i don’t have a lot of SR experience, but i imagine it has the same purpose as a KA ecu, you use it to pull the codes and the lights on the hole to the left of it will light up to give you the trouble codes.

It’s a series of short and long blinks, write down the number of each and that’s your code. 5 short 5 long is good. Anything else indicates a problem. The code lists are on here.
