If you find certain aspects of your job challenging due to ASD, then by all means - tell your employer, and see what accomodations can be given. Also, if you're known for being eccentric or have displayed what has been perceived as erratic behaviour, then being open about your ASD may help explain your past behaviour and give you more leeway in the future.
If you are getting pulled up by your employer over performance or behaviour issues, there is a right and wrong way to disclose your diagnosis. My strong advice is that once you're told there's a problem, do what you have to do to rectify it, then explain why you sometimes find it hard to maintain that standard. Once your employer acknowledges an improvement (and if they don't, then don't be afraid to ask how them how you're going), they're more likely to see an incentive to work with you on the issue.
You will only be seen as using ASD as a get-out-of jail card if you plead your case at the first sign of trouble, or the first written warning. The more likely result is that your employer will find a way to get rid of you (anti-discrimination laws are only effective against anyone stupid enough to discriminate openly), and will never consider employing anyone they suspect to be an Aspie in the future.
