RAIL - FUEL
DESCRIPTION
The fuel injector rail is used to mount the fuel injectors to the engine.
OPERATION
High pressure from the fuel pump is routed to the fuel rail. The fuel rail then supplies the necessary fuel to each
individual fuel injector.
A quick-connect fitting with a safety latch clip is used to attach the fuel linetothefuelrail.
The fuel rail is not repairable.
CAUTION: The left and right sections of the fuel rail are connected with either a flexible connecting hose, or
joints. Do not attempt to separate the rail halves at these connecting hoseor joints. Due to the design of
the connecting hose or joint, it does not use any clamps. Never attempt to install a clamping device of any
kind to the hose or joint. When removing the fuel rail assembly for any reason, be careful not to bend or
kink the connecting hose or joint.

RELAY - FUEL PUMP
DESCRIPTION
The 5–pin, 12–volt, fuel pump relay is located in the Power Distribution Center (PDC). Refer to the label on the PDC
cover for relay location.
OPERATION
The Powertrain Control Module (PCM) energizes the electric fuel pump through the fuel pump relay. The fuel pump
relay is energized by first applying battery voltage to it when the ignition key is turned ON, and then applying a
ground signal to the relay from the PCM.
Whenever the ignition key is turned ON, the electric fuel pump will operate. But, the PCM will shut-down the ground
circuit to the fuel pump relay in approximately 1–3 seconds unless the engine is operating or the starter motor is
engaged.
REMOVAL
The fuel pump relay is located in the Power Distribu-
tion Center (PDC) (2). Refer to label on PDC cover for
relay location.
1. Remove PDC cover.
2. Remove relay from PDC.
3. Check condition of relay terminals and PDC con-
nector terminals for damage or corrosion. Repair if
necessary before installing relay.
4. Check for pin height (pin height should be the
same for all terminals within the PDC connector).
Repair if necessary before installing relay.
INSTALLATION
The fuel pump relay is located in the Power Distribution Center (PDC). Refer to label on PDC cover for relay loca-
tion.
1. Install relay to PDC.
2. Install cover to PDC.

DIAGNOSIS AND TESTING
WAT E R L E A K S
Water leaks can be caused by poor sealing, improper body component alignment, body seam porosity, missing
plugs, or blocked drain holes. Centrifugal and gravitational force can cause water to drip from a location away from
the actual leak point, making leak detection difficult. All body sealing points should be water tight in normal wet-
driving conditions. Water flowing downward from the front of the vehicle should not enter the passenger or luggage
compartment. Moving sealing surfaces will not always seal water tight under all conditions. At times, side glass or
door seals will allow water to enter the passenger compartment during highpressure washing or hard driving rain
(severe) conditions. Overcompensating on door or glass adjustments to stop a water leak that occurs under severe
conditions can cause premature sealwear and excessive closing or latching effort. After completing a repair, water
test vehicle to verify leak has stopped before returning vehicle to use.
VISUAL INSPECTION BEFORE WATER LEAK TESTS
Verify that floor and body plugs are in place, body drains are clear, and body components are properly aligned and
sealed. If component alignment or sealing is necessary, refer to the appropriate section of this group for proper
procedures.
WATER LEAK TESTS
WARNING: Do not use electric shop lights or tools in water test area. Personal injury can result.
When the conditions causing a water leak have been determined, simulate the conditions as closely as possible.
Ifaleakoccurswiththevehicleparkedinasteadylightrain,floodtheleak area with an open-ended garden
hose.
If a leak occurs while driving at highway speeds in a steady rain, test the leak area with a reasonable velocity
stream or fan spray of water. Direct the spray in a direction comparable to actual conditions.
If a leak occurs when the vehicle is parked on an incline, hoist the end or sideofthevehicletosimulatethis
condition. This method can be used when the leak occurs when the vehicle accelerates, stops or turns. If the
leak occurs on acceleration, hoist the front of the vehicle. If the leak occurs when braking, hoist the back of the

vehicle. If the leak occurs on left turns, hoist the left side of the vehicle. If the leak occurs on right turns, hoist
the right side of the vehicle. For hoisting recommendations (Refer to LUBRICATION & MAINTENANCE/HOIST-
ING - STANDARD PROCEDURE).
WATER LEAK DETECTION
To detect a water leak point-of-entry, do a water test and watch for water tracks or droplets forming on the inside of
the vehicle. If necessary, remove interior trim covers or panels to gain visual access to the leak area. If the hose
cannot be positioned without being held, have someone help do the water test.
Some water leaks must be tested for a considerable length of time to become apparent. When a leak appears, find
the highest point of the water track or drop. The highest point usually willshow the point of entry. After leak point
has been found, repair the leak and water test to verify that the leak has stopped.
Locating the entry point of water that is leaking into a cavity between panels can be difficult. The trapped water may
splash or run from the cavity, often at adistance from the entry point. Mostwater leaks of this type become appar-
ent after accelerating, stopping, turning, or when on an incline.
MIRROR INSPECTION METHOD
When a leak point area is visually obstructed, use a suitable mirror to gainvisual access. A mirror can also be used
to deflect light to a limited-access area to assist in locating a leak point.
BRIGHT LIGHT LEAK TEST METHOD
Some water leaks in the luggage compartment can be detected without water testing. Position the vehicle in a
brightly lit area. From inside the darkened luggage compartment inspect around seals and body seams. If neces-
sary, have a helper direct a drop light over the suspected leak areas aroundthe luggage compartment. If light is
visible through a normally sealed location, water could enter through theopening.
PRESSURIZED LEAK TEST METHOD
When a water leak into the passenger compartment cannot be detected by water testing, pressurize the passenger
compartment and soap test exterior ofthe vehicle. To pressurize the passenger compartment, close all doors and
windows, start engine, and set heater control to high blower in HEAT position. If engine can not be started, connect
a charger to the battery to ensure adequate voltage to the blower. With interior pressurized, apply dish detergent
solution to suspected leak area on the exterior of the vehicle. Apply detergent solution with spray device or soft
bristle brush. If soap bubbles occur at a body seam, joint, seal or gasket, the leak entry point could be at that
location.
WIND NOISE
Wind noise is the result of most air leaks. Air leaks can be caused by poor sealing, improper body component
alignment, body seam porosity, or missing plugs in the engine compartmentor door hinge pillar areas. All body
sealing points should be airtight in normal driving conditions. Moving sealing surfaces will not always seal airtight
under all conditions. At times, side glass or door seals will allow wind noise to be noticed in the passenger com-
partment during high cross winds. Over compensating on door or glass adjustments to stop wind noise that occurs
under severe conditions can cause premature seal wear and excessive closing or latching effort. After a repair pro-
cedure has been performed, test vehicle to verify noise has stopped beforereturning vehicle to use.
VISUAL INSPECTION BEFORE TESTS
Verify that floor and body plugs are in place and body components are aligned and sealed. If component alignment
or sealing is necessary, refer to the appropriate section of this group forproper procedures.
ROAD TESTING WIND NOISE
1. Drive the vehicle to verify the general location of the wind noise.
2. Apply 50 mm (2 in.) masking tape in 150 mm (6 in.) lengths along weatherstrips, weld seams or moldings. After
each length is applied, drive the vehicle. If noise goes away after a piece of tape is applied, remove tape, locate,
and repair defect.

The motor/module is programmed to learn the speed required to drive the panel based on position and recalibrates
itself as needed. If the sunroof becomes uncalibrated, it will only respond to the vent switch. If the vent switch is
pressed, the glass will move toward vent; if the switch is released, all motion stops. In the event that the sunroof
system becomes uncalibrated performthe sunroof position calibration procedure, (Refer to 8 - ELECTRICAL/
POWER TOP/MOTOR - STANDARD PROCEDURE -SUNROOF POSITION CALIBRATION).
DIAGNOSIS AND TESTING
POWER TOP - SUNROOF
Any diagnosis of the power sunroof system should begin with the use of a scantool and the proper Diagnostic
Procedures Information. The scan tool can provide confirmation that the Controller Area Network (CAN) Data Bus is
functional, that all of the electronic modules are sending and receiving the proper messages on the CAN Data Bus,
and that the power sunroof motor is being sent the proper hard wired output by the sunroof switch.
For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out
information and location views for the various wire harness connectors, splices and grounds.
Refer to the appropriate diagnostic information.
SUNROOF
Refer to SUNROOF DIAGNOSIS CHART for possible causes. Before beginning sunroof diagnostics verify that all
other power accessories are in proper operating condition. If not, a common electrical problem may exist. Refer to
Wiring Diagrams, in this publication for circuit, splice and component descriptions. Check the condition of the circuit
protection (20 amp circuit breaker in the Junction Block). Inspect all wiring connector pins for proper engagement
and continuity. Check for battery voltage at the power sunroof controller, refer to Wiring Diagrams, for circuit infor-
mation. If battery voltage of more than 10 volts is detected at the controller, proceed with the following tests (the
controller will not operate at less than 10 volts).
Before beginning diagnosis for wind noise or water leaks, verify that the problem was not caused by releasing the
control switch before the sunroof was fully closed. The sunroof module hasa water-management system. If how-
ever, the sunroof glass is in a partial closed position, high pressure water may be forced beyond the water man-
agement system boundariesand onto the headlining.
Every time the sunroof module loses power it must be initialized. This is done by connecting power to the sunroof
and moving the sunroof toward the closed position. When initialization occurs a slight “kick” in the sunroof module
will be seen and heard. This is the indication that the sunroof module is initialized
