2003 FORD MUSTANG oil

DIAGNOSIS AND TESTING
Convertible Top
Refer to Wiring Diagrams Cell
103 , for schematic and connector information.
Principles of Operation
The convertible top will only operate with the parking brake engaged and the ignition switch in the RUN
position. When the parking brake is engaged, the raise and lower relay coils are grounded through the
parking brake switch. The convertible top switch supplies power to the raise or lower relay coil when
raise or lower is selected. This power energizes the coil causing the relay contacts to close which
supplies battery power to the convertible top motor/pump assembly. The normal state of the relay is
connected to ground. When the raise or lower relay is operating, the other relay remains in its normal
state supplying the motor/pump ground.
Convertible Top Adjustments
The convertible top adjustments must be made by a qualified technician.
Inspection and Verification 1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the concern is not visually evident, verify the symptom and refer to the Symptom Chart.

REMOVAL AND INSTALLATION
Rear Subframe
Removal and Installation
CAUTION: Suspension fasteners are critical parts because they affect performance of vital
components and systems and their failure can result in major service expense. A new part with
the same part number must be installed if installation becomes necessary. Torque values must
be used as specified during reassembly.
1. Remove the rear coil springs. For additional information, refer to Section 204 - 02 .
2. Using the special tool, raise the rear subframe.
3. Remove and discard the rear subframe front bolts.
4. Using the special tool, lower and remove the rear subframe.
5. NOTE: Discard the old bolts and nuts. Do not reuse, install new bolts and nuts.
To install, reverse the removal procedure.
