I have a 2018 JLU, 2013 Honda Odyssey and Just picked up a 2013 jk with every light on. I’d like to troubleshoot the abs, airbag and traction control to specific issues and clean the oil valves / cam phasers too.

I see JScan on here but not sure if it’s only for tuning? I’d love to get rid of the knock in my 2018. I’ll pay more to cry once sort of thing.

Appreciate the forum

No brainer. This is the best bang for your buck:

OBDLink MX+ OBD2 Bluetooth... https://www.amazon.com/dp/B07JFRFJG6

For JScan you also need a secure gateway bypass from ECRI. Forum member sells a 3D printed mount for the same. And SGW extension cables from ZAuto would also be a wise investment.

@Rhinebeck01 has many threads with details on this setup.

Thank you…. I have no idea what any of that means lol.

So just go with the Bluetooth one on the 1st link and extended cables?

Just as another option to bluetooth, I've had a Foxwell NT510 for years that is bidirectional and can have OEM addons.

Jscan will read and clear codes on your Jeeps. If you go with Autel, you will an MX808 or better. You will also need some sort of SWG by pass. Search the forum, lots of info on that.

Just to set the record straight, JScan is not a tuner. It is an excellent product for getting error codes and also for changing settings such as tire size and gear ratios and much more. It cannot add or delete files nor can it 'flash' ECM's or TCM's.

Chrysler vehicles have a secure gateway that prevents non-dealers from accessing OBDII. The ERCI bypass is just a small plastic bypass module. You take the SGW connectors out of the factory harness and plug them into the ERCI. Simple process.

The extension cables just make it easier to repeatedly switch between bypassed and factory configurations. (The factory location is a bear to reach.)

Your Odyssey and JK will “just work” with the Bluetooth device I linked above.

No.

To use *any* OBDII device (except for Chrysler’s WiTech scanner, which only dealerships have) you need to use the ECRI bypass.

The extension wires are just to make reverting to factory setup quick and easy.

So regardless of what scanner/programmer you buy, you need those two items.

The MX+ works with any vehicle that has an OBDII port (everything from 1996 onwards) and comes with OEM plugins. In other words, buy once cry once. The less expensive devices have in app purchases to unlock OEM functionality. Since you have three vehicles to work on the MX+ is your best bet.

JScan is a programmer. It does what the MX+ included app does, but it also lets you modify factory settings like tire size and gear ratio. Do a forum search to see what else it can do or visit JSCAN.net and read the doc.

You don’t need the bypass for the JK… JScan and a BT OBDII reader will do it all…. You JK issue is speed sensor…. Need a reader to tell you which one :like:

As many have already said short of the Mopar factory tool that has the ability to access the SWG there are no tools on the market that you can simply plug into the OBD2 port to access all systems.

Consider a professional scan tool such as an Xtool D9 or Maxisys which not only can you use on your Jeep but just about every other in production vehicle. You can get both of these tools with the optional Jeep SWG cables that allow the tool to plug in-line totally bypassing the SWG and giving you full access to the systems.

These tools are also bi-directional so not only can the read codes but they can actually do activation testing of specific modules. Granted these tools are geared more for the professional mechanic.

They are also more expensive then a jscan or BT reader but they do one heck of alot more and you can use them for just about anything you might own now and in the future. If you just want to read codes and don't plan on any serious work or testing on your jeep get the jscan, for the average jeep owner its the best bang for the buck and easiest to use.

FYI - the MX+ I linked is bidirectional *with the right app*. For $140, it’s a phenomenal tool.
