Hi,

This vehicle isn't offered in the US, but I will try to help. If the indicator light is coming on and flashing, there should be codes. Take a look through this link. It explains how to retrieve OBD1 codes from vehicles made before 1995. Try this and let me know what you find.

Let me know what you find.
