DATA LINK ERROR...

My 2007 basic tacoma with 2TR-FE engine is not providing any data from its data link connector or OBD-2 connector. The truck runs fine with "NO" CHECK ENGINE LIGHT showing. I was due for smog last month but failed due to this data link error.
Can somebody share me any idea of how to fix this...Thank you.

 

Did you get it double checked somewhere else? Could be on the other end.

 

Thanks, Nirvana. I might have it checked somewhere else...i was just hoping i can do something that might fix this...to avoid that expensive electronic repair.

 

Seems really strange that it wouldn't read at all. I'm sure it's happened before I've just never heard of it having plugged scanners into...too many cars to count. Hope it's something simple, digging into wiring harnesses gets tedious and expensive fast.

 

Did you check the OBD fuse?

 

Good call. Custom tacos had a pretty good run down on it. The thread is 1st gen and I just did a quick scan but it looks like it may be helpful. http://www.customtacos.com/forum/127-1995-5-2004/149622-obd2-port-doesn-t-work.html

 

Scan tools are powered. OBD test checks for battery voltage at the connector. An open fuse will cause the " no communication " error.
