LAUNCH CR123i vs. CRP123X vs. CRP123E: Detailed Comparison

Key Things in Common

At first glance, these three OBDII scan tools look very similar. The LAUNCH CR123i, CRP123X, and Launch CRP123E are all hand-held OBD2 scan tools with a 5” touchscreen interface surrounded by a rugged, rubberized housing. 

Besides, these LAUNCH scan tools all use an Android 7.0 operating system. This ensures the accuracy and speed of diagnoses and provides an intuitive, easy to navigate interface. You can use these OBD2 code readers for a while between charges, too, since all include a 6100mAh battery. 

Functionally, these are three powerful OBDII diagnostic tools. Firstly, all of them include a 4-system diagnosis as well as battery monitoring. You’ll also be able to send that diagnostic information easily to another device, thanks to their onboard Wi-Fi. 

Key Differences

Design and Specifications

The main design difference between these OBD2 diagnostic tools is how you navigate. With the LAUNCH CRP123E OBD2 scan tool, the touchscreen is the only navigation option. On the other hand, both the CR123i and CRP123X have buttons and a touchscreen. This design makes it easier to navigate mid-repair when your hands are in grease and grime. 

Overall Features and Functions

The functions of the LAUNCH CR123i start with all 10 modes of OBD2. With this LAUNCH code reader, you can see trouble codes, live data, and freeze frame data, along with conducting emissions tests and turning off the check engine light. Additionally, it diagnoses more than just the engine, with a 4-system diagnosis that includes the transmission, ABS, and SRS. This data can be graphed, recorded, and sent to e-mail for printing. 

You’ll get similar basic functionality from the LAUNCH CRP123X. Like the CR123i, it automatically generates a Diagnostic Report that lets you evaluate your vehicle’s health at a glance. The auto-VIN function is helpful, too, sparing you from the need to enter your vehicle’s information manually. 

Finally, the CRP123E OBD2 scanner takes its 4-system diagnosis a step further. It can graph up to 4 parameters on-screen to compare, analyze, record, and playback data.

Extra Features/Functions

One great thing about the CR123i is that it’s more than just an OBD2 code reader. Along with reading trouble codes, it reads live data from systems like the transmission and anti-lock brakes. This great feature allows you to make more informed repairs and identify what’s triggering dash warning lights. 

Similarly, the CRP123X will read both DTCs and live data from the engine, ABS, and transmission. We also appreciate that this OBD2 diagnostic scanner has a built-in library for looking up code definitions from all 4 supported systems. Because of that, you won’t have to waste time finding the meaning of codes on your own. 

While all 3 of these LAUNCH scanners have real-time battery monitoring, we found this function most comprehensive on the LAUNCH CRP123E. The LAUNCH CR123i and CRP123X can graph the battery voltage, so you know if it’s operating in the normal range. With its fast processor, the CRP123E provides truly instantaneous readings, letting you identify the most commonly overlooked battery issues. 

Supported Protocols

The LAUNCH CR123i supports all 5 standard protocols of the OBD2 system, making it a comprehensive OBDII scan tool for vehicles made and sold in the United States. For vehicles made in Europe, the CRP123X is a better choice, as it supports both OBD2 and EOBD protocols.

Ultimately, the CRP123E has the broadest protocol support. Along with OBD2 and EOBD, it supports JOBD (for vehicles made in Japan) and OBD1 (for vehicles made before 1996).

Supported Vehicle Makes

Similar to the supported protocols, the CRP123E has the widest vehicle coverage. Its list of supported vehicles covers more than 10,000 makes and models from all over the world. 

That said, the vehicle coverage on the LAUNCH CR123i and CRP123X are very broad, as well. Both support more than 57 vehicle brands and will perform basic diagnostics on any OBD2-compatible vehicle. 

Keep in mind that compatibility may vary for non-OBD2 systems, such as diagnosing the transmission, ABS, and SRS. If you want to verify whether they’ll work on your vehicle, you can e-mail your VIN information to [email protected] to determine the specific function compatibility. 

Software and Updates

All 3 of these devices use an Android 7.0 operating system, so they all perform similarly well in terms of speed and accuracy. The main difference between them from a software perspective is the number of supported languages. 

Surprisingly, the LAUNCH CRP123E supports the least, with 9 language options. The CR123i and CRP123E support 10, adding an option to see data in Japanese. 

For updates, all 3 of these LAUNCH OBD2 scanners have built-in Wi-Fi so that you can update straight through the device. Best of all, these updates are free for life for all 3 scan tools. The CRP123X and CRP123E have a convenient one-click update option, too.

Recommendation

Generally, we’d recommend all 3 of these tools to beginners and intermediate home mechanics. Their comprehensive diagnostic power will help determine the cause of vehicle issues. However, they lack the repair and service functions advanced that DIYers (and professionals) may need.

If we have to choose, the LAUNCH CRP123X will be our top pick.

FAQs

How do you recharge the battery in the CR123i, CRP123X, or CRP123E?

💡 All three OBDII scanners come with a cable that you can plug into the outlet for recharging. Alternatively, you can charge them through the vehicle’s battery by connecting to the vehicle’s DLC. 

Do I need to be in Wi-Fi range to use these LAUNCH diagnostic scanners?

💡 No. You will need to have an available connection to update the device or send the Diagnostic Report via e-mail. For conducting diagnostics, though, no Wi-Fi is required. 

Can the LAUNCH CR123i, CRP123X, or CRP123E turn off the check engine light and other dash warning lights?

💡 Yes, these OBD2 diagnostic scanners support clearing codes from the engine, ABS, and SRS systems, which will deactivate dash warning lights. However, if the issue that triggered the error codes is still there, the light will turn back on. If your dash lights don’t turn off after clearing codes, review the codes triggered to identify the underlying issue. Once you complete repairing, you’ll be able to turn off the light. 

Can the LAUNCH CRP123X bleed the brakes for ABS?

💡 Unfortunately, no. These LAUNCH OBDII scanners all support ABS diagnostics, but they don’t have the bi-directional control required to perform repair functions like brake bleeding. 

What vehicle model years are supported by these LAUNCH code readers?

💡 The CR123i and CRP123X support most vehicles made after 1996. This includes the newest 2019 and 2020 model years. For vehicles older than 1996, the CRP123E is your top choice. It supports both OBD1 and OBD2 protocols, allowing it to work on any US vehicle regardless of its model year. 

Final Thoughts

Functionally, the LAUNCH CR123i vs CRP123X vs. CRP123E are very similar. The more critical factor for most will be the compatibility with your vehicle and how you want to navigate the tool. We hope the side-by-side break-down here has helped you find the ideal LAUNCH OBDII scanner for you!
