MODEL 212.2
Location
The liftgate control unit is fastened in the cargo area below the cover.
Task
The liftgate control unit has the following purposes:
- Reading in of sensors, pickups and signals
- Evaluation of input factors
- Actuation of components
Reading in of sensors, pickups and signals
The input factors are read in with the following connections:
- Direct line
- Interior CAN (CAN B)
Direct line
The signals from the following components are read via a direct line:
- Liftgate control Hall sensor (M51/3b1)
- Liftgate control position sensor (M51/3b2)
Interior CAN
The following signals are read in over the interior CAN:
By the left front door control unit (N69/1):
- Status of driver liftgate control button (S15/3)
By the rear SAM control unit with fuse and relay module (N10/2):
- Status of liftgate rotary tumbler switch (M14/7s1)
- Status of liftgate control button (S62/36)
- Status of liftgate external operation switch (S88/8)
