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.
Connector 1:
- A2105403681 "6-PIN MQS;B29"
- Replacement/self built: VEMO V99-83-0013
- Pinout:
- 0.5 RedGreen: Circuit 87 (POWER)
- Not Connected
- Not Connected
- 0.5 GreenWhite: CAN-C High
- 0.5 Green: CAN-C Low
- 0.75 Brown: GROUND
Fitment:
- W219 (CLS)
- W211 (E), mounted with reflector (might need reflector to work properly?)
- W230 (SL)

Initialization
Bootup phase is about 30 seconds. The device needs to detect some particular frame in order to not deem itself faulty.
Communication
N47-5 (ESP, BAS control unit):
Note: W209/215/220 have a different interface compared to W211/219/230
- DTR controls engine and braking torque interface of ESP unit.
- ESP/BAS sends:
- Left front, right front, left rear, right rear wheel speeds
- Steering angle (0 to 720 degrees)
- Steering angle sign (right/left)
- ESP/BAS receives from DTR:
- Distronic error
- Target evaluation (distance to it, relative speed, angle, radar lobe orientation, strength of the reflected radar beams)
