Mercedes-Benz Sprinter / Dodge Sprinter. Manual - part 229

TURN SIGNAL LAMPS

When the left (lighting) control stalk of the multi-

function switch is activated (Fig. 1), the turn signal
system illuminates the selected right or left turn sig-
nal indicator and the turn signal lamps begin to
flash. The turn signal lamps include a bulb integral
to each front lamp unit and each tail lamp unit, as
well as a repeater lamp bulb located on each front
fender above the front wheels. When the turn signal
system is activated, the turn signal switch circuitry
within the multi-function switch and the electronic
circuitry of the wipers, turn signals and engine start
control module within the fuse block will repeatedly
energize and de-energize the turn signal relay
located in the fuse block. The turn signal relay
switches battery current from a fused ignition switch
output fuse in the fuse block to the appropriate turn
signal indicator and turn signal lamps.

The ElectroMechanical Instrument Cluster (EMIC)

contactless relay will generate repetitive, audible
turn signal “click” sounds to emulate the sounds of a
conventional electro-mechanical turn signal flasher
at one of two rates to coincide with the flashing of
the turn signals. The slow rate emulates normal turn
signal operation, while the fast rate emulates “bulb
out” turn signal operation.

push the two latch tabs toward the center of the tail
lamp unit socket plate and pull the socket plate
straight out from the inner rear pillar (Fig. 2).

socket plate (Fig. 3).

(2) Align the socket plate with the mounting hole

in the inner rear pillar.

(3) Using hand pressure, push the socket plate

gently and evenly into the inner rear pillar mounting
hole until both latch tabs are fully engaged (Fig. 2).

BRAKE LAMP SWITCH

REMOVAL

WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental

restraint

system

before

attempting

any

steering wheel, steering column, airbag, seat belt
tensioner, or instrument panel component diagno-
sis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for
the system capacitor to discharge before perform-
ing further diagnosis or service. This is the only
sure way to disable the supplemental restraint sys-
tem. Failure to take the proper precautions could
result in accidental airbag deployment.

(1) Disconnect and isolate the battery negative

cable.

(2) Locate the brake lamp switch on the pedal

bracket underneath the instrument panel (Fig. 4).

(3) Depress the locking tab on the brake lamp

switch body behind the pedal bracket and rotate the
switch counterclockwise about 30 degrees (Fig. 5).

(4) Pull the switch forward in the vehicle far

enough to disengage the switch plunger from the
mounting hole in the pedal bracket.

(5) Disconnect the vehicle wire harness from the

brake lamp switch connector receptacle.

(6) Remove the brake lamp switch from the vehi-

cle.

system

before

attempting

any

(1) Pull the plunger of the brake lamp switch out-

ward from the switch body to its travel limit (Fig. 5).

(2) Reconnect the vehicle wire harness to the

brake lamp switch connector receptacle.

(3) Depress and hold the brake pedal in the

depressed position until the brake lamp switch
installation is completed (Fig. 4).

(4) Insert the brake lamp switch plunger through

the mounting hole from behind until the switch lock-
ing collar is fully seated against the pedal bracket.

(5) Rotate the brake lamp switch clockwise until

the locking tab on the switch body fully engages the
pedal bracket. Full locking tab engagement will be
accompanied by an audible click.

NOTE: Do not pull the brake pedal upwards as this
will adjust the switch plunger to an incorrect posi-
tion. The switch is properly adjusted when the
switch plunger is just contacting (no gap) the brake
pedal arm with the pedal in the relaxed (released)
position.

(6) Release the brake pedal from its depressed

position to automatically adjust the brake lamp
switch plunger.

(7) Reconnect the battery negative cable.
