I had my abs comp fixed and i put it back in and the lights are still on. i have the battery disconnected now and letting it sit. I looked in the haynes chilton manual and its says an odb scanner can show codes. I have a snap on mt 2500 scanner but general odb .so im wondering if a different one will scan them. any suggestions?

 

Some of the Snap On scanners read ABS codes and others don't.
Some Volvo Specialist shops have the scanners to clear the codes.
