Location
The ETC control module (N15/3) is located in the control module box on the right of the engine compartment.
Task
The transmission control ETC control module (N15/3) determines the current operating status of the vehicle and controls all the shift sequences taking into account shift quality and the driving situation.
It receives operating data as input signals from the:
^ Starter interlock contact (Y3/6s1)
^ Transmission fluid temperature sensor (Y3/6b1)
^ RPM sensor 1 (Y3/6l1)
^ RPM sensor 2 (Y3I6l2)
Via the engine compartment bus there is also a connection to the:
^ Instrument cluster (A1)
^ Engine control module (ME-SFI) (N3/10)
^ Electronic shift lever module control module (N15/5)
^ Traction Systems control module (N47)
^ Electronic ignition/starter switch control module (N73)
The ETC control module (N 15/3) actuates the solenoid valves for modulating and shift pressure and gear change.
Function
To match the torque to be transmitted. the required pressure level is calculated from all the input signals with the following information processed:
Engine control module (ME-SF1)(N3/10)
^ Engine torque
^ Engine speed
^ Accelerator pedal position
^ Shift adjustment
^ Engine status
Electronic shift lever module control module (N15/5)
^ Kickdown switch (S16/6)
^ Selector lever position
^ W/S program selection button
Traction systems control module (N47)
^ Wheel speed
^ Shift adjustment
^ Traction status
Electronic ignition/starter switch control module (N73)
The electronic ignition/starter switch control module (N73) forms the Gateway (connection) between the engine compartment bus (CAN C) and the interior bus (CAN B). The ETC control module (N15/3) receives the following input signal from the AAC pushbutton control module (N22) via the electronic ignition/starter switch control module (N73).
^ A/C compressor torque
The following information is output to the instrument cluster (A1) via CAN.
^ Selector lever position(shift range
^ Program selection
