Hello,
I recently removed and replaced my 2018 Model 3’s radiator, and in attempting to follow the service manual procedure, tried to use the service mode>thermal actions> ”start thermal fill/drain” as well as “start coolant fill/drain. Both of them gave errors that “they could not run, and to check that another thermal test was not in progress” (it wasn’t) so if I then ran the “Test Thermal Performance“, it would run and complete the test successfully- I could then run the fill/drain options, however it says when you start them that they will run for 50 minutes, but within about 5-10 seconds they switch from “running” to “routine passed” and the coolant system status quickly switches from “not ready for fill/drain” to “ready” then right back to not ready.
I ended up just running the vacuum coolant filler while doing a couple of thermal tests, and seem to have gotten the air out of the system, but the thermal test only lasts about 30 seconds, so I’m not able to pull a vacuum on the system for the full 3min, 2 times as instructed in the service manual.
Does anyone know if this is the correct and expected operation of these functions, or am I missing something? The service manual says the coolant system status may be “not ready” if the drive rails are energized, and to de-energize the drive rails to complete it, but doesn’t seem to explain *how* to de-energize the drive rails. It warns of pressing the brake to start the car, but you have to unlock the gateway to start the fill/drain modes, which involves putting your foot on the brake and energizing the rails (I think)?
Thanks in Advance!
