Hello. Welcome to Just Answer. Please allow me to assist you. This car has a self-diagnostic system. Is the car available?

Please locate the round diagnostic connector under the left side of the dash. If it has a cover, open it and locate the terminals E1 and Te1 as indicated on the lid's label. Then we will proceed. If the under the dash does not have a label, look under the hood for a small rectangular diagnostic box with a plastic lid. Locate E1 and Te1. Then let me know when you are ready to move forward.
