating the...

1. This picture (https://alflash.com.ua/2019/to_rav4ev/cab_heat_w2.png) is only a compilation of images taken from the repair manual of this car. Perhaps you are confusing the "male" and "female" connectors or the front and back sides of the connector. But in all cases, the color marking of the...

Dear Rakesh Suresh, Please excuse my inattention. Cito. Please confirm that this picture of yours shows voltage check on W-B white wire with black stripe (pin GND 1), but not on W white wire (pin RMI)? https://alflash.com.ua/2019/to_rav4ev/d15conn.jpg If so, please repeat the RMI signal...

Questions (²/5 off-topic). 1. In phoro (attach.1). 2. During this check, is the heating system fully assembled and the "Air Purge" procedure performed? 3-4. In attach.2. 5. I wonder if the heating elements of the Quick-heater turn on when the maximum cabin heating is set and under other...

Do a simple Tony test and you will know the actual SOH of your car battery. For example, https://alflash.com.ua/2020/images/217.png or only with TDS soft https://alflash.com.ua/2019/to_rav4ev/degradation_compare.png

Addition. Based on the photo of the PWR voltage at the heater connector, the A/C–IGCT fuse (10A) is Ok.

Quick answer. At this time, if the heater is receiving high voltage, but there is no control signal from the Power Management Control ECU*, then I can only suggest one thing. Check the A/C–B fuse (7.5A) in the Motor Compartment Relay Block No. 2 (under the hood in the right box). I would set...

Dear Sir, please 1. Watch the video I recommended earlier... This is a screenshot of a fragment of it https://alflash.com.ua/2019/to_rav4ev/ac_control.jpg 2. Pay attention to these temperature control buttons... https://alflash.com.ua/2019/to_rav4ev/acfin.jpg * 3. Maybe you will find time to...
