OBD Not Receiving Power / Not Working

Check fuse 15 under the hood

If you mean, the state OBD computer did not connect or DID connect but did not receive any data, it seems that this is a problem with updated software in some of the state systems this year. Try plugging in your own OBD reader, or going to an auto parts store and seeing if their reader can get data from the car. If they can, call your state testing agency.

I know that in New York, they are going nuts with many makes and models of cars not receiving data. There is an employee there who has helped several owners, they are working it out slowly.

Carbuff is correct!!! To be viable, the module communication speed needs to be 62.5 Kbps (kilobytes per second) or higher. Modules that use slower communication protocols such as CCD, PCI, J1850, and ISO-9141 are too slow to be effective for making data recordings.

The way I understood it...when they plugged into the OBD port, nothing was being sent from my car to the their computer.

As others said -- go to Autozone or any other parts store that offers free code read out and have them read the codes. If they can -- then the problem is state software (a number of state seem to have changed their software and this has been causing headaches).

If the autozone reader can't read codes, then the problem is with the car.

I went to Autozone last night and the reader said "No Codes". But that makes sense because I don't have an issue that would be resulting in any codes.

I'm in the North Texas area so I wonder if it's an issue with the service stations computers.

Try to purposely set a code and see if it can be read by the service stations and Autozone.

Sounds like a problem with the service centers OBD reader from the investigating you've done

Maybe someone has already said this but here goes. Disconnect the negative terminal on your battery for a few minutes and then hook it back up. You should get a P1684 code and then a donE when you check, using the key dance method.

Sounds like it is an issue with the state's testing software. You might want to contact your state's DMV who manages the testing program.

Problem solved. It was a problem with the state equipment. I went to a Firestone and it worked just fine. They mentioned that it happens from time to time and when it does, they have to call the state and have them recalibrate their equipment.

:Thumb: Glad you got it all figured out.
