ML 320 (163.154) V6-3.2L (112.942) (1998)
It receives operating data in the form of input signals from:
Starter interlock contact (Y3/6s1)
Rpm sensor 2 (Y3/6n2)
Rpm sensor 3 (Y3/6n3)
Transmission oil temperature sensor (Y3/6b1)
It is also linked over the engine compartment bus with:
Instrument cluster (A1)
Engine control module (ME-SFI) (N3/10)
Electronic selector lever module control module (N15/5)
Traction systems control module (N47)
Transfer case control module (N78)
The solenoid valves for the modulating and shift pressure and for the gear changes are actuated by the ETC control module (N15/3).
Function
The necessary pressure in relation to the torque to be transmitted, is computed from all the input signals. This involves the processing of the following
data from other systems:
Engine control module (ME-SFI) (N3/10)
Engine torque
Engine speed
Accelerator pedal position
Shift offset
Engine status
Electronic selector lever module control module (N15/5)
Kickdown switch (S1616)
Selector lever position
Traction systems control module (N47)
Wheel speeds
Shift offset Traction status
Transfer case control module (N78)
Position of transfer case (off-road or on-road ratio)
The following information is output over CAN-C:
Engine control module (ME-SFI) (N3/10)
Kickdown switch (S16/6)
Engaged drive mode
Selector lever position P/N
Traction systems control module (N47)
Transmission ratio
Wheel speeds
Instrument cluster (A1)
Selector lever position / shift range
