LAUNCH markets the CRP429 is a professional-level diagnostic scanner for mechanics and auto shops. With the ability to read/clear codes and perform special functions, the LAUNCH CRP429 comes with a mid-range price tag.
But is it worth your consideration? I finally got my hands on one and prepared this LAUNCH CRP429 review.
OVERVIEW of the LAUNCH CRP429
According to LAUNCH CRP429 review, this handheld scan tool offers at least 8 special functions in addition to basic diagnostics. It features an A5 quad-core processor that makes the device quite fast and powerful. Besides powering up in a few seconds, it supports all the diagnostics apps that you would expect in a mid-range scan tool.
The design is pretty standard for scan tools. It’s mostly plastic with a rubberized sleeve for extra protection against impacts. There’s a big touchscreen for viewing diagnostic data as well as navigation.
Under the touchscreen is a keypad with buttons. That’s perhaps the most unnecessary thing on the scanner considering it already has a touchscreen. The good people at LAUNCH had the opportunity to make the screen even bigger and do away with the keypad altogether. Sadly they didn’t!
Included in the LAUNCH CRP429 package is an OBD2 diagnostic cable, a 5V DC charging cable, a user manual and of course the scanner itself; all packed in a padded carrying case.
On paper that’s everything, you need to use this scanner without hitches. Practically, issues of software upgrades and warranty are just as important as the hardware. In that regard, the LAUNCH CRP429 comes with a 12-month warranty and 12 months of free software updates.
Once the 12 months are up you will have to pay for subsequent software updates. Speaking of updates, the CRP429 supports Wi-Fi connectivity. For that reason, updating its software is a breeze, and you will get notifications whenever new updates are available.
LAUNCH CRP429 Detailed Functional Review
An OBD2 scan tool, the LAUNCH CRP429 is compatible with most mainstream vehicle brands. More specifically, it works on most 1996 and newer US-made vehicles, 2000 and newer European-made vehicles, and 2003 and newer Asian-made vehicles.
Coverage includes both gas and diesel-powered cars and light trucks. The only condition is that the car should not be more than 12V. Equally important is the fact that the scanner has auto-VIN that automatically identifies a vehicle.
At its most basic functionality, the LAUNCH CRP429 supports reading and clearing of trouble codes. You can pull generic as well as manufacturer-specific codes. Coverage is for ALL systems, including engine, ABS, SRS, transmission, fuel system, emission system, light system, etc.
In other words, the scanner not only helps you reset the Check Engine Light but also other warning lights. Besides, it provides live sensor data from all the systems (engine, chassis, powertrain, etc.)
You can view the data either as text, analog, digital or waveform graphs. The graphs are particularly important because you can merge and compare the information for easy analysis.
In addition to reading and erasing codes, the LAUNCH CRP429 offers several reset functions. For starters, by clearing OBD2 codes it allows you to reset engine, ABS, SRS, transmission, fuel and emission systems to name a few.
Besides the above, the scanner supports resetting of oil service, EPB, SAS and BMS. Oil service reset is usually necessary mostly after changing oil or maintaining the oil system.
Oil service reset is usually necessary mostly after changing oil or maintaining the oil system.
EPB (Electronic Parking Brake), on its part, needs resetting after repairs in the EPB system or if a brake pad has been replaced. The same goes for BMS (Battery Maintenance System) and SAS (Steering Angle Sensor).
According to LAUNCH CRP429 review, it also supports DPF regeneration, SAS calibration, and ABS bidirectional tests. DPF (Diesel Particulate Filter) regeneration basically involves emptying the filter that captures and stores exhaust soot to minimize pollution.
SAS calibration refers to adjusting the steering angle. On their part, ABS (Anti-Lock Braking System) bidirectional tests make it possible to command the ABS to perform actions remotely (using a scan tool).
Coding and Programming
Finally, the LAUNCH CRP429 review show that it can perform injector coding, IMMO and battery re-matching. Injector coding is the process of writing new code to a car’s ECU after replacing an injector component. That leads to accurate communication and proper injection control.
IMMO makes it possible to clear the information held in a lost car key. By doing so it protects your car against theft. The only unfortunate part is that the LAUNCH CRP429 cannot program new keys. On the upside, it does support resetting and registration of a new battery.L

LAUNCH CRP429C are basically similar in functionality. They offer the same basic and advanced diagnostic functions including full-system diagnostics, reset functions, etc.
The difference between these Launch CRP429 vs CRP429c in connectivity and vehicle compatibility. While the LAUNCH CRP429 review has Wi-Fi capabilities, the CRP429C doesn’t. Also, the latter supports both OBD1 and OBD2 diagnostics, contrary to the LAUNCH CRP429 review which only works on OBD2 vehicles.
The LAUNCH CRP423 offers significantly less than the first two scanners. It neither supports their range of reset functions, special functions nor coding and programming functions. That said, it can do full-system scans.
Additionally, the CRP423 covers both OBD1 and OBD2 vehicles. The benefit of buying it over the other two is that it supports several tests, particularly on-board monitor tests, I/M readiness tests, O2 sensor tests, and EVAP system tests.
- Can I use the LAUNCH CRP429 on a truck?
The scanner only works on 12V vehicles, not heavy trucks
- Does it work on diesel cars?
Yes, it works on 12V diesel cars and light trucks
- How can I update the software?
Make sure you have a reliable Wi-Fi connection. On your LAUNCH CRP429, go to Settings >> Version >> Detect the System Version. You will get a step-by-step guide for updating.
- My LAUNCH CRP429 halts mid-operation, what’s the problem?
It may be caused by a loose connection at the OBD2 port. Turn off the scanner and connect it to the car firmly
- Scanner fails to detect my car automatically, what should I do?
First, ensure that the scanner is tightly connected to the OBD2 port. Then check that the “Automatic Detection on Connect” is switched ON. If it fails choose your car manually from the database.Check Price at Amazon
