fails to operate in more than one direction, perform
the following tests. For complete circuit diagrams,
refer toPower Seatin Wiring Diagrams.
(1) Check the power seat circuit breaker under the
seat. If OK, go to Step 2. If not OK, replace the
faulty power seat circuit breaker.
(2) Check for battery voltage at the power seat cir-
cuit breaker under the seat. If OK, go to Step 3. If
not OK, repair the open fused B(+) circuit to the fuse
in the Intelligent Power Module as required.
(3) Remove the outboard seat cushion side shield
from the seat. Disconnect the seat wire harness con-
nector from the power seat switch connector recepta-
cle. Check for battery voltage at the fused B(+)
circuit cavity of the power seat wire harness connec-
tor for the power seat switch. If OK, go to Step 4. If
not OK, repair the open fused B(+) circuit to the
power seat circuit breaker under the seat as
required.
(4) Check for continuity between the ground cir-
cuit cavity of the power seat wire harness connector
for the power seat switch and a good ground. There
should be continuity. If OK, go to Step 5. If not OK,
repair the open ground circuit to ground as required.
(5) Test the power seat switch. Refer toPower
Seat Switchin the Diagnosis and Testing section of
this group. If the switch tests OK, test the circuits of
the power seat wire harness between the inoperative
power seat track adjuster motor and the power seat
switch for shorts or opens. If the circuits check OK,
replace the faulty power seat track unit. If the cir-
cuits are not OK, repair the power seat wire harness
as required.
REMOVAL
WARNING: SOME VEHICLES ARE EQUIPPED WITH
SEATBACK MOUNTED AIRBAGS. BEFORE
ATTEMPTING TO DIAGNOSE OR SERVICE ANY
SEAT OR POWER SEAT SYSTEM COMPONENT
YOU MUST FIRST DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE CABLE. THEN WAIT TWO MIN-
UTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE BEFORE FURTHER SYSTEM SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO DO SO COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.(1) Remove the appropriate seat from the vehicle.
Refer to Body for the procedure.
(2) Remove two seat back mounting bolts and also
remove two seat back recliner bolts (Fig. 10).
(3) Remove four seat track mounting bolts from
cushion pan.
(4) Remove the seat track from seat.
INSTALLATION
(1) Position the seat track and install the retaining
bolts in the seat cushion pan. Torque the bolts to
45-60 N´m.
(2) Install the two seat back mounting bolts.
Torque the bolts to 45-60 N´m.
(3) Install the two seat back recliner bolts. Torque
the bolts to 45-60 N´m.
(4) Install the seat in the vehicle. Refer to the
Body section of the service manual for the procedure.

CYLINDER HEAD
DESCRIPTION
The cross flow designed, aluminum cylinder head
contains dual over-head camshafts with four valves
per cylinder (Fig. 13). The valves are arrange in two
in-line banks. The intake valves face toward the
front of the vehicle. The exhaust valves face the dash
panel. The cylinder head incorporates powdered
metal valve guides and seats. The cylinder head is
sealed to the block using a multi-layer steel head
gasket and retaining bolts.
Integral oil galleries providing lubrication passages
to the hydraulic lash adjusters, camshafts, and valve
mechanisms.
