Vehicle-trailer electric connection tester

Type: DZP-1b



Modern and highly functional Vehicle-trailer electric connection tester used in vehicle inspection stations, services centers and repair garages.


  • complex testing of vehicle electric connecters and wiring systems of trailers (12 V and 24 V)
  • check of the continuity of wires in CAN bus (ABS/EBS)
  • measurement of voltage in connector contacts
  • measurement of voltage and current drops
  • detection of short-circuits in trailer wiring systems
  • measurement of power absorbed by trailer wiring systems
  • check of the continuity of wires in CAN bus of trucks and truck trailers (built-in CAN scanner – optional)


  • Bluetooth communications with PC
  • possible connection to the control unit of Uniline Quantum test lines and generating joint test reports
  • option of automatic circuits scanning,
  • storage of test results
  • easy in use by only one person
  • automatic checks of subsequent circuits in a tested wiring system
  • cables with only one junction (no need for changing cables while testing)
