Along with the live data and freeze frame features, no errors you can’t identify.


As an all-range OBD II scanner, Launch CRP123 can actually work on most US, European, and Asian vehicle makes, you just name it. The compatibility is basically subject to the OBDII support of your vehicle but it works on the wider range when it comes to the big 4 data reading. With higher compatibility, Launch CRP123 should work on your vehicle as long as you can find the 16-pin DTC port on your dashboard.

It has the DTC library that supplies you with pivotal information about the definitions and descriptions of the codes. Not only the generic codes, but you can also get the meaning of manufacturer-specific codes appearing on the scanner screen. You can visit Launch’s official website to confirm the compatibility.  

Live data

Launch CRP123 features a legit live data stream experience. With a larger LCD color screen, Launch CRP123 supports the 4 in 1 live data. It means that you can view the live data of four major systems in one graph including the engine, ABS, SRS and transmission. In the data stream mode, you’d have four different colors in the graph which each represent the readiness of each system.

This way, you can straightforwardly elaborate and analyze the data parameters as it’s diagnosing your vehicle. You can figure out the symptom-specific parameters or triggering points of the DTCs and help you focus on the actual problems in your vehicle.

Read VIN

Launch CRP123 comes with VIN reading capability since it supports the 10 modes including mode 09 for requesting vehicle information. When you start diagnosing one vehicle it could take a long time especially if you want to go comprehensively. As Launch CRP123 can read the VIN, it would help you with the recalibration of the corresponding components.

This way, you can save time and energy to do a comprehensive diagnosis on a vehicle. Even if you have multiple vehicles to scan, you can streamline the process and make it more manageable. You can eliminate hassles on these particular diagnosis tasks.

Onboard Monitor test

As you might have known, when you need to get accurate emission-related DTCs that are confirmed, you’d need an onboard monitoring test. The OBD system would confirm any malfunction on the corresponding systems but not all scanners can retrieve the codes. Launch CRP123 has the capability of an onboard monitor test, so you can diagnose and analyze emission-related sensors or systems further.

This function is crucial if you want to accurately recognize problems that affect your engine performance and efficiency. This is actually the corresponding request of mode 06 that covers retrieval of the on-board monitoring test results on EVAP systems, or specific monitored systems.

Freeze Frame

As it also supports mode 02, Launch CRP123 can also request freeze frame information. Despite viewing the live data when diagnosing, the scanner is also capable of freezing the frame data at the moment it’s triggered.

Launch CRP123 can also record the data history of diagnostic sessions so you can always refer back to the before-after data for maintenance, calibration, or repairs. This way, any DIYer or mechanic can keep tracking of the vehicle’s records for further diagnosis and maintenance.

I/M Readiness

Want to know whether or not your vehicle would pass the annual emission test? You can check the I/M readiness with the Smog test. Launch CRP123 supports mode 03, mode 04, mode 067, and mode 0A which provides you with everything related to the emission performance. They’re all there in Launch CRP123 and you don’t need to buy separate tools for the test.

Mode 03 enables you to retrieve emission-related trouble codes while mode 04 allows you to clear or reset those emission codes. With the DTCs on your hands, you can ensure the problems are fixed and your vehicle passes the test.

Lifetime Software Update

As previously mentioned, Launch CRP123 comes with a lifetime free update. Despite the firmware, the updates from the manufacturer also cover the DTC library. This way, you can extend the Launch CRP123 use-life for more years and for diagnosing newer vehicles as well.

You can get the most of your Launch CRP123 scanner and extend your user experience longer.  The updates are available online and you can also obtain tech support from the manufacturer.

Advance features Launch crp123 Review

ABS Systems

If you’re riding a newer car with an anti-lock braking system(ABS), then you’d need a scanner that can cater to this function as well. The performance of your ABS systems is critical to your safety riding experience since it controls the braking force and prevents it from locking which could be hazardous.

Launch CRP123 is capable of scanning your ABS system and providing you with information on whether there are problems in the component. With the scanner, you can practically check your ABS anytime you need and ensure that it works fine for long trips or daily trips.

Transmission System

Launch CRP123 can reliably read the codes of your transmission system and reveal the problems on different components. Sometimes it’s not your engine but the stalling transmission that decreases the performance of your car. On the other hand, you might have experienced rough transitions between gears. With the capability of transmission-code reading, you can potentially eliminate performance problems coming from your transmission system.

You can use Launch CRP123 to scan both manual or automatic transmission and bring your DTCs.  The DTC library would tell you the definition of the corresponding codes so you can either repair or replace the components. Either way, you can ensure the best performance of your vehicle with the scanner on your hand.

Supplemental Restraint System(SRS)

SRS is a pivotal part of the safety system in your vehicle that covers the airbag and seatbelt. While it’s crucial for safe riding, it’s hard to know whether they’re working. Launch CRP123 is able to read the DTCs of your SRS so you can ensure the actual condition of the system.

The properly functioning SRS would expand the air passenger in the first impact of the collision. Even though it’s considered supplemental, this restraint system is the critical safety feature that protects you from being fatally impacted by a possible collision on the road.

4 in 1 Live Data Graphing

The big size LCD screen provides Launch CRP123 with more flexibility in displaying various data. The ultimate viewing feature of the scanner is, of course, the 4 in1 live data graphing. The large screen makes displaying four different graphs in one layout possible. Launch CRP123  allows you to stream live data of engine, ABS, SRS, and transmission on one screen.

Instead of changing the default system interchangeably, you can view the four graphs in different colors. You can easily notice the triggering points of these systems and won’t miss one because they’re all there altogether. There’s no necessity to do four-time diagnosis sessions just to view the live data of the four systems.
