ML 500 (163.175) V8-5.0L (113.965) (2003)
-
Transmission oil temperature sensor (Y3/6b1)
In addition there is a connection via the engine compartment bus to the:
-
Instrument cluster (A1)
-
ME-SFI control module (N3/10) or CDI control module (N3/9)
-
Electronic selector lever module control module (N15/5)
-
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
Electronic selector lever module control module (N15/5)
-
Kickdown switch (S16/6)
-
Selector lever position
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
-
Selector lever position P/N
Traction system control module (N47)
-
Transmission ratio
-
Speeds
Instrument cluster (A1)
-
Selector lever position / shift range
