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 pressed down (plunger
extended), the switch for terminals 1 and 2 is closed
completing the circuit. The switch for terminals 3
and 4 is open and so is the switch for terminals 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.
A lever on the back of the switch is used to set the
switch into the ªadjustedº position. A non-adjusted
switch will have the lever set to the diagonal position
in relation to the switch housing. The plunger can be
moved in and out, but the states of the internal
switches will not change.
CAUTION: Never move the adjustment lever of the
new brake lamp switch without it being properly
installed in the vehicle first. Such action will render
the switch unusable and the switch must be dis-
carded.
Once installed in the vehicle as described in the
brake lamp switch installation procedure (Refer to 8 -
ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/
BRAKE LAMP SWITCH - INSTALLATION), the new
switch's adjustment lever is rotated to the adjusted
position as indicated (Fig. 4). This action locks the
plunger to the internal switches.Once in this posi-
tion the switch is permanently adjusted (or
locked) and cannot be readjusted or released
even if the lever is moved back.
DIAGNOSIS AND TESTING - BRAKE LAMP
SWITCH
NOTE: Before proceeding with this diagnostic test,
verify the adjustment lever on the back of the
switch is in the adjusted position. If the lever is in
the non-adjusted (diagonal) position it may have
never been adjusted (Refer to 8 - ELECTRICAL/
LAMPS/LIGHTING - EXTERIOR/BRAKE LAMP
SWITCH - OPERATION). For adjustment, (Refer to 8
- ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/
BRAKE LAMP SWITCH - INSTALLATION)
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.

INSTALLATION
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) Connect the wiring connector to the switch
and latch the locking tab.
(b) Install the switch in its bracket by aligning
the index tab on the switch with the slot in the
mounting bracket.
(c) When the switch is fully seated in its
bracket, rotate the switch clockwise approximately
30É to lock the switch into place (Fig. 3).
(d) 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 position
to 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 and speed control (if
equipped).

FOG LAMP
DIAGNOSIS AND TESTING - FOG LAMP
When a vehicle experiences problems with the fog
lamp system, verify the condition of the battery con-
nections, fuses, charging system, fog lamp bulbs, wire
connectors, relay, high beam switch, and headlamp
switch. Refer to the appropriate wiring information.
Each vehicle is equipped with various lamp assem-
blies. A good ground is necessary for proper lighting
operation. Grounding is provided by the lamp socket
when it comes in contact with the metal body, or
through a separate ground wire.
When changing lamp bulbs check the socket for
corrosion. If corrosion is present, clean it with a wire
brush.
When it is necessary to remove components to ser-
vice another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges are not holding the com-
ponent in place.
