Here is a very complete description of what this error code means, what could be causing it, and how to diagnose it:

I would not do any sort of software upgrade for a car that is 17 years old. I believe a more traditional repair is in order.

Actually took my car to dealer today, normally go to an independent. They could not find a fault with anything involving the coolant system. The ECM was not able to be upgraded. Since the car has been checked by two experts and is running fine I may get a code reader and turn the light off myself when it gives that code. Thanks.
