Title says it all. Computer at the shop could not talk to the obd2. My code reader could also not talk to the obd 2.

 

hmm i went to advanced auto and had them read mine, then i just bought one of my own.. works fine, Tells me all the codes some are LR exclusive but downloaded coldes with discriptors from the net..Its not reading ANYTHING? can you be a bit more specific ? OBD2 reader does not power up on plug in ? there is no direct connection? it wont read a code ? thanks bro

 

Sounds like your OBD port is dead, meaning its not getting power for some reason.
This has happened before but they never posted back with the cure.
Start by checking ALL fuses.

 

Are there any fuses other then the ones under the dash?

 

Yes, under the hood.

 

I believe you can check the voltage at pin 16.

I just got off the phone with him, I think its strange that the OBDII isn't reading and his IACV isn't working [possibly due to the ECU.]

I think he should pull out his ecu and check for corrosion and water.

 

Good idea Spence.

 

Im kinda just talking for him, I think hes busy working on his ecu. I know it seems like I dont have a life lol. Im being forced to watch the saints game, or at least sit here and pretend to watch.

Anyways, he took apart his ECU and it did have mud and dirt in it. He is cleaning it up I believe and I offered one of my spares to him.

 

I'm confussed I've heard people talk about the ecu being under the hood but mine is in the passenger under dash. did they move them, I know mine being a 94 there are a few differences than the obd2 models.

 

hmm.. I dunno what does the rave say?

In everyone I have ever seen its under the black cover next to the windsheild washer fluid.
