Features
Functional All Modes of OBDII Diagnostics
This tool works on MOST OBDII/CAN protocol compliant 1996 US-Based, 2000 EU-Based and Asian cars. It can check all engine related trouble codes from Vehicle ECU (Electronic Control Unit) via check engine light, I/M monitor readiness test, view live data, view freeze frame data, read and clear codes etc, which is to say, it gets the complete 10 modes of OBDII test for technicians to diagnose the trouble fast and accurately as follows:
Mode 01: Request current power train diagnostic data.
Mode 02: Request freeze frame information.
Mode 03: Request emissions-related diagnostic trouble codes.
Mode 04: Clear/reset emissions-related diagnostic information.
Mode 05: Request oxygen sensor monitoring test results.
Mode 06: Request on-board monitoring test results for specific monitored systems.
Mode 07: Request emission-related diagnostic trouble codes detected during current or last completed driving cycle.
Mode 08: Request control of on-board system, test or component.
Mode 09: Request vehicle information.
Mode 10: Request emissions-related diagnostic trouble codes with permanent status after a clear/reset emission-related diagnostic information service.
Turning off the Check Engine Light
Malfunction Indicator Light (Service Engine Soon, Check Engine) is a term used for the light on the instrument panel, which is designed for alerting the drivers or the repair technicians that there is a problem with one or more vehicle's systems and those problems may cause emissions to exceed federal standards. With CR300, you are able to locate the error place and turn off the check engine light after completing the full diagnoses with ease.
For Passing Emission Test Smoothly
With this scan tool, you don't have to drive around endlessly, continuously coming back to the repair shop for the retest to check if all required tests by the ECU are completed. And you could also do a quick check of the vehicle to determine if it is ready to receive an emission test without the hassle of connecting your vehicle to the analyzer or having to use a complicated scan tool. It allows you to perform:
I/M readiness is used to check the readiness of the monitoring system. It is an excellent function to use prior to having a vehicle inspected for compliance to a state emissions program;
O2 Sensor Test allows retrieval and viewing of O2 sensor monitor test results for the most recently performed tests from the vehicle's on-board computer.
On-Board Monitor allows you to view the results of On-Board Monitor tests. The tests are useful after servicing or after erasing a vehicle's control module memory.
Quick Get Effective Diagnostic Result
Your repair work can be facilitated and then accomplished in a short time by using CR300 in the conformity of checking out the live data, freeze frame data and vehicle information as follows:
Live Data Stream: displays the real time PID data from ECU. The displayed data includes analog inputs and outputs, digital inputs and outputs, and system status information broadcast on the vehicle data stream.
Freeze Frame Data: When an emission related fault occurs, the OBD II system not only sets a code but also records a snapshot of the vehicle operating parameters to help identify the problem.
Vehicle Information: The option displays the vehicle identification number (VIN), the calibration identification, and the calibration verification number (CVN), and other information of the test vehicle.
Useful & Practical DTC Lookup Library
One of the best things about using the Launch CR300 as an engine code reader is that it has a lookup library, which is used to search for definitions of DTCs stored in the build-in DTC library and for DTC Guide information. Every code comes with a description to aid technicians in efficient vehicle diagnostics and repair.
Vehicle Coverage & Languages Supported
If you have an OBDII compliant vehicle, then chances are that Launch CR300 can help you diagnose it. This is because the scanner is compatible with most American, European, and Asian models manufactured as from 1996.It supports all OBDII protocols: KWP2000, ISO9141, J1850 VPW, J1850 PWM and CAN (Controller Area Network).
It also supports 9 languages that include English, Portuguese, Russian, Italian, Spanish, French, and German,ECT. The DIYers needs no effort in trying to get translations in as far as the code meanings and repair formulas are concerned.
Plug & Play, Not Require Any Battery
Launch CR300 OBD2 Scanner is “Plug and Play”, an independent device, doesn’t need to be powered from an external source, because it’s using the OBD connector supply voltage pins. You just need to connect the diagnostic cable into the vehicle’s DLC socket, and the code reader gets the power directly from the vehicle, which is very easy to use for beginners.
Other Abundant User-Friendly Features
The design tends to look strong and nice. In addition, several other enabling features will mean that you will be able to get a more enjoyable feel:
Easy-to-use keypad: The reader has four button keypad buttons that make the menu super easy to scroll. CR300 users can operate up and down, press OK or use the enter button pretty easily with a solid and effective touch to his delight.
Compact design: The reader has an compact ergonomic design which makes it fit in the palm quite comfortably, especially made for people who don’t want bulky devices. So that you can easily pack and carry it to anywhere.

NOTICE
By clearing trouble codes you also clear the readiness status for the individual emission system readiness tests. In order to reset these monitors, the vehicle must be driven through a complete drive cycle with no trouble codes in memory. Amount of time needed for reset vary by vehicle.
Do not erase the codes before repairs or services have been performed. Codes will again display if the underlining fault causing the code is not addressed.
Please close the anti-virus software in your PC when updating the device.
