Another great feature of the CRP129E and CRP129X’s designs is that they are powered by a 400 mAh Lithium-Ion battery. The battery is rechargeable and long-lasting, and it comes with the scanner. Being free from a power cord gives you a lot more flexibility as you perform your diagnostics.

Basic Features and Functions

The Launch CRP129 diagnoses four car-systems (Engine, AT, ABS, and SRS) and has three reset functions (oil, EPB, and SAS). This covers all your basic needs as far as checking major systems for problems and turning off pesky warning lights. 

One of the most common uses for the Launch CRP129 is to do smog tests and verify your vehicle meets your state’s emission standards. It can check your air and fuel ratio, fuel injection, and engine ignition, as well as running carbon canister and oxygen sensor tests. You can use this data to maximize your car’s gas mileage, so it saves you money along with helping the environment.

The Launch CRP129 is also handy for resetting your systems after making repairs or replacing components. It’ll reset your oil system so you can trust the accuracy of your check oil light again. You can also use the Launch CRP129 to release an electronic parking brake or calibrate your steering column angle.

Again, the Launch CRP129X does all of that and then some. It can reset your TPMS and throttle position along with the standard systems covered by the Launch CRP129. The auto-VIN scan feature is helpful, too, letting you quickly obtain your vehicle’s information.

The Launch CRP129E takes it further still. If you want to really know what’s going on inside your car’s engine, you’ll love the Launch CRP129E. It can tell you why your airbag warning or check engine light is on and disable them once you’ve fixed the problem. It also diagnoses your OPDS and EVPS systems, something the Launch CRP129 and Launch CRP129X can’t do.

Additional Features and Functions

Both the Launch CRP129 and the Launch CRP129E read and clear DTC codes. The Launch CRP129E also lets you store DTC data and read current pending codes and permanent codes. All three models include an onboard DTC library, saving you time when it comes to interpreting the error data.

For monitoring your battery, the Launch CRP129 and Launch CRP129X have a voltage test. For real-time monitoring of your battery’s operation, you’ll want the Launch CRP129E. You can see this data graphed, as well, which helps track your battery’s performance over time.

All of the diagnostic tests performed by the Launch CRP129E can be recorded. This might be the most impressive feature of this powerful scanner. You can play the data back, store it, print it, or send it to yourself through email.

The Launch CRP129X also has full recording and playback of data. You can save, share, and print the overall inspection report, a helpful tool if you want to show your mechanic exactly what’s wrong with your car.

Supported Protocols

The Launch CRP129, Launch CRP129E and Launch CRP129X all support all five signal protocols of the OBDII test. These protocols include:

  • SAE J1850 PWM: The standard protocol of the Ford Motor Company, using pulse-width modulation.
  • SAE J1850 VPW: The standard protocol of General Motors, which uses a variable pulse width.
  • ISO 9141-2: This protocol is typically found in European and Asian vehicles. It uses an asynchronous serial data rate, with communication on one bidirectional line.
  • ISO 14230: This is the keyword protocol 2000. It has a high signal voltage, over 12-volts.
  • ISO 15765 CAN: This protocol is widely used outside the automotive industry and was developed for industrial controls. It has a relatively low signal voltage level compared to the other protocols.

OBDII Testing Modes

All the models here support all ten modes of the OBDII test. Where the Launch CRP129E really out-paces the Launch CRP129 and CRP129X is in its data management. The Launch CRP129 gives you a dynamic graphic display of the data. The Launch CRP129E lets you view live data in both graphic and text formats. It also gives you the extended manufacturer’s OBDII data you won’t get from the standard CRP129.

Supported Vehicle Makes

The Launch CRP129 supports most vehicles made after 2006, covering 40 different companies, including popular brands like Ford, GM, Mazda, Honda, Kia, Nissan, and Audi. The main exceptions are vehicles with diesel engines, and it doesn’t support diesel trucks.

The vehicle support on the Launch CRP129X is slightly expanded. It functions perfectly on 57 vehicle brands and can work on older vehicles that the Launch CRP129 doesn’t support. This generally includes any North American cars made after 1996.

The Launch CRP129E supports even more models than the Launch CRP129X, including luxury and sports brands like Bugatti, Bentley, and Rolls Royce. Owners of larger vehicles will also want to get the Launch CRP129E, supporting some light-duty trucks. Many hybrid cars are also supported by the Launch CRP129E, but not the Launch CRP129.

Software and Updates

All three versions of the Launch CRP129 come with free online upgrades for life. You’ll never need to worry about any of these models becoming outdated. These updates are also multi-lingual, with nine language options to choose from.

The software of the Launch CRP129E is more sophisticated than what you’ll find on the Launch CRP129 or CRP129X. It uses an Android-based operating system so that Android users will feel right at home. Because it has 1GB RAM, you’re able to store many diagnostic results at once.

Improved software also gives the CRP129E the option of the feedback feature. You can form a database to store your sensor data. The Launch CRP129E also offers more control over your graphs, with the option to separate, merge, and overlay them.
