Distronic

Radar

Name: ART2 B (aka Distronic Plus), "ART210", DTR2

Mercedes part ID: A89 (A89b1 DTR Radar Sensor and A89n1 DTR Control Module integrated in single unit)

This device has only a single connector. This connector is close to VEMO V99-83-0013, but you have to cut the plastic to fit. On older models (ART1), a secondary unit is required and is has a coaxial cable running to it. The plug this coaxial cable is connected to, is used as a venting hole on ART2 / DTR2. Its a much more complex system, check W220 wiki for more information.

• A2105403681 "6-PIN MQS;B29"
• Replacement/self built: VEMO V99-83-0013
• Pinout:
  1. 0.5 RedGreen: Circuit 87 (POWER)
  2. Not Connected
  3. Not Connected
  4. 0.5 GreenWhite: CAN-C High
  5. 0.5 Green: CAN-C Low
  6. 0.75 Brown: GROUND
