System diagnostics:
This function is specifically designed to diagnose the electronic control systems of a specific vehicle model.
All basic functions support full vehicle system diagnosis in all pre-installed vehicle diagnostic software.
Notes:
-
You can access the basic functionality to full functionality by ordering the extension from the Mall -> Full function section.
-
If the test vehicle is not covered by the pre-installed software, order the necessary software from the Mall -> Software section.
Smart diagnostics (Automatic detection):
This feature allows you to quickly access the vehicle's electronic control systems by decoding the VIN (Vehicle Identification Number) without having to manually navigate through the menu step by step. After establishing the connection, turn the ignition key on and the system will enter automatic recognition mode.
Notes:
Once the system successfully obtains the vehicle's VIN, it will proceed to scan the vehicle's systems. Once the scan is complete, a diagnostic report will be automatically generated and sent to your email inbox (if email is linked).
Manual diagnostics:
If the device cannot obtain VIN information, you can also perform vehicle diagnostics manually. In this mode, you should use the menu-based command and follow the on-screen instructions to proceed.
Notes:
-
Before diagnosing, make sure that the diagnostic program for the vehicle model in question is installed on your device.
-
The diagnostics menu may vary depending on the make, model and year of the vehicle.
Maximize your efficiency and profitability with the CRP129E PLUS diagnostic tool
SRS System: The Seat Belt Restraint System (SRS) consists of crash sensors, a control unit and airbags. This diagnostic tool is able to check all electrical parameters to assess the health of the system.
Brake system: If the brake pedal feels soft or you notice an unusual smell or sound, proper brake system function is critical for safe driving and control.
Exhaust system: The system's performance can be affected by the age of the vehicle or poor quality fuel. A good exhaust system will significantly reduce harmful emissions and protect you from fines.
Fuel system: If your car won't start or the check engine light is on, check your fuel system regularly to keep your car performing well and emissions low.
Wiper system: If the wipers crackle or leave streaks, visibility can be reduced and pose a risk of accident if the car is not checked regularly.
Lighting system: If the turn signals are unstable or the lights dim quickly, there may be a fault in the system.
Provide complete OBDII diagnostics:
This option provides a quick way to check diagnostic trouble codes (DTCs), locate the cause of the engine malfunction indicator (MIL) illumination, check the status of monitoring systems prior to an emissions inspection, verify repairs made, and perform other emissions-related services.

Vehicle coverage:
This tool is specifically designed to work with all OBD II compliant vehicles, including CAN (Controller Area Network). The United States EPA (Environmental Protection Agency) requires that all passenger cars and light trucks sold since 1996 be OBD II compliant. This applies to all American, Asian and European vehicles.
A small number of 1994 and 1995 gasoline-powered models are also OBD II compliant. To check if your 1994 or 1995 vehicle is OBD II compliant, check the following:
-
Vehicle Emissions Control Information (VECI) label. It is most often located under the hood or near the radiator. If the vehicle is OBD II compliant, the label will say “OBD II Certified.”
-
Government regulations require that all OBD II compliant vehicles have a “common” 16-pin Data Link Connector (DLC).
Note: Some 1994 and 1995 vehicles may have a 16-pin connector but are not OBD II compliant. Only vehicles that have the “OBD II Certified” label on their emissions label are OBD II compliant.
11 languages available:
Supports over 11 menu languages. On the home screen, tap Settings > System > Language & input > Languages, and you can switch from English to languages such as French, Spanish, German, Korean, Japanese, Portuguese, Italian, Traditional Chinese, Russian, Polish, etc.
Model functions:
This function allows you to order other vehicle diagnostic software that is not pre-installed on the device and expands the pre-installed basic functional software with full functionality.
There are two modules available:
-
