MAHLE Test Systems Vehicle Communication Interface (VCI1000), or ComWorks™, enables high performance in a small package for an exceptional value. With wireless Bluetooth or USB connection, it supports industry standard and OE specific protocols. The wireless range of up to 300 feet allows the technician freedom to move about the vehicle without a diagnostic cable.


  • J2534 compliant device driver for a quick, seamless integration to diagnostic software
  • High speed handles CAN diagnostic packaged data with a ms inter-message time
  • Industry standard Bluetooth with 60 meter (200 feet) range - no cables to lose, break, or trip over and the technician can easily move the testing computer/laptop around the vehicle as they work
  • Small form factor, even with optional vehicle interfaces – easy to handle and transfer from one car to another
  • Near-instant start up, less than 1 second - no waiting to test
  • Battery and programming voltage monitoring via internal A/D
  • Fully potted electronics, industrial temperature rated electronics, and protective case - no worries about tester performance during "parking lot" diagnostics in the elements
  • Power consumption less than 100 mA - minimal drain placed on vehicle battery even for extended periods of time
  • USB connection available for those in RF heavy environments
  • Field Replaceable OBD connector – No need to buy a new device if the connector wears out or becomes damaged
