Warning/attention. Sir, pin 14 of the DLC3* diagnostic connector is one of the two CAN bus pins! DTC C1345/66 Linear Solenoid Valve Offset Learning Undone. To perform the initialization and calibration function of the linear solenoid valve (when not using the Techstream), you must use pins 4...

p.s. For reference. Video of a contactor that did not turn on due to the fact that the moving contact was welded into the stationary one Photo https://alflash.com.ua/2019/to_rav4ev/cont_weld.jpg

Clarification. This my video is not an illustration of the malfunction of your vehicle. This video demonstrates that Tesla's self-diagnostic system does not react adequately to some situations. In the bottom corner, there is a video of the synchronous recording of the voltmeter, which shows...

If a pyrocartridge is triggered that breaks the contactor power circuit, the corresponding fault code is stored in the SRS system. Your description does not imply that it is defective. If necessary, and with the help of AnyDesk software, we can look at your vehicle's Tesla system with "four...

A Google search* suggested a link to my video, which shows the short-term appearance of this code while RAV4EV is moving. In this case, the inverter temperature = 40°C (104°F) and the stator temperature = 64°C (147°F). Notes The coolant level in the vehicle is normal and the Coolant Air Purge**...

1/2 OFF. Note. The cause of the BMS_f071 code (alert) may be a critical malfunction in any Tesla system, not just in the Inverter For example, one of the reasons for this code https://alflash.com.ua/2019/to_rav4ev/_f107.png shown in

Spacemonkey43, Thanks for photos. What looks like dark yellow/brown grease is grease that has been washed out of the bearing* and painted by rust of stator The result is shown in Note. In the motor can't get in no other fluid except G48. * https://alflash.com.ua/2019/to_rav4ev/bear_seals_.jpg

The easiest and fastest way is to install the Tesla system diagnostics program and make or buy a cable https://www.myrav4ev.com/threads/help-charging-issue-not-cables-and-probably-not-battery.2632/#post-30891 With AnyDesk or Teamviewer, we can help* in connecting, collecting and analysing data...

It is impossible to measure the actual active resistance of the stator windings using a conventional DVOM tester. The stator current of RAV4EV (delta windings connection) can exceed 500A, so the resistance of the windings is small (to avoid unnecessary losses) and must be measured with a...

Note. IMO. RAV4EV Cabin Heater not use PTC Heater elements Unlike what is shown in

Checking of Isolation Resistance between the stator to Chasis use Megaohmmeter https://alflash.com.ua/2019/to_rav4ev/isolat_resist.png

"Fault threshold" for the parameter Isolation resistance for RAV4EV https://alflash.com.ua/2019/to_rav4ev/isol_resist.png

100% Do you know the meaning/essence/content of the Battery Serial 01÷13 parameters? https://alflash.com.ua/2019/to_rav4ev/1.1.46b.png

Excuse me for 1/2 offtopic. Continuation of the history of this vehicle (checking the stator and its condition) and checking after rewinding the stator at Checking the condition of this vehicle in motion (confirming test-drive) 2 years after repair .

The main cause of bearing currents in electric motors (and in RAV4EV transmission) is the high frequency common mode voltages generated by the converter. Prolonged discharge currents create grooves that reduce bearing life and can lead to premature motor failure. One way to suppress the...
