Chrysler Sebring, Stratus sedan, Sebring Convertible. Manual - part 343

(5) Using a voltmeter, connect the ground lead to

PIN B of the switch harness connector. Connect the
positive lead to PIN A (Fig. 6). If battery voltage is
present, the ground and voltage circuits to the power
seat switch are OK. Check the power seat switch for
proper operation (Refer to 8 - ELECTRICAL/POWER
SEATS/DRIVER SEAT SWITCH - DIAGNOSIS AND
TESTING). If the seat switch checks out OK, remove
the seat assembly and check the circuits from the
power seat switch to the power seat track adjuster
motors for proper continuity. If the circuits appear to
be OK, replace the power seat track and adjuster
motors as an assembly.

REMOVAL

Before the seat track can be removed, the front

seat assembly must be removed from the vehicle.
Refer to the Body section of this manual for the
Front Seat Removal and Installation procedure.

(1) Disconnect and isolate the battery negative

remote cable.

(2) Remove the appropriate front seat from the

vehicle. Once the front seat is removed, lay it on a
clean surface upside down to expose the underside of
the seat assembly.

(3) Remove the seat cushion side shields from the

seat assembly. Refer to the Body section of this man-
ual for the Seat Cushion Side Shield Removal and
Installation procedure.

(4) Disconnect the necessary power seat electrical

connectors.

(5) Remove the bolts retaining the power seat

track to the seat assembly and remove.

INSTALLATION

(1) Position the seat track and install the retaining

bolts. Torque the bolts to 12 N·m (108 in. lbs.).

(2) Connect the necessary power seat electrical

connectors.

(3) Install the seat cushion side shields on the seat

assembly. Refer to the Body section of this manual
for the Seat Cushion Side Shield Installation proce-
dure.

(4) Install the appropriate front seat in the vehicle.

POWER TOP - CONVERTIBLE

DESCRIPTION

The power top system allows the convertible top to

be raised and lowered electrically by actuating a
switch in the center floor console. The power top sys-
tem receives battery feed through a fuse in the
Power Distribution Center (PDC), only when the
ignition switch is in the ON position.

The operation of the power top is controlled by the

Body Control Module (BCM). The BCM also controls
the “top down/4 window down feature when the
power top switch is pressed to the second detent posi-
tion.

The main components of the power top system

(Fig. 1) are:

• The power top framework and bows

• The motor/hydraulic pump assembly

• The power top well

• The power top relay assembly

• The power top pivot bracket

• The latch system

• The window regulator modules
The power top motor is part of the motor/hydraulic

pump assembly and cannot be serviced separately. If
the motor is inoperative the complete assembly must
be replaced, (Refer to 23 - BODY/CONVERTIBLE
TOP/HYDRAULIC PUMP MOTOR - REMOVAL).

OPERATION

The power top switch is hard wired to the Body

power top relay control circuit which in turn will
operate the power top motor. If the power top switch
is pressed and held to the down position second
detent, the BCM will command the window drop
relay assembly to drop all windows to the fully down
position.

The power top switch (convertible vehicles only)

has three distinct functions:

• Top Down - This is the first detent on the down

side of the switch. Holding the switch in this position
will lower the top only.

• Top Down/4 window down - This is the sec-

ond detent on the switch. Holding the switch in this
position lowers the convertible top and all 4 windows
down simultaneously only if held in this position.

• Top Up - Holding the switch in this position

raises the convertible top to the closed position. It
will also lower all 4 windows approximately 3 inches
to prevent seal damage. The windows must then be
raised to the full up position by the vehicle operator.

DIAGNOSIS AND TESTING

POWER TOP - CONVERTIBLE

NOTE: The convertible top will raise slowly or make
abnormal noise if the hydraulic fluid level is low.
Always ensure the hydraulic fluid level is within
specifications prior to component replacement.

For complete circuit diagrams, refer to the

appropriate wiring information. The wiring infor-
mation includes wiring diagrams, 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 con-
nectors, splices and grounds.

Any diagnosis of the power top system should

begin with the use of a scan tool and the proper
Diagnostic Procedures Information. The scan tool can
provide confirmation that the Programmable Com-
munications Interface (PCI) data bus is functional,
that all of the electronic modules are sending and
receiving the proper messages on the PCI data bus,
and that the power top motor is being sent the
proper hard wired output by the Body Control Mod-
ule (BCM). Refer to the appropriate diagnostic
information and address any Diagnostic Trou-
ble Codes (DTCs) stored in the BCM.

If no DTCs are stored and the power top is com-

pletely inoperative perform the following diagnostic
steps.

(1) Check the B+ 40 amp fuse in the Power Distri-

bution Center (PDC). If OK, go to Step 2. If not OK,
repair the shorted circuit or component as required
and replace the inoperative fuse.

(2) Remove the rear seat cushion, (Refer to 23 -

BODY/SEATS/SEAT CUSHION - REMOVAL).

(3) Remove the rear seat back, (Refer to 23 -

BODY/SEATS/REAR SEAT BACK - REMOVAL).

(4) Disconnect the motor/hydraulic pump assembly

two wire electrical connector. Place a twelve volt test
light between the terminals in the harness side con-
nector. With the ignition switch in the “RUN” posi-
tion operate the power top switch in both directions.
The test light should light in both directions. If OK,
replace the inoperative motor/hydraulic pump assem-
bly, (Refer to 23 - BODY/CONVERTIBLE TOP/HY-
DRAULIC PUMP MOTOR - REMOVAL). If not OK,
go to Step 5.

(5) Disconnect the power top relay assembly. With

the ignition switch in the “RUN” position check for
Battery voltage at the B+ terminal of the harness
connector. If OK , go to Step 6. If not OK repair the
open B+ circuit as necessary.

(6) Using an ohmmeter test for continuity between

the harness connector ground circuit and a known
good ground. Continuity should be present. If OK go
to Step 7. If not OK, repair the open ground circuit
as necessary.

(7) Place a twelve volt test light between the fused

B+ and power top “UP” relay control terminals in the
harness side connector. With the ignition switch in
the “RUN” position operate the power top switch in
the “UP” direction. Place a twelve volt test light
between the fused B+ and power top “DOWN” relay
control terminals in the harness side connector. With
the ignition switch in the “RUN” position operate the
power top switch in the “DOWN” direction. The test
light should light in both directions. If OK, replace
the inoperative power top relay. If not OK, go to Step
8.

(8) Turn the ignition switch to the “OFF” position.

Disconnect the BCM. Using an ohmmeter check for
continuity on the power top UP and DOWN circuits
between the BCM and power top relay assembly.
Continuity should be present. If OK replace the inop-
erative BCM. If not OK, repair the control circuits as
necessary.

SWITCH - POWER TOP

DESCRIPTION

The power top switch is located in the in the center

floor console.

The switch has three distinct functions:
• Top Down - This is the first detent on the down

side of the switch. Holding the switch in this position
will lower the top only.

• Top Down/4 window down - This is the sec-

ond detent on the switch. Holding the switch in this
position lowers the convertible top and all 4 windows
down simultaneously only if held in this position.

• Top Up - Holding the switch in this position

The power top switch cannot be adjusted or

repaired. If the switch is damaged or inoperative it
must be replaced, (Refer to 8 - ELECTRICAL/
POWER TOP/SWITCH - REMOVAL).

OPERATION

The power top switch is hard wired to the Body

Control Module (BCM) through the Power Top
Switch Mux circuit. The BCM supplies a multiplexed
voltage of approximately 90% of ignition voltage to
the power top switch. Through a series of resistors
the power top switch switches the circuit to ground.
The circuit resistance is varied depending on the
switch position. When a top operation input is
received by the BCM, it will ground the respective
power top relay control circuit which in turn will
operate the power top motor. If the power top switch
is pressed and held to the down position second
detent, the BCM will command the window drop
relay assembly to drop all windows to the fully down
position.
