My Tesla Model3 SR+ LFP will not charge!

[csergio01]

Hello everyone, my 2021 Tesla Model 3SR+ is not letting me charge anymore.. To an extent. For example, whenever I try to plug in my Wallbox 40V charger in the car, the actuators make a clicking sound about 5 times then the T logo stays a solid blue for a couple of seconds then turns red.

By that time I decided to try teslas provided charging cable with the 110V attached to it. This time in the vehicle it says ”Charging Equipment Not Ready”..
I thought my house was the problem but I tried the teslas connector at my friends 110v outlet and that too did not work showing the same warning previously.

Interestingly the vehicle will charge at a change point+ Nearby. But can someone explain why is that?

Anything is extremely helpful, I do have an appointment with a mobile tech sometime this week and have a roadside service claim open so this problem can get prioritized.

(Note; I do live in Alaska. So I do not have a supercharger within 100miles of me and don’t have a service center nearby, only mobile techs)

Maybe check the pins in the charging port for any debris or obstructions?

go to selfservice car wash and just hose it out in case theres crud in there.

Get one of these to confirm your 120V outlet is properly wired. If your ground is not present, the Tesla mobile connector will not function.

No debris, nothing obstructing it clean as can be.

Yes, so come to find the ECU was what failed and needed to be replaced just as I suspected! What was also nice was the replaced ECU was also a CCS adapter enabled one too! So I got a two for one !!

Our amazing mobile technician we have up here replaced my faulty charging ECU (which I had suspected) and voila! Everything finally works and it wasn’t my at home charger or charger which I thought it was.

But that’s not all, I had a feeling in me that this was also a CCS adapter upgrade, so I went to check after the fix and to my surprise .. my vehicle before when it wasn’t fixed went from “CCS not Enabled” to Enabled!! Sooo a basic ecu upgrade is all that’s needed to get CCS adapter support. Hope this helps anyone!
