pigtail wires are also captured between a covering
and the adhesive foam rubber backing. The heated
seat sensors are Negative Thermal Coefficient (NTC)
thermistors. The sensors for both front seats receive
a voltage feed from a single output of the heated seat
module, but the module receives individual sensor
inputs from the driver side and passenger side sen-
sors.
The heated seat elements and sensors should not
be repaired. If damaged or faulty, the heated seat ele-
ment assembly must be replaced.
OPERATION
One end of the heated seat element resistor wire is
connected to ground at all times through a splice in
the heated seat module ground circuit. Battery cur-
rent is directed to the other end of the heated seat
element resistor wire by the energized N-channel
Field Effect Transistor (N-FET) located within the
heated seat module. The heated seat module will
energize the N-FET only when the heated seat
switch is in the Low or High position and the heated
seat sensor indicates that the seat cushion surface
temperature is below the selected (Low or High) tem-
perature set point. As electrical current passes
through the heating element grid, the resistance of
the wire used in the element disperses some of that
electrical current in the form of heat. The heat pro-
duced by the heated seat element grid then radiates
through the seat trim cover, warming its occupant.
The resistance of the heated seat sensor increases
and decreases as the surface temperature of the seat
cushion cover changes. The heated seat module sup-
plies each sensor with a 5v voltage feed, then uses
the sensor resistance to determine when the heated
seat element grids need to be cycled on or off in order
to maintain the selected temperature set point.
DIAGNOSIS AND TESTING - HEATED SEAT
ELEMENT
The heated seat module will self-diagnose shorted
or open heated seat element circuits and sensor cir-
cuits. Refer to Heated Seat System Diagnosis and
Testing in this section for additional diagnosis and
testing procedures. To manually check the heated
seat element, proceed as follows. The wire harness
connectors for the seat cushion and seat back heating
elements and sensor are located on the right side of
the seat, near the edge of the seat cushion frame.
The proper connector can be identified by the foam
wrapping.
NOTE: When checking heated seat elements for
continuity, be certain to move the heating element
being checked. Moving the element, such as sitting
in the seat will eliminate the possibility of an inter-mittent open in the element which would only be
evident if the element was in a certain position.
Failure to check the element in various positions
could result in an incomplete test.
(1) Position the appropriate seat in the full for-
ward position.
(2) Make certain the ignition switch is in the OFF
position.
(3) Disconnect the heated seat element connector
which requires testing. Check for continuity between
the two heated seat element circuit cavities while
moving the appropriate seat cushion. Refer toWir-
ingfor the location of complete heated seat system
wiring diagrams. There should be continuity. If OK,
the elements within the seat assembly test OK, go to
Step 4. If not OK, replace the faulty seat heating ele-
ment, refer to the procedure in this section.
(4) Test the seat wire harness between the heated
seat module connector and the appropriate heated
seat wire harness connector for shorted or open cir-
cuits. If OK, element is OK, proceed with testing the
heated seat sensor and module. If not OK, repair the
shorted or open seat wire harness as required.
REMOVAL
Do not remove the heating element from the seat
or seat back cushion. The original element is perma-
nently attached to the seat cushions and cannot be
removed without damaging the cushion. The replace-
ment heating element is designed to be applied
directly over the original seat heating element.
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the appropriate seat cushion or seat
back trim cover. Refer to the Body section of this
manual for the procedures.
(3) Disconnect the inoperative heated seat cushion
or seat back element electrical connectors.
(4) Locate the wires leading from the inoperative
heating element and cut them off flush with the edge
of the original heating element.
INSTALLATION
(1) Peel off the adhesive backing on the back of the
replacement heating element and stick directly over
the original heating element (Fig. 3).
CAUTION: During the installation of the replace-
ment heating element, be careful not to fold or
crease the element assembly. Folds or creases will
cause premature failure.
(2) Connect the new heating element electrical
connectors (Fig. 2).
(3) Connect the battery negative cable.
(4) Verify heated seat system operation.

CYLINDER-TO-CYLINDER LEAKAGE TEST
To determine if an engine cylinder head gasket is
leaking between adjacent cylinders, follow the proce-
dures in Cylinder Compression Pressure Test in this
section. An engine cylinder head gasket leaking
between adjacent cylinders will result in approxi-
mately a 50±70% reduction in compression pressure.
CYLINDER-TO-WATER JACKET LEAKAGE TEST
WARNING: USE EXTREME CAUTION WHEN THE
