(1) Check the fused B(+) fuse in the Integrated
Power Module (IPM). If OK, go to Step 2. If not OK,
repair the shorted circuit or component as required
and replace the faulty fuse.
(2) Check for battery voltage at the fused B(+) fuse
in the IPM. If OK, go to Step 3. If not OK, repair the
open fused B(+) circuit to the IPM fuse as required.
(3)
Open the power outlet door. Check for continuity
between the inside circumference of the power outlet
receptacle and a good ground. There should be continu-
ity. If OK, go to Step 4. If not OK, go to Step 5.
(4) Check for battery voltage at the insulated con-
tact located at the back of the power outlet recepta-
cle. If not OK, go to Step 5.
(5) Disconnect and isolate the battery negative
cable. Remove the appropriate bezel. Check for conti-
nuity between the ground circuit cavity of the power
outlet wire harness connector and a good ground.
There should be continuity. If OK, go to Step 6. If not
OK, repair the open ground circuit to ground as
required.
(6) Connect the battery negative cable. Check for
battery voltage at the fused B(+) circuit cavity of the
power outlet wire harness connector. If OK, replace
the faulty power outlet receptacle. If not OK, repair
the open fused B(+) circuit to the IPM fuse as
required.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Look inside and note position of the retaining
bosses (Fig. 5).
(3) Using external snap ring pliers with 90 degree
tips. Insert pliers with tips against bosses and
squeeze forcing bosses out of base.
(4) Pull out the base through mounting ring by
gently rocking pliers. A tool can be made to do the
same. Refer to (Fig. 6).
(5) Disconnect the base wires.
(6) Set base aside. Remove light ring and discon-
nect wire.
INSTALLATION
(1) Position the mounting ring on the instrument
panel and feed the wires through the ring. Index the
cap and the mounting ring with the index tab at the9 o'clock position to the key in the instrument panel.
Install the ring.
(2) Connect the wires to the base. Orientate the
base alignment rib at the 11 o'clock position to mate
the groove in the mounting ring to the base.
(3) Push the base into the bezel until it locks in
place.
(4) Check operation of outlet or element and
install the 12 volt outlet cap.

ENGINE 2.4L
DESCRIPTION
The 2.4 Liter (148 cu. in.) in-line four cylinder
engine is a double over head camshaft with hydraulic
lash adjusters and four valve per cylinder design.
The engine is free-wheeling; meaning it has provi-
sions for piston-to-valve clearance. However valve-to-
valve interference can occur, if camshafts are rotated
independently.
The cylinders are numbered from front of the
engine to the rear. The firing order is 1±3±4±2.
The engine identification number is located on the
rear of the cylinder block (Fig. 1).
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - ENGINE
DIAGNOSIS - INTRODUCTION
Engine diagnosis is helpful in determining the
causes of malfunctions not detected and remedied by
routine maintenance.
These malfunctions may be classified as either
mechanical (e.g., a strange noise), or performance
(e.g., engine idles rough and stalls).
Refer to the Engine Mechanical and the Engine
Performance diagnostic charts, for possible causes
and corrections of malfunctions (Refer to 9 - ENGINE
- DIAGNOSIS AND TESTING - MECHANICAL)
(Refer to 9 - ENGINE - DIAGNOSIS AND TESTING
- PERFORMANCE).
For fuel system diagnosis, (Refer to 14 - FUEL
SYSTEM/FUEL DELIVERY - DIAGNOSIS AND
TESTING).
Additional tests and diagnostic procedures may be
necessary for specific engine malfunctions that can-
not be isolated with the Service Diagnosis charts.
Information concerning additional tests and diagno-
sis is provided within the following:
²Cylinder Compression Pressure Test
²Cylinder Combustion Pressure Leakage Test
²Engine Cylinder Head Gasket Failure Diagnosis
²Intake Manifold Leakage Diagnosis
²Hydraulic Lash Adjuster Noise Diagnosis
²Engine Oil Leak Inspection
