Convertible Top Control Module: Description and Operation
GF77.39-P-3310-01SK Vario Roof Control Module, Purpose
GF77.39-P-3310-01SK Vario Roof Control Module, Purpose
- up to model year 08
Tasks
The power soft top control module (N52) controls opening and closing of the Vario roof
This is accomplished via
^
the Vario roof actuation switch (S84s1) or
^
the control key (A8/1) with an infrared signal (IR signal) (with code (880a) Closing system with infrared remote control).
Control
^
Open soft top mechanism hydraulic unit (A7/5) with Vario roof relay (A7/5k1), close with Vario roof relay (A7/5k2) as well as the Vario roof
solenoid valve (A7/5y1)
^
Left rear power window motor (M10/5)
^
Right rear power window motor (M10/6)
^
Output of function and warning displays via the controller area network bus class B (passenger compartment (CAN B), indicated in the instrument
cluster (A1)
Signals via CAN B bus
The power soft top control module (N52) transmits and receives signals via the CAN B bus
The most important signals:
^
Locking front Vario roof via CAN B bus with overhead control panel control module (N70).
^
Rotary tumbler as well as lock pawl of trunk lid lock closed with rear SAM control module with fuse and relay module Fond (N10/2) via CAN B
bus.
^
Shift position of Vario roof actuation switch (S84s1) with overhead control panel control module (N72/1) via CAN B bus.
^
Speed signal from instrument cluster via CAN-B bus (A1).
^
Actuation of left front power window motor (M10/3) with left door control module (N69/1) via CAN-B bus
^
Actuation of right front power window motor (M10/4) with right front door control module (N69/2) via CAN B bus
