No scan tool is needed for this car, you can read out the codes manually. Here's some info:
Reading Codes:
Code Descriptions:
requires a special scanner. it is better to let a shop scan it for you and tell you the issue and give you a bid. there will be no way of checking the trans as this is way too early for trans codes. a trans shop will help you with that part of the repair.

It's a little difficult to find a scan tool for your 1993 volvo, it's too old. Better to know the obd port type of your car.
