Operation - If the inner race (13) of the freewheel is locked and the outer race (12) turns in direction "A" , the
locking elements (14) adopt a diagonal position on account of their special contours, allowing the freewheel
function. See Fig. 38
. The outer race (12) slides over the locking elements (14) with negligible friction. If the
rotation of the outer race (12) changes to direction "B", the locking elements (14) stand up and lock the outer
and inner races (12, 13) together.

Task - The ETC control module (N15/3) determines the instantaneous operating condition for the vehicle and
controls all gearshift sequences taking into account the ease of shifting and the driving situation. See Fig. 97
.
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)
(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)).

Function Of Gear Shift (With Touch Shift)
Transmission with touch shift.
On transmission 722.6 the electrohydraulic control unit converts the electric signals going out from the
electronic transmission control (EGS) into hydraulic signals.
Faults occurring in the ETC control unit (N15/3) are handled by the limp-home system. The limp-home system
is designed so that the driver can reach a Service Operation even under extreme conditions.
Selector lever position "P", "R", "N" and "D" are transmitted by the electronic selector lever module control unit
(N15/5) on the Controller Area Network bus class C (engine compartment) (CAN-C) and in parallel to this by
means of a shift rod to the range selector lever at the transmission end. By touching or holding the selector lever
towards "+" or "-" the shift range is pre-selected and displayed in the instrument cluster (A1) until an upshift of
transmission 722.6 is possible.

Fig. 3: Identifying Position Of Identification On Fiber Optic Cable Wiring Harness
Routing
The inserts (5) of the fiber optic cable modules may only be routed as in production. The fiber optic cable
modules must always be pr ovided with a protective cap when routing. For every vehicle model, the sequence of
components in the D2B ring is specifically predetermi ned. The components are connected by fiber optic cable
modules. They are secured to a wiring ha rness with an orange-colored casing.
Fig. 4: Identifying Fiber Optic Cable Modules Insert

Danger of breaking! Do not kink fiber optic cable, route over sharp edges or be nd in radii smaller than 25
mm. Tensile forces on inserts must not exceed 65 N.
The fiber optic cable must not be exposed to temperat ures greater than 85°C or lower than -40°C. Do not
squeeze fiber optic cable, in other words do not compress with clamps or cable ties.
Connection between the devices
The Digital Data Bus ring (D2B) connects the new ra dio generation and COMAND (monitor) to the CD
changer (CDC) (USA preinstallati on), telephone and portable CTEL. The sound amplifier remains wired as
COMAND (monitor) to the CD changer (CDC) (USA preinstallation), telephone and portable CTEL. The sound
amplifier remains wired as befo re with Models 129, 170, 202, 208 and 210. The radio and COMAND as head
unit (HU) performs the master function and also forms the interface to the Control Area Network bus Class B
(interior) (CAN-B) (for vehicles wi th multifunction steering wheel).
