Question: For the Type 1 socket does the plug latch need to be commanded to lock, i.e. message sent?
My LIM doesn't activate the latch nor when plug is inserted nor when charge completed.
After cracking open and fixing the latch cam mechanism, the latch feedbacks 1kOhm when unlocked, 11kOhm when locked.
(Fun fact, on Type1 BWM latch, if the latch is engaged without the plug inserted, there's a small edge on the cam that presses the button and makes the FB read 1kOhm just like when unlatched - someone posted good pictures)
I also tried sending the OBD reset as somebody suggested, but without a luck.
The lock status always remains in error state according to LIM. LIM however reads the wall charger info, pilot, gives a-ok to charge, which I use it to kick BMS to wake AC charger via CAN and the charger wakes up. Though I don't have HV connected to the charger yet, but the charger starts sending back healthy status messages and detects AC on input. Wall charger says the car is charging.christoph wrote: ↑Mon Dec 12, 2022 6:27 pm Meh, my LIM stopped locking the charging port when I plug in I measured the lock, it’s 1 kΩ unlocked, 11 kΩ locked as it should be.
Problem solved by sending a OBD reset:

Charge port LED is white when nothing plugged in; slowly pulsing blue during charge and green when finished.
Logs..
Plugged in.. Pressed stop charging button.. Unplugged.. Edit: I also put a scope on the latch motor outputs of the LIM. Doesn't look like LIM is even trying to kick the motor.
