I have a 2018 LS XR 4155C and it has a OBD II port on the lower right side of the steering console. I used a very inexpensive code reader I purchased from I think Harbor Freight to read the error codes and it read them without trouble and was able to clear the codes as well. Of course resetting the code did not solve my problem but it was worth a shot.
thanks mines the nexlink nl 102 it should work
