My 2001 Dodge 1500 failed inspection because the OBD system was reponding. I took it to PepBoys who were unable to read it also after driving the truck.
I took it to PepBoys who also couldn't read it after returning twice and driving
it all over for weeks. I had a check engine light on but it went off after I
disconnected the battery for other needed repairs. The light never came back
on. The truck seems to be running great. I just can't get past inspection
because the OBD is not responding. Should I disconnect the battery again. Is
there a battery that can be replaced. Is there a way to know if it is responding
without bringing it to PepBoys .
did you check the ODB Fuse?
This may help, its for a 2500 but should be about the same. http://www.nwbombers.com/forums/topic/50371-obd-port-not-working/
