1997 MERCEDES-BENZ ML430 traction control

The ETC control module (N15/3) determines the instantaneous operating condition of the vehicle and controls
all gearshift sequences taking into account the ease of shifting and the driving situation. See Fig. 158
. This
involves receiving , converting and transmitting various digital and analog signals.
Input Signals:
Starter Lock-Out Contact (Y3/6S1)
RPM Sensor 2 (Y3/6N2)
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
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 gear changes 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)
Reverse And Parking Lock Solenoids (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)).
Traction System Control Module (N47):
Wheel Speeds
Gear Shift
Traction Status

Oil Level Control, Function
Operation - The oil level control system seals the opening between the oil gallery and gearset chamber so that
the rotating gearsets do not splash about in oil as the oil level rises. The oil level control reduces power loss and
prevents oil from being thrown out of the transmission housing at high oil temperatures.

Fig. 47: Identifying Basic Location Finding, Function

Basic location finding (dead reckoning)
Is the basic function of permanent location finding It is accomplished permanently by the navigation processor
when the ignition is switched on and is not dependent on the CD-ROM map.
The current position is stored after the ignition is switched off.
The following information is calculated with the aid of basic location finding :
Distance traveled
Direction of motion (forward or backward) and
Direction in which vehicle is pointing
Basic location finding is accomplished approx. once per second .
Distance traveled
The navigation processor receives the signals output by the front right wheel speed sensor (L6/2) from the
traction system control module (N47) via discrete leads.
Evaluation of the wheel speed signals allows calculation of the distance traveled.
