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.

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 0A: Request emissions-related diagnostic trouble codes with permanent status after a clear/reset emission-related diagnostic information service.

Turning off the Check Engine Light

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 Yet Effective Diagnostic Result

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 CR3001 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.

Vehicle Coverage & Languages Supported

If you have an OBDII compliant vehicle, then chances are that Launch CR3001 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 seven languages that include English, Portuguese, Russian, Italian, Spanish, French, and German.
