Power Folding Top System Components
The power folding top system consists of the following components:
• Folding top control (FTC) module
• Body control module (BCM)
• Folding top control switch
• Serial data communication
• Folding top cover latch actuator
• Folding top cover pull down actuator
• Folding top pump motor with valve manifold
• Position switches and limit switches:
- Pin receiver switch
- Luggage barrier switch
- Folding top cover open switch
- Top open switch
- Top closed switch
- 5 bow raised switch
- 5 bow lowered switch
• Tonneau release relay
• TONNEAU PULL DOWN ACTUATOR Fuse 20 A
• TONNEAU RELEASE Fuse 10 A
• BATT 2 Fuse 40 A
• REAR FOG/ALDL TOP SW Fuse 10 A
• Folding top mechanical components:
- Folding top
- Folding top cover
- Folding top valve 1
- Folding top valve 2
- Folding top valve 3
- Hydraulic lines and cylinders

Folding Top Cover Latch Actuator
The power folding top system includes a folding top cover that is powered open and close by a hydraulic system that is controlled by the FTC module. A power unlatch motor is used to unlatch the folding top cover before the folding top control (FTC) module powers the top cover open. The folding top cover unlatching is requested by the FTC module via class 2 message, but is executed by the body control module (BCM). When requested, the BCM applies battery voltage through the folding top cover release relay control circuit to the tonneau release relay. The relay is energized and battery voltage is applied through the folding top cover release control circuit to the latch actuator. The actuator is energized and the latch releases the folding top cover.

The electronics on this are very complex ,

System Operation
Before any movement of the power folding top is allowed, the folding top control (FTC) module must be aware of the following conditions:
• Unlatch the header. The FTC module reads the pin receiver switch is Inactive.
• The windows must be normalized. Refer to Power Window Reinitialization.
• The ignition must be placed in Accessory or RUN.
• The transmission must be placed in PARK, or with manual transmission, the park brake must be applied.
• Trunk status must not be ajar.
• The luggage barrier must be in place.
• The pump motor temperature must be within the operating range.

After the last cycle of power folding top operation, allow the hydraulic system a minimum of 4 minutes to bleed down before attempting manual operation of the top.
Your best bet take and have it checked for DTC'S - diagnostic trouble codes .

FIRST, unplug the washer and thoroughly check the power cord for breaks. Secondly, if no obvious signs of a break or bad plug are found, HAVE A QUALIFIED ELECTRICIAN OR TECH check the AC outlet for a broken ground wire! If the ac outlet is good, then remove the front panel by using a 2 inch putty knife, sliding it between the top cover and the front cover approx 2 inches from both sides and pushing in firmly to release the retaining clips. Pull the front cover out from the top and then off of the positioning tabs at the bottom. If you are hesitant about doing any of this, call for service! These washers leak from the central tub seal at the bottom. Water can leak down the steel shaft straight into the electric shifter. Also, if the leak is bad enough, the water can be thrown into the main drive motor(which has the main control board mounted on top of it)and cause all sorts of problems. If your unit has a tub seal leak, it is a MAJOR repair, requiring the shifter to be replaced, if water has gotten into the motor, it, too, will have to be replaced.

The compressor has three terminals, Common, Start and Run.... The terminals read left to right, top to bottom just like pages in a book. So if theres one on top, its Common then Start will be the first one in the next row. If theres two on top, it'll be Common on the left and Start on the right then Run on the bottom.

The run capacitor wires in between Start and Run and line voltage is applied to Common and Run.

Hi,

Here are a couple of tips that I wrote that tell you how to troubleshoot a Torpedo or Reddy heater...

Torpedo Heater Pump Pressure Adjustment

/..................

Open the pump bypass valve for the top to manually open/close top. Bypass valve is located in trunk on left; remove round 2" cover and turn the exposed valve anti-clockwise.
Problem of motor not moving top is likely low on pump oil. Remove cover on left in trunk and refill slowly after removing the fill plug on top of pump. Use 10w30 oil.

Your problem could be one of 2 things either the base is pushed up in the center or the front apron is bent. The apron is the piece of metal that runs across under the top cover. To remove the front cover to see either use a putty knife to release the catch between the top and the front cover and pull front outward one side at a time.

There's more then one fan inside the projector. I think I counted 3 when I opened mine up. Two are easy to get to, the other is underneath. on theleft side looking from the front. You have to take off the back surround cover in onder to remove the top cover. The top cover slides back and lifts up. Be careful because there's a wire harness running to the top cover control panel. Disconnect it then you have access to the fans. Wish mine was that easy to repair.

trace the high tension wire that runs from the distributor. the other end should be attached to the spark plugs.

It is lickly that when you put the top on that the top is creating a ground (completing the circuit) which means there is no spark created

Your ignition coil is cracked. Replace it with a new OEM unit.
