Mercedes-Benz Sprinter / Dodge Sprinter. Manual - part 196

The Steering Angle Sensor is used to measure rate/

speed and direction of the steering wheel. This sen-
sor has 4 wires 12V, ground and 2 CAN Bus circuits.
This sensor is wired directly to the CAN Bus. This
sensor has to be programmed using the DRB III

(Fig. 5).

RESTRAINTS/AIRBAG

CONTROL

MODULE

INSTALLATION).

(8) Reconnect the battery.
(9) Recalibrate the steering angle sensor using the

scan tool.

LATERAL ACCELERATION
SENSOR

DESCRIPTION

The Yaw Rate and Lateral Acceleration Sensor is

housed into one unit (Fig. 7) (each individual sen-
sor can not be replaced separately the whole
housing unit must be replaced when servicing).
The sensor is used to measure side to side (Lateral)
motion and vehicle rotational sensing (how fast the
vehicle is turning). This is a 6–wire sensor with all
six wires connected to the ESP/ABS module.

REMOVAL

(1) Disconnect the battery.
(2) Move the drivers seat forward and upwards.

YAW RATE SENSOR

DESCRIPTION

The Yaw Rate and Lateral Acceleration Sensor is

housed into one unit (Fig. 12) (each individual sen-
sor can not be replaced separately the whole
housing unit must be replaced when servicing).
The sensor is used to measure side to side (Lateral)
motion and vehicle rotational sensing (how fast the
vehicle is turning). This is a 6–wire sensor with all
six wires connected to the ESP/ABS module.

REMOVAL

(1) Disconnect the battery.
(2) Move the drivers seat forward and upwards.

(3) Remove the cover below the drivers seat (Fig.

13).

(4) Remove the bracket for the control modules

and set aside with the control modules (Fig. 14).

(5) Remove the screws securing the Yaw rate/lat-

eral Acceleration Sensor (Fig. 15).

HCU (HYDRAULIC CONTROL
UNIT)

DESCRIPTION

The HCU consists of a valve body, pump motor, low

pressure accumulators, inlet valves, outlet valves and
noise attenuators.

REMOVAL

NOTE: Store the Hydraulic Control Unit in an
upright position only.

(1) Disconnect the ground cable at the battery.

The ignition switch must be switched to the off
position when disconnecting the battery cable.

(2) Disconnect the multiplug from the control mod-

ule (Fig. 17).

(3) Disconnect the brake lines from the hydraulic

control unit (Fig. 17). Mark the brake lines for
reinstallation, also seal off the connections and
lines to prevent contamination.

(4) Remove the hydraulic control unit from the

bracket (Fig. 17).

(5) Check the rubber mounts on the bracket.

(Replace if necessary) (Fig. 17).
