BRAKE LAMP SWITCH
DESCRIPTION
The brake lamp switch is located under the instru-
ment panel, at the brake pedal arm (Fig. 3). It has
three internal switches controlling various functions
of the vehicle. It's main function is to control opera-
tion of the vehicle's brake lamps. Other functions
include speed control deactivation, brake sense for
the antilock brake system and brake sense for the
brake transmission shift interlock.
CAUTION: The switch can only be adjusted once.
That is during initial installation of the switch. If the
switch is not adjusted properly or has been
removed for some service, a new switch must be
installed and adjusted.
OPERATION
When the brake pedal is pressed, the plunger on
the outside of the brake lamp switch extends out-
ward. This action opens or closes the contacts of the
three switches inside the brake lamp switch.
With the brake pedal is pressed down (plunger
extended), the switch for terminals 1 and 2 is closedcompleting the circuit. The switch for terminals 3
and 4 is open and so is the switch for 5 and 6.
When the brake pedal is released (plunger pushed
in), the three switches assume the opposite positions.
The switch for terminals 1 and 2 is now open while
the other two switches are now closed, completing
their circuits.
DIAGNOSIS AND TESTING - BRAKE LAMP
SWITCH
NOTE: Before proceeding with this diagnostic test,
verify the adjustment of the brake lamp switch to
rule out misadjustment. If misadjusted, replace the
switch. It cannot be readjusted.
If the electrical circuit has been tested and the
brake lamp switch is suspected of being faulty, it can
be tested using the following method.
(1) Remove the switch from the vehicle. Refer to
Removal And Installation in this section.
(2) With the switch in the released position (plung-
er extended), use an ohmmeter to test each of the
three internal switches as shown (Fig. 1). You should
achieve the results as listed in the figure.
(3) Gently push the plunger on the brake lamp
switch in until it stops.
(4) With the switch in this depressed position
(plunger pushed in), use an ohmmeter to test each of
the three internal switches as shown (Fig. 2). You
should achieve the results as listed in the figure.
If you do not achieve the results as listed in both
figures, the switch is faulty and must be replaced.
Refer to Removal And Installation in this section.
If the switch is found to be operating properly, do
not reinstall it, replace the switch. Refer to Removal
And Installation in this section.

RSLAMPS/LIGHTING - EXTERIOR8L-7

CAUTION: The switch can only be adjusted once.
That is during initial installation of the switch. If the
switch is not adjusted properly or has been
removed for some service, a new switch must be
installed and adjusted.
REMOVAL - BRAKE LAMP SWITCH
(1) Disconnect and isolate the battery negative
cable from its post on the battery.
(2) Remove silencer panel below steering column
and knee blocker.
(3) Remove the brake lamp switch by rotating the
switch in a counterclockwise direction approximately
30 degrees and pulling it out of the bracket (Fig. 3).
(4) Discard the brake lamp switch. It must not be
reused.
INSTALLATION - BRAKE LAMP SWITCH
CAUTION: Do not reuse the original brake lamp
switch. The switch can only be adjusted once. That
is during initial installation of the switch. If the
switch is not adjusted properly or has been
removed for some service, a new switch must be
installed and adjusted.
(1) Mount and adjust the NEW brake lamp switch
using the following procedure:
(a) Install the switch in its bracket by aligning
the index tab on the switch with the slot in the
mounting bracket.
(b) When the switch is fully seated in its
bracket, rotate the switch clockwise approximately
30É to lock the switch into place (Fig. 3).
(c) With the brake pedal in the fully released
position, move the lever on the back of the brake
lamp switch from the angled non-adjusted positionto the full vertical position as shown (Fig. 4). This
will adjust the brake lamp switch to the vehicle.
(2) Install silencer panel below steering column
knee blocker.
(3) Reconnect the battery negative terminal.
(4) Check the stop lamps to verify they are operat-
ing properly and not staying on when the pedal is in
the released position.
(5) Road test the vehicle to ensure proper opera-
tion of the brakes (including ABS if equipped) and
speed control (if equipped).

ADJUSTMENT
FOG LAMP ALIGNMENT
Prepare an alignment screen. (Refer to 8 - ELEC-
TRICAL/LAMPS/LIGHTING - EXTERIOR/HEAD-
LAMP UNIT - ADJUSTMENTS). A properly aligned
fog lamp will project a pattern on the alignment
screen 100 mm (4 in.) below the fog lamp center line
and straight ahead (Fig. 8). To improve visual inter-
pretation of the fog lamp pattern on the alignment
screen, the headlamps should be in the ªoffº position.
The fog lamps are adjusted by a adjustment screw
located through the lens on Dodge vehicles, and by a
knob on the back of the lamp on Chrysler vehicles.

tern should be correct when the low beams are
aligned properly (Fig. 14). To adjust headlamp verti-
cal alignment, rotate adjustment screw to achieve the
specified low beam cut-off location.

MULTI-FUNCTION SWITCH
DESCRIPTION - TURN SIGNAL SYSTEM
The turn signals are actuated with a lever on
Multi-Function Switch, located on the left side of the
steering wheel. The signals are automatically turned
off by a canceling cam (two lobes molded to the clock
spring mechanism). The cam comes in contact with
the cancel actuator on the turn signal (multi-func-
tion) switch assembly. Either cam lobe, pushing on
the cancel actuator, returns the switch to the OFF
position. The multi-function switch is a resistive
MUX switch that feeds inputs to the BCM.

OPERATION - TURN SIGNAL SYSTEM
Lane change signaling is actuated by applying par-
tial turn signal stalk movement toward the direction
desired until the indicator lamps flashes in the
instrument cluster. When the switch stalk is released
the stalk will spring back into the neutral position
turning OFF the turn signal.
With the ignition switch ON and the turn signal
switch stalk actuated left or right, current flows
through the:
²Multi-function switch
²Body Control Module
²Integrated Power Module (IPM)
²Turn indicator lamp
²Front and rear turn signal bulbs.
A chime will sound after the vehicle has traveled a
distance of approximately 0.5 mile and a speed of 15
mph, with the turn signal ON.
DIAGNOSIS AND TESTING - MULTI-FUNCTION
SWITCH
To test turn signal, headlamp beam select and opti-
cal horn portion of the multi-function switch:
(1) Remove the multi-function switch, refer to
Electrical, Lamps/Lighting - Exterior, Multi-Function
Switch, Removal, and Installation.
(2) Using an ohmmeter check the continuity read-
ings between multi-function switch pins. Refer to
