Hello,
I Have problem with my Leaf 2018. On display it shows "Key System Error- See Owners Manual".
When this message shows: the steering wheel is very light, seat belt signal doesnt work, miles/kilometers doesnt shows, the instrument it doesnt show either how fast you drive it.
This problem came when i took out the instrument cluster to fix the glas, and when I install it back i didnt take off the battery (-) cable. This warning message ("Key System Error- See Owners Manual").
It looks like it have to be activated the car but i dont know how?
I appreciate it if someone can help me with this and give me instruction about to fix this problem?
BR
