SECTION 501-18: Convertible Top
DIAGNOSIS AND TESTING
Convertible Top
Refer to Wiring Diagrams Cell 102, Convertible Top for schematic and connector information.
Special Tool(s)
73 III Automotive Meter
105-R0057 or equivalent
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 Adjustment
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.
