ML 320 (163.154) V6-3.2L (112.942) (1998)
-
Rpm sensor 3 (Y3/6n3)
-
Transmission oil temperature sensor (Y3/6b1)
-
Kickdown switch (S16/6)
-
Gear recognition switch (S16/10)
Output signals:
-
Reverse/parking lock valve (Y66/1)
-
Selector lever position P/N to the engine control module (ME-SFI) (N3/10)
(only on detection of the selector lever position "P" or "N" on the transmission range recognition switch (S16/10) and at the starter interlock
contact (Y3/6s1))
Input and output signals:
-
Datalink connector (X11/4)
In addition there is a connection via the engine compartment bus to the:
-
ME-SFI control module (N3/10) or CDI control module (N3/9)
-
Traction system control module (N47)
-
Transfer case control module (N78)
The solenoid valves for the modulating and shift pressure and for the gearchanges are actuated by the ETC control module (N15/3).
The pressure required is calculated from all input signals, adjusted to the torque to be transferred.
The following information from other systems is then processed:
ME-SFI control module (N3/10) or CDI control module (N3/9)
-
Engine torque
-
Engine speed
-
Accelerator pedal position
-
Gear shift
-
Engine status
Traction system control module (N47)
-
Wheel speeds
-
Gear shift
-
Traction status
Transfer case control module (N78)
-
Position of transfer case (off-road or on-road ratio)
The following information is output to other systems:
ME-SFI control module (N3/10) or CDI control module (N3/9)
-
Kickdown switch (S16/6)
-
Engaged drive mode
Traction system control module (N47)
-
Transmission ratio
-
