LAUNCH X431 CRP429C Overview

The Launch X431 CRP429C is a fairly new scan tool. It only became available for purchase in the last half of 2018. And so far it has been received with a lot of enthusiasm from car owners, dealers, and mechanics.

But is this OBD1/OBD2 scanner worth your hard earned buck? Read on and find that out. You may want to know that we prepared this review after a hands-on experience with the device.

First things first, when you purchase the Launch CRP429C scan tool it will be shipped complete with all the accessories. That includes the CRP429C scanner, an OBD2 diagnostic cable, one charging cable, a user manual, and a carrying case.

The carrying case is a nice little bag that is completely black save for the large LAUNCH’ imprint that’s red. It makes a great addition to the package especially for those who may want to walk around with the device. That is unavoidable if you are a car dealer or mechanic who goes far and wide either buying/selling or repairing vehicles.

The packaging may be nice but it’s probably the least important thing in an OBD scanner. Performance and functionality are more essential. So how does the Launch CRP429C automotive diagnostic tool perform when it comes down to the real business? Well, let’s find that out. We will start by comparing it with two other Launch scanners.

Launch CRP429C vs. Launch CRP429

The CRP429 is, in fact, the immediate predecessor of the CRP429C. As such, you would be right to assume that the latter is superior because it is.

Both devices support full OBD2 mode. That means in addition to pulling and clearing codes you can use them to reset the Check Engine Light and any other warning lights.

However, the Launch X431 CRP429C has more special functions. It supports ABS bleeding, throttle position matching (TPM), gear learning, DPF regeneration and TPMS reset. You won’t find those in its predecessor.

But they do have a few advanced functions in common. For example, they both support oil reset, EPB reset, SAS reset, ABS tests, BMS reset, IMMO and injector coding.

In terms of vehicle compatibility, the CRP429C covers both OBD1 and OBD2 cars. You will need a cable for OBD1 diagnostics though (not provided). The same cannot be said for the CRP429 which only supports OBD2 diagnostics.

Long story short, if you want more advanced features and a wider vehicle coverage then the Launch X431 CRP429C is a better buy. In fact, it’s more affordable than its predecessor.

The Launch Creader VIII is a multifunctional obd2 scanner for the most important car systems, including ENG/AT/ABS/SRS/ 4 basic systems and reset functions

If you find that the CRP429C has more functions than you need you may consider going for the Creader VIII. The latter supports all OBD2 modes and just a handful of special functions.

They include oil service reset, EPB reset and SAS reset. It doesn’t have the wide range of advanced functions that you will get on the CRP429C. Plus it only covers OBD2 cars. That explains why it’s cheaper.

LAUNCH X431 CRP429C Detailed Review

You may have noticed that the Launch X431 CRP429C trumps both devices that we’ve compared it with above. But that’s not all there is to this scanner. In case you are deliberating on buying it here are a few features that may give you the green light.

Offer Full-OBD2 Functions

As soon as you plug the Launch X431 CRP429C it will automatically detect your car. It will show you the make, model, year and (in some cases) mileage of the vehicle. After that, it will lead you to diagnostics where you can choose the systems to scan.

Note that the auto-detect feature doesn’t work on every single vehicle. For example, there are reported auto-detection issues with the 2006 Nissan Teana and 2002 Mazda B2300 pickup. Just in case it fails on you don’t worry, you can choose your car make and model manually from the built-in database.

Once the LaunchX431  CRP429C scan tool has identified your car it will start doing an automatic scan while displaying the battery monitor at the top. Battery monitoring shows the actual voltage of your car battery. Be careful not to do many tests with a low car battery as it may give faulty diagnostic data.

Speaking of diagnostic data, you can read and erase codes from the car’s main systems. They include ECU, ABS, SRS, transmission, powertrain, body, chassis etc.by clearing all the codes of a particular system you will be able to reset that system’s warning light.

  • For example, after clearing ECU codes the Check Engine Light will reset. Alongside the DTCs, this device also gives part numbers of faulty components just in case you need to buy replacements. It also runs I/M readiness and O2 sensor tests.

One of the handiest features of the Launch X431 CRP429C scanner is its built-in database with DTC definitions. It also features a Wi-Fi module. You can connect this scan tool to the internet and do a DTC lookup or find replacement parts.

The other important feature is the 8GB built-in memory. It saves each scan session automatically so that you have that info for future reference.

Perform 11 Special Reset Functions

In addition to full OBD2 diagnostics, the Launch X431 CRP429C also supports 11 other advanced functions. They are ABS bleeding, oil service reset, gear learning, injector coding, BMS, TPS, IMMO, SAS reset, DPF regeneration, EPB, and TPMS reset.

Solid Construction

Contrary to most other launch tools, the connection port of the Launch CRP429C scanner is at the bottom. It’s actually the first Launch scanner with the design. But that shouldn’t be a buzz kill even if you are not used to such a layout.

Navigation combines both buttons and a touchscreen for more convenience. There’s a HOME button at the bottom left that can return you to the main menu with just one click. The top left has an Auto-VIN button for detecting cars automatically. On the immediate right of the Auto-VIN button is an I/M button for checking emissions instantly.

The other handy button is the Screenshot button that allows you to do just that – take a screenshot of whatever is appearing on the scanner’s screen at any given time. Whether its DTCs live data or vehicle info, you may need the record for future reference.

Once you connect the scanner it will start detecting your car and display the vehicle info using Automatic VIN. Pressing the OK tab will then display the vehicle health after about 10 minutes (of generating the report). The report basically consists of trouble codes with a brief description of each.

Once you’ve saved and/or analyzed the diagnostic report you can go back to the home screen. There you will find 6 icons, each with its set of functions.

The first is the ‘Diagnose’ icon which basically generates a diagnostic report. Use it when the scanner fails to do so automatically after connecting it to a car. Secondly, there’s the ‘OBDII’ icon for checking specific OBD2 systems. For example, if you want to check ABS only you select this icon and then proceed to ABS.

The third is the ‘Reset’ icon which resets the Check Engine Light and other warning lights.

Fourthly there is the ‘Upgrade’ icon which does exactly that – updates the scanner’s software. The ‘Data’ icon is where all your reports, screenshots, and diagnostic files are stored.

Finally, there is the ‘Settings’ icon where you will find all the devices settings. You can change such things as location and units of measurement. This is also where you will find such information as the type of scanner, its software version and so much more.

Live Data and Graphs

Besides DTCs, the Launch X431 CRP429C feeds a user with a ton of data in text and graph formats. You can do a data stream, view freeze frame data and run on-board monitor tests. It gives diagnostic reports that are printable and also allows you to record diagnostic reports. You can playback the data at a later time.

The other likable thing is graphing of data and comparing of graphs. Additionally, the scanner keeps historical codes. If you’re a mechanic and a customer claims the code wasn’t there before you can pull out the history and show them the code and when it first appeared.

Extensive Compatibility

Primarily an OBD2 scanner, the Launch X431 CRP429C is a full system scan. It works on all mainstream OBD2 vehicles. Launch Tech claim that it covers a total of 46 car brands including Ford, GM, VW, BMW, Toyota, Jaguar, Audi, Hyundai, Honda and many more.

The scan tool can also diagnose OBD1 cars. But you will need to buy an OBD1 cable because it doesn’t come with the package. That’s not a big problem for OBD2 car owners, but compatibility issues might prove to inconvenience.

For example, there are reported failures on some Asia and EU made cars like 2006 Nissan Teana, Nissan Altima and 2002 Mazda B2300 pickup.

Shortcomings of LAUNCH X431 CRP429C

The Launch CRP429C automotive diagnostic tool is undoubtedly a great tool. But it’s not short of flaws. Here are the main highlights:

  • Compatibility issues with some EU and Asian-made cars
  • Doesn’t support such functions as relearn, coding and programming that professional mechanics frequently need
  • Has a cheap feel because it’s made of plastic. The rubber surrounding the case makes it look better though.

Who Is It For?

This tool is ideal for experienced enthusiasts and mechanics. The combination of full OBD2 functions and 11 special functions make it ideal for detecting faults in a variety of on-board systems. Enthusiasts are particularly likely to love the wide range of advanced diagnostic functions.
