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 via a brake switch
input to the BCM. The BCM will then activate the
stop lamps. Other functions include speed control
deactivation, brake sense for the antilock brake sys-
tem 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.
(1) Remove the switch from the vehicle. (Refer to 8
- ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/
BRAKE LAMP SWITCH - REMOVAL)
(2) With the switch in the released position
(plunger 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.

Anytime the liftgate is opened or closed using the
power liftgate system the power liftgate control mod-
ule learns from the cycle. If a replacement power lift-
gate component is installed or a liftgate adjustment
is made, the module will relearn the effort and/or
time required to open or close the liftgate. This learn
cycle can be performed with a DRB IIIt, or equiva-
lent scan tool, or with a complete cycle of the liftgate,
using any one of the command switches. (Refer to 8 -
ELECTRICAL/POWER DOORS - STANDARD PRO-
CEDURE) for detailed instructions.
The power liftgate system is designed with a num-
ber of system inhibitors. These inhibitors are neces-
sary for safety and / or feasibility of the power
liftgate system. The power liftgate system inhibitors
are:
²The Power Liftgate may not operate in extreme
temperatures. These extreme temperatures will be
approximately less than -12É F (-24.4É C) or greater
than 143É F (61.6É C). A chime/thermister assembly
in the rear light bar assembly monitors the outside
temperature.
²The vehicle transmission must be in Park or
Neutral for the power liftgate to start a cycle.
²If multiple obstacles are detected during the
same power open or close cycle, the liftgate goes into
manual operation.
²If severe problems occur, Diagnostic Trouble
Codes (DTC) are stored in the power liftgate control
module.
POWER LIFTGATE SYSTEM CAUTIONS AND
WARNINGS
WARNING: ALWAYS DISCONNECT THE BATTERY
NEGATIVE CABLE BEFORE ATTEMPTING ANY
POWER LIFTGATE SYSTEM SERVICE.
WARNING: THERE IS A SMALL AREA ON BOTH
SIDES OF THE LOWER POWER LIFTGATE WHICH
IS NOT PROTECTED BY PINCH SENSORS.
EXTREME CARE MUST BE TAKEN TO PREVENT
OBJECTS FROM ENTERING THIS AREA ONCE THELIFTGATE REACHES THE SECONDARY LATCH
CONTACT (APPROXIMATELY 1/2 INCH BEFORE
FULLY CLOSED).
WARNING: NEVER ATTEMPT TO ENTER OR EXIT
THE VEHICLE WITH THE LIFTGATE IN MOTION.
YOU COULD DAMAGE THE POWER LIFTGATE SYS-
TEM AND/OR COMPONENTS AND/OR CAUSE PER-
SONAL INJURY.
WARNING: NEVER STICK OBJECTS IN THE POWER
LIFTGATE WHEN CINCHING CLOSED. YOU COULD
DAMAGE THE VEHICLE, POWER LIFTGATE SYS-
TEM COMPONENTS AND/OR CAUSE PERSONAL
INJURY.
DIAGNOSIS AND TESTING
POWER LIFTGATE SYSTEM
The power liftgate system contains many compo-
nents and modules. In order to obtain conclusive
testing the Programmable Communications Interface
(PCI) data bus network and all of the electronic mod-
ules that provide inputs to, or receive outputs from
the power liftgate system must be checked.
The power liftgate system can be diagnosed with
an appropriate scan tool, such as the DRB IIItor
equivalent. The DRB IIItcan be used to observe var-
ious switch statuses throughout the power liftgate
system to help diagnose an inoperative switch or
component. The DRB IIItcan also be used to actuate
various components throughout the power liftgate
system to help diagnose an inoperative component.
Before any testing of the power liftgate system is
attempted, the battery should be fully charged, all
built-in power liftgate system inhibitors read and
understood, and all wire harness and ground connec-
tions inspected around the affected areas on the vehi-
cle.
The following are quick reference diagnostic tables
to help when diagnosing and testing the power lift-
gate system.
