Well I also lost the little tag plate.
Left indeed is a keyborad lock.
On my FTC-1903 the middel and right toggle switch does not seem to have any effect.

The middel one switches between "busy - manual - ...?..." and the right one between "USA-International". I guess the right one switches to a preset order of channel allocation, different for USA or other countries.

On mine swicthing middel or roght switch does not seem to give any effect.
So I would like to open up the set but would like to do so with the help of a schematic drawing.

Any source to find that?

07 corvette top will retract but deck lid makes no effort to close, then top will not go back up. Need to release pressure in block lift top up about 1/4 of way then top will go back up


Manually Moving the Folding Top from the Down Position
Important: Allow the system a minimum of four minutes to bleed down pressure after the last cycle.
Manually release the folding top cover latch using the emergency release cable.
Raise the folding top stowage cover.
Manually raise the folding top, holding the 5 bow up.
Manually lower and latch the folding top stowage cover.
Manually unfold the top and latch per normal procedure.

Manually Moving the Folding Top from the Up Position
Important: Allow the system a minimum of four minutes to bleed down pressure after the last cycle.
Manually release header latch per normal operation.
Manually lift front of roof off of the header and raise the #5 bow at the same time.
Manually release the Folding Top Cover latch using the emergency release cable.
Fold the roof down into the well.
Manually close and latch the folding top stowage cover.

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 .
DTC B3666 Rear Tonneau Position Error
DTC B3667 Tonneau Release Circuit
DTC B1011
DTC B1291

How do I re-program my Yaesu FTC-1143 to the Ameatur 70m Band


Hi Rick,

If I'm not Wrong, You have the UHF Model radio, and therefore can't program VHF frequencies as it's the wrong band. If I am wrong, then you have a dual band radio, which should be pre-programmed with all the correct frequencies for both 2m & 70cm bands.

I hope this answers your query.

Cheers,
Peter

2001 jeep grand cherokee laredo, lights come one intermittently, horn came on unexpectedly and wouldn't turn off. How do I fix that?


Lights intermittent can be caused by switch or relay. Try swapping the Low Beam relay with another similar relay (horn relay is a good choice) to see if that resolves it. These relays are in the Junction Block--may be under the hood or in the car but not in the big box by the battery). If this doesn't fix it, the problem is likely the headlamp switch.

Horn coming on is usually caused by a broken switch or stripped wire insulation inside the steering column. You would usually have to take the steering wheel off to fix it, and this requires special tools; however, if the problem happens to be under the steering column shroud, you may be able to fix it without taking off the steering wheel. Take the shroud off and see if you can follow the black/red horn wire. Follow it as far as you can to check for stripped insulation contact with any metal. If you lights switch is bad, you can also change that while you have the shroud off.

Please let me know if you have questions.

How do i get the channels to change on vx10 radio selector does not seem to change them radio recently repaired by yaesu and user manual not much help


The dial is probably locked. Look for a little padlock symbol on the display. Check the user manual for Dial or keyboard lock. Generally on Yaesu radios you use the function key plus a keyboard key. If the keyboard is labeled, you should see something that looks like a padlock next to the correct function key.
