Hi I am having an issue with my Panda's OBD2 Port, it seems to be totally dead. Is there a fuse that it uses? I have an yellow triangle with exclamation mark illuminated on dash and stop start is nor working, but driving fine otherwise, but I have been unable to diagnose as the port is dead. Any help will be very gratefully received.
Don't know if this will help you, but if you have multimeter and are careful, it should tell you if you are getting power and earth in correct places. I tested using a "breakout box" which is a safer way of doing it.
It may be best if you read up about it first before diving in.
