It will always show up in the worst place at the worst time. Like the end of a long road. That little yellow icon on the dashboard means one thing: something is wrong under your hood. Or with your gas tank. Or with one of a hundred other vehicle sensors. There are two things you can do to find out the problem: go to your dealership and do an hour’s work to find out, or get your own engine check scanner and find out the problem yourself. We choose the latter, especially if you’re still on the road.
An OBDII scanner — named for the On-Board Diagnostic II protocol used in every vehicle in the US since 1996 — taps into the secretive computer network in your Jeep. Every bit of information, from air intake temperature to water pump action, is sent over this network for the ECU to figure out and adjust as needed.
The right scanner can read all of this data along with standardized diagnostic trouble codes. The codes that trigger your check engine light. The best scanners can go beyond standardized codes to read OEM-specific codes and give you even more information. Of course, that costs more money. That’s why we asked the Obd2tool.com to tell us which OBDII scanners are worth investing in. We’ve highlighted some of your choices below.
1. Foxwell NT530

The NT530 is a dual-direction scanner that can communicate with a wide range of vehicle sensors and modules. Foxwell says that it offers OEM levels of connectivity and diagnosis to help you narrow down exactly what the problem with your Jeep is and get it fixed. While the NT530 can support basic functions on all vehicles, it comes with one software module that is manufacturer-specific. You can pick which module, so for use on your Jeep you’d pick the Chrysler software. That gives you enhanced access to the modules and systems of your Jeep. Foxwell offers lifetime updates for no extra charge as well, making sure that if you upgrade to a newer car, then you can still handle all of your diagnostic needs.
2. Autel AutoLink AL329
Communication Device Rectangle Gadget Measuring instrument Electronic device
Autel makes professional-level diagnostic computer systems. Thank you to Skiteach, a Jeepforum.com community member for this suggestion. Watch any YouTube mechanic show, and this is probably the system you’ll see in use. While the company makes very high-end systems, it also makes some that are much more accessible for the average DIY mechanic. That includes stand-alone tools, handy if you don’t want to deal with Bluetooth or wireless phone connections and apps, and instead just want to plug and know. Its MaxiSys models can do nearly anything the factory computer can do, even reprogram advanced driver assistance systems, but that comes at a cost. For a more DIY-friendly option, we like the AL329. It has a color screen with an easy-to-read display. The 329 can retrieve generic and manufacturer-specific codes, see emissions status, and view freeze-frame data. It doesn’t have all of the bells and whistles, but it gets the basics done to help you get your Jeep running right at a very affordable price.

4. New Arrival AEV ProCal Module
Users will also love the ProCal Module for the other options it provides. Their vehicle’s factory Tire Pressure Monitoring System can now be recalibrated to allow for lower street pressures without triggering the annoying dash light. Further, the ProCal Module makes it possible to activate daytime running lamps, one-touch turn signal options and temporarily increase engine idle speed for winching.
The ProCal Module is equipped with a series of easy-to-use dip switches. By reading the simple code card included with the Module, any user can quickly dial in a code for the desired recalibration. From there they simply plug the Module into their vehicle’s OBD port and wait for the horn to honk. The whole process can be completed in mere minutes and it’s just as easy to reverse.
Module Functions:
Large tire recalibration (Restores the vehicle’s speedometer/odometer accuracy following the installation of larger-than-stock tires)
Axle gear ratio recalibration (Resets automatic transmission shift points to maximize the benefits of an axle gear ratio change)
Tire Pressure Monitoring System recalibration
Daytime running lamp activation/deactivation, and lamp location selection
One-touch turn signal activation/deactivation
Engine idle speed options (Improves winch performance and battery charging capabilities by temporarily increasing engine idle RPM)
Steering wheel centering (Provides for spot-on steering alignment)
