OBDSTAR MT203 CAN Driver Gateway Simulator  ​

MT203 CAN driver/Gateway simulator is a tool designed for automotive electronics maintenance and repair. It provides CAN drive and gateway simulation function, supports multiple vehicles, and is a compact device, which is a good helper for automotive electronics maintenance engineers!  OBDSTAR MT203 is one of the most unique products in the automotive industry. Produced by OBDSTAR, it allows to simulate a vehicle gateway in order to allow access to ECUs which normally require a Gateway module connected to it. ​ ​OBDSTAR MT203 solves much of these problems and more: besides the gateway function, it also has its own vehicle module platform testing functions. The cluster needs a CAN message to light up? MT203 can do it for you on its own. Same thing for dozens of modules, from gear selector on Land Rover to the 48V alternator used on Audi Mild Hybrid, as well as many infotainment modules. ​ ​Dealer code: 0086A002 ​ ​OBDSTAR MT203 Coverage (2024-10)

Background

1. CAN Drive Function

The Dash, Audio, Gear Lever, Handbrake and other modules of latest vehicles enter working state mainly through CAN transmission, however, occasionally automotive technicians servicing the module are detaching from vehicle CAN network, thus causing no operational status. This function can simulate CAN communication to wake up the ECU module, so that the module can enter the working state, which can be tested and verified. It also saves the need to purchase a large number of startup platforms and wiring harnesses for various vehicle models, reducing costs for automotive technicians.

2. Gateway Function

At present, an increasing majority of automobiles are designed with gateway modules for security and efficiency reasons, the majority of ECU modules and diagnostic scanner requires a gateway to pass through the protocol type and baud rate to accomplish the communication. When the ECU module needs to be detected with the diagnostic scanner, it requires an additional connection to the corresponding model’s gateway to complete the transmission, which greatly causes inconvenient detection. MT203 gateway simulator works to emulate the majority of automotive gateways to accomplish various types of protocols and baud rate conversion, and the diagnostic scanner provides an efficient way to communicate with the ECU module. Eliminates the need to purchase different gateways for various models and create wiring test platforms, reducing costs for automotive technicians.

Applicable Maintenance Scenarios

1. Automotive electronic ECU repair (Airbag, Dash, BCM and other modules simulation gateway diagnostic test by BENCH)

2. Automotive electronic ECU repair (Dash, Audio, Gear Lever, AC panel and other modules CAN drive test by BEHCH)

3. E-car components repair (Compressor, DCDC, On-board charger and other modules simulation gateway diagnostic test by BENCH) ​

It looks like a professional device for fairly advanced electronic repair businesses, however in our opinion MT203 is so cheap that it entirely pays itself back even if you need to use it just once a month. ​Next time you test a cluster or a module which requires special commands or a gateway, save yourself the time to look for a module somewhere in your lab and just plug MT203 to it. ​
