i have a 96 volvo 960 wagon. i took it to get it smogged and it failed. i replaced cracked hoses and did a tune up. berfore i went back to retest it the battery died. the car has an OBDII and since the battery died it erased the computer. now the car has to learn back everthing again. ive talk to a lot of different peolpe and some said all i can do is drive it and others said there is something to reset it. they just arent sure where it is located. is there something to reset it?

 

You have to drive it till it gets to the Ready status.
