with CODE 890 (EASY-PACK liftgate) 

Shown on model 166.0 

Task 

The liftgate control unit has the following purposes:

• Reading in of sensors and signals 

Reading in of sensors and signals 

The input factors are read in via the following connections:

• Direct line 
• Interior CAN (CAN B) 

Direct line 

The signals from the following components are read via direct lines:

• Liftgate control Hall sensor (M51/3b1)
• Liftgate control position sensor (M51/3b2)
• Left EASY-PACK liftgate anti-pinch protection contact bar (B86/1)

Actuation of components 

The liftgate control unit actuates the following components via direct lines:

Transmitting signals 

The following signals are transmitted via the interior CAN:

• Open liftgate, request

Location 

The liftgate control unit is located in the right rear sidewall below the side window.

• Evaluation of input factors 
• Actuation of components 
• Transmitting signals 
• Right EASY-PACK liftgate anti-pinch protection contact bar (B86/2)

Interior CAN 

The following signals are read in over the interior CAN:

• Vehicle speed
• Status of driver trunk lid/liftgate control button (S15/3)
• Status of liftgate rotary tumbler switch (M14/7s1)
• Status of liftgate control button (S62/36)
• Terminal status of terminal 15
• Status of liftgate open/close button on transmitter key (A8/1)

Evaluation of input factors 

The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

• Liftgate control warning buzzer (H4/60)
• Liftgate control electric motor (M51/3m1)
• Switch on illumination for liftgate control unit (status feedback)
• Position of liftgate
