My Mazda 5 is suffering with these symptoms, will try this when the weather improves abit.

mine used to connect to torque app . but now it doesnt work.only in one specific app it does connect to ecu. which i can't explain why?? i've replace the ddapters . and both works fine with torque pro in another car. i guess there's something wrong with my obd port itself. i'll give atry though. thanks!!!

This is a great, helpful video! Having same issue with a 1996 Jeep Cherokee. Hoping to try this. Hoping it'll work for my Jeep. If it doesn't, what else could it be? Already tried a different computer, but that didn't solve the issue. Thanks!

I have a similar problem with my 98 cabrio. My scanner has power but even if the check engine light is on my scanner doesnt pick up codes

Thank you that was very useful as I have the same non communication problem on my Range Rover 4.2 supercharged. I hop mine is an easy fix like this one. Bet it ain't lol

I have a similar scanner and when I plug it in and press scan it’ll load and then it will just revert back to the main menu after it’s finished loading. I don’t get an error and failure to connect message. Battery is new, and the pins are fine. Any tips?? Thanks. Edit: I don’t currently have a CEL on however part of my cluster lights are burnt out so I don’t know if the CEL is on or off.

@DCF Garage I noticed the trouble code on your scanner was P0741 and it's on a GM vehicle. What did you do for a fix on that code? I have a 2008 Chevrolet Colorado with that same code.

I believe that is likely a bad torque converter. There is a sensor that can also go bad, but normally it’s the TC

My 2006 Frontier, same problem. Power, no communcation with DMV. Told by garage today they found that a pin in the Data Link Communicator, or the OBD2, needed tightening, when they t4ried to plug one into the other, the pin wasn't making contact where it should. I was told they tightened this one pin, probably #16 which is the communicator pin from what I've read. So that is the problem I had. It is fixed, as of today. Happened last year too.

Excellent video dude, you save my life 🙂

Thank you for this video I have an OBD2. The blue piece, when I connect it to the slot, lights up red, but when I start searching for malfunctions, it does not respond and shows me a message that the piece has not connected to the computer, and I do not know what is wrong.

would this ground wire from the obd2 port affect my check engine light not coming on or should i look somewhere else

have a similar issue on my 5yr old Tacoma. If I try to wiggle the harness while plugged into the obd2 scanner, it'll lose connection and the scanner screen will flicker. I'm going to try this.

Only need key out and to pull the cigarette lighter fuse under the hood which will kill the power just in case you touch 12v+ to a ground.

Start with the basics. Make sure the pins are good… especially if it’s and old car. If that’s not the case, then your problem might be the ECM itself

Every video I've found on obd2 not connecting has the same outcome. Very basic and of no help. Connector pin drag test was first thing I thought of. And huge problem with anything that has a connector. And there are the ones that find a blown fuse. That is eliminated when the scanner powers up. Got power. Got ground. Pins are tight. No data. Can bus voltages seem to be right, from what I can tell. But checking resistance between two canbus wires finds no continuity. Could be due to no access to get good connection. Not even sure what sort of system/network a 2000 xkr has. Can't find hardly any info about it. Go chasing after can bus likely has nothing to do with actual concern. Just need to get codes and read data

Not necessary. It will be hard to diagnose with it disconnected. If you do one wire at a time, there's no risk

I wonder if GM offers a OBD pin repair or replacement kit Most Jap cars do not you have to buy a new harness.
