What are the fault codes in the VESC tool? Could help pinpoint what’s wrong.

This.
Rebooting the ESC clears them, so look before you do that.

Maybe try flashing the bootloader on the bad side using the good side. @abusfullofnuns was forced to become an expert on this recently.

I powered the board back on after a few minutes and both motors worked on the bench for a few seconds before the left motor stops working and I have a red led in position 1 flashing 6 times then pausing briefly before repeating the 6 flashes.
How should I deteine the fault codes in the vesc tool?

Aha! It says fault: over_temp_motor
Bad temperature sensor in the motor?
Edit: it also seems like the motor that is throwing the code has much less torque than the other

Ran motor detection thrice with the sensors disconnected.
The first time failed and said “CAN detection timeout”.
The second time it was “successful” and had one motor at 40 amps sensorless and the other at 67 amps and sensored.
Third time was pretty normal and displayed sensorless for both motors and 67 and 66 amps respectively.
I don’t feel good about this.

Try swapping the motors (connections only, you don’t need to unbolt them) and see if the fault code swaps sides or not.

It’s strange because I don’t have any lights on side B at all but the motor still spins
I will try the motor swap
Any good instructional resources on this? I can’t find anything.

Trampa did a video. Let me try and find it.

Thanks everyone for the advice. I managed to resolve the issue by removing the temp wire from the sensor wire extensions that I’m using.
No temp wire, no fault code.
I did flash the side B using side A, but I’m not sure it was necessary.
Broke my personal speed record today at 36MPH. (~58 km/h)
I’m so glad to be back on the road and still running both motors sensored.
Stay safe, dudes.

@hardunclejohn if i am doing 4wd canbus with 2 spintends then should i use a 4 way canbus or just a normal canbus between the 2 sides? i am currently using just a normal one between 2 ports and am getting quite unreliable canbus feedback from my telemetry like metr pro and ble module
thank you

hello
is there any guides on how to flash the original firmwhere?
just want to try flashing as i still cant connect to mobile app
ok cancel that just managed to connect to the mobile app 
thanks
One CAN cable from the front to the back dual esc is enough.
If you don’t get a good connection check your jst plugs an wiring. Might be a broken wire.
Double check with a new cable if you have one on hand.
Also make sure your CAN cable isn’t routed close to power or phase wires. Shouldn’t have a big influence, but better to do so.
If connection is still shit, you could use a twisted shielded wire and put the shielding to the ground connection of the CAN plug on one esc. Not on both sides please.
