How to Connect Your Eonon OBD2 Reader to Your Head Unit

[@sreville]

Basic, yet essential information and straight to the point, love it...thank you!

[@AllThingsOverlanding]

Thanks!

[@jaxsonhayes1164]

Awesome video only thing im hung up on is mine is asking for a code, not exactly sure what it is or how to get it. If anyone has any tips it would be appreciated

[@AllThingsOverlanding]

Thanks! It's been a while since I installed that, but I feel like it's maybe 12345678 or 0000 or something like that. I'm actually not sure that I had to put in a code when I did it, but maybe I did? Wish I had more info for you. Not sure if their support will be able to help? I did some googling and they do have an email if it helps: [e-mail]. Good luck!

[@juleshenhunt9956]

Thank you!!! This saved me a lot of frustration.

[@AllThingsOverlanding]

Awesome! Glad it was helpful!

Hello, I was considering buying this, but someone told me that the bluetooth OBD's have some lag when you are using it to check torque and Power. Is this true ? Would you recommend the Eonon OBD2 scanner?

[@AllThingsOverlanding]

Hey there, good question. Honestly, I am not sure if it has a lag for monitoring power through Torque. I pretty much only use it when I have a silly check engine light pop up so I can clear it.

[@simplistic5930]

Late reply but it depends on the scanner itself, the one I bought 3 years ago logs MAF and some other sensors reading like 1-2 times per second so it's good enough. Torque has setting that accelerates the response and it works in most cases

[@jacobwilson5279]

Hey fletch, nice short video. Does your head unit have built in steering wheel controls for volume and call futures or will you be adding an aftermarket steering wheel control adapter? If you do an adapter, a video on that would be great! Keep up the good work.

[@AllThingsOverlanding]

Hey Jacob, thanks! My rig doesn't have the module for steering wheel controls. I generally use car play and don't touch much in the way of controls, but if I do, I'll definitely make a video of it. I bet there are a lot of walk throughs on thenewx.org or clubfrontier.org though!

[@fordhummer189]

Hi is the obd II always plug will not drain battery

[@jsturgillrn]

It does control steering wheel functions and also supports Bose. I never dreamed it could make factory Bose sound even better but it does. I got the Q80pro but basically the same unit

[@smith27uk]

Thanks, was wondering why my eonon wasn't finding my eonon obd reader, wish i'd found out before my engine sprung a leak and overheated, I have one of those stupid cars that doesnt have a temperature gauge !!!!

[@golirasmonk]

How do you plug it in though? I can't find any connectors behind the display.

[@AllThingsOverlanding]

This plugs into your OBD two port in your vehicle, not the back of the head unit. They are generally down below the steering wheel and under the bottom of the dash.

[@SethBerry79]

I'm assuming it has to be the OBD2 reader that is supplied by Eonon, because I have a Veepeak and it refuses to connect. It finds the reader no problem, but they just will not hook up.

[@AllThingsOverlanding]

That would make sense.

[@danteelander1491]

can the head unit be connected to 2 BT devices at the same time?

[@AllThingsOverlanding]

I don’t think so?

[@zain19]

Are you able to erase the code to turn off check engine light with this obd reader?

[@AllThingsOverlanding]

Yep! I sometimes get emissions codes from my cheap O2 sensors and I just wipe them off easily with the Torque app on the headunit connected to the OBD sensor. It’s great.

[@newskillsnewyou]

Question. There are several torque apps. How do I find the real one

[@AllThingsOverlanding]

Good question. The one that I selected and am using in the video is the one called "Torque App: Car Check, Tracker" with the yellow engine with the word "Check" in the middle of it and "TORQUE APP" in red below the yellow engine. Hopefully that helps!

[@Vibolhuynh]

I need your help installing the backup camera that came free with the head unit. I followed the instructions on how to install it but it doesn't work. I don't know why. I check the connections 3-4 times and it seems to be connected properly. Please help! Thanks.

[@AllThingsOverlanding]

That's weird. I didn't have any problems when I installed mine. Have you tried their customer service? Or, maybe you got a bad backup camera and you could return it as "non-working" if you got it off Amazon and select the option to send you another of the same thing. I've had that happen with some headlights I ordered and they're pretty great about shipping out a new one to you which will often fix any issues.

[@Vibolhuynh]

@@AllThingsOverlanding Thanks!

[@ginamariewood]

What is the map option in the app? It's a scanner I thought.

[@AllThingsOverlanding]

It's been a little while since I used the OBD2 reader since I have a new truck now, but I'd guess MAP stands for the Manifold Absolute Pressure. Here's a brief explanation of what that is if it helps: obdcore.com/symptoms-of-bad-map-sensor-troubleshoot-trick-guest-post/

[@fairplayer916]

So when I try to connect the OBD2 unit to my Enon, it fails. And if I try connecting it to my cell phone directly, it asks for a pin. Tried 0000, and 1 2 3 4. Not sure what's going on with the little bastard

[@AllThingsOverlanding]

Are you connecting it via the "Torque" app on your Eonon? That's the only way I've every connected mine. If it ever shows as "no connection found" I've just unplugged the OBD2 unit and waited maybe 10 seconds and then plugged it back in and most of the time that solves it. Hope that helps!

[@fairplayer916]

@@AllThingsOverlanding thanks for the advice. I got it to work this way when connecting to my phone, but no luck yet connecting directly to the head unit.

[@Kremboi604]

How do you turn off the reverse camera on screen ?!?

[@AllThingsOverlanding]

Depends on how you have it hooked up I guess? If you wired it into your backup lights like the instructions show, then you just take the vehicle out of reverse and it should cut power to the camera. You might be able to hit the "home" button to get out of it? Or, maybe if it's a constant input (not wired to your reverse lights), you could hook it up to a toggle switch so you could turn it on and off whenever you want.

[@smizx7]

Thank you!

[@AllThingsOverlanding]

No problem! Glad it was helpful!

[@PeterPanoramics]

Mine keeps asking to go into settings and make permanent connection ?

[@AllThingsOverlanding]

Like, every time you connect it?

[@PeterPanoramics]

@@AllThingsOverlanding and I can't find option to make permanent

[@PeterPanoramics]

@@AllThingsOverlanding although it paired , it hasn’t communicated with the torque app to give any readings

[@AllThingsOverlanding]

@@PeterPanoramics Huh, weird. I wonder if there's some sort of support through their Amazon store (I know they sell a lot on there). If it helps, I also found this (with phone, email, and FB messenger support): www.eonon.com/Support.aspx#:~:text=support%40eonon.com%20%2B%201%20256%20598%203849%20OFFICE%20HOURS,EU%20UTC%2B1%201T%2C%20FR%2C%20etc%20%282%3A00AM%20~%2011%3A00AM%29

Thanks gonna give this a try. Mine kept asking for a pin #

[@AllThingsOverlanding]

Glad it was helpful!

[@jsturgillrn]

I tried it and it didn’t work. It shows it but won’t let me connect for some reason

[@AllThingsOverlanding]

@@jsturgillrn Huh. I’ve occasionally had mine not connect when I’m using torque and usually through a combo of unplugging and replugging in the OBD2 reader and resetting the headunit, it’ll just reconnect.

[@jsturgillrn]

I’ll keep trying. Thanks for your help

[@AllThingsOverlanding]

Sorry I couldn't be more help. Good luck!

[@miodrag0078]

What app?

[@AllThingsOverlanding]

I was using the "Torque" app with it.

[@RickDrew]

Not impressed with anything they make. Keeps dropping bluetooth connection and when it does connect, it's another error - not connected to ECU.

[@AllThingsOverlanding]

I mean, they are on the budget side for sure, but I've had a number of their products with no issues. Guess it's kind of a numbers game. I'm not sure how their customer service is, but it may not be the best since they're a Chinese company and that's a factor for sure. I guess my thinking was that since they sell on Amazon, I'm protected to some degree by being able to return stuff via Amazon. Sorry they weren't great for you!

[@mickdrumm]

Did you ever figure out how to get it to connect to the ecu? Dealing with the same problem

[@dokutainmenttiewie3573]

Same Here...No connection to the ecu

[@RickDrew]

@@mickdrumm I had to use different software. The ECU's can use several different protocols, and the app that was included can't handle it.

[@RickDrew]

@@dokutainmenttiewie3573 You need to use a different app. The one they included is terrible.

[@EclipseJay]

Works on my phone but not the Eonon :(

[@AllThingsOverlanding]

That's weird. Maybe try unplugging it and (worst case) unplugging your vehicle's battery for a bit to let it fully reset and then try again?

[@cesarguerrero1211]

Does the OBDii drain the battery if the car is off?

[@AllThingsOverlanding]

It might a bit, but not enough to really cause any problems if you're moving it every 3-5 days. I drive mine at least a couple of times a week and haven't had any problems.
