There are a number of possible problems that can occur during voltage outages. Initialization of windows and top will take a simple manual reset. I have seen an uninitialized steering angle sensor set off BAS/ETC codes that required a scanner to reset.

I have seen D2B configurations somehow lost resulting in phone or CD problems. I have seen the variant coding lost in the AC controllers which is easiest reset with a scanner.

The 99 models are a fair bit simpler than the 2000- ones. No specific programming is installed on those cars, but many variants can need resting.
