Check your memory wire, and make sure it has a constant voltage on it. Should be the yellow wire.

F6E1 - SERIAL COMMUNICATION ERROR

The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.

Possible Causes/Procedure

- Unplug washer or disconnect power.
- Check that the power cord terminals are connected at the right position to the RFI filter (white-Neutral/ black-Line).
- Check that the two ground switches are pressed correctly by the toe and rear panels.
- Check that ground switches are fitted correctly, and are not broken and the green ground wires are connected correctly.
- Make sure that both ground switches are not broken or scratched.
- Make sure that all the ground harnesses (green wires) are connected correctly, and are not broken or with wires detached.
- Make sure that all wire harness connections from the CCU (MI3 cavity), main Motor, and MCU are not broken or with wires detached, and that connector internal pins are visible.
- Check for continuity from the MCU connector wires to CCU (MI3 cavity) connector.
- If the continuity diagnosis failed, the Main Harness must be replaced.
- Make sure that all the connectors are fully seated.
- Check the drive system for any worn or failed components.
- Plug in washer or reconnect power.
- Verify the washer operation by running the Diagnostic Test cycle. See page 5.
- After the diagnostic test has finished, unplug washer or disconnect power and wait for 15 seconds.

FH-P8000bt will not power up


Check the fuses. One in the fuse panel in the car and one on the back of the head unit. If one of those is the problem, just replace it and you should be good. If not, check that the power wire is securely connected between the wiring harness and head unit, then make sure the ground wire is firmly fastened to the sub dash in an area with bare metal, free of paint and dust, dirt, rust, etc. If none of this helps, the unit may very well be fried....

How to install KDC-252U in a 2000 Toyota Tacoma two-door


Check the fuse box in the engine compartment and look for the interior illumination fuse. Before you replace it you will need to unplug the radio harness and check the new unit's memory lead, the switched 12 volt lead, and the Ground wire. Somewhere one or two of these have been either connected incorrectly or the wires were pinched when the dash was reassembled.


Also check the fuse in the new unit's harness and make sure it is ok. Here are the basic power wires in the Tacoma...yellow is 12v constant, red is accessory (turns on with key),and black is ground.
If there is a blue wire, it needs 12 volts when the car is running and the radio is turned on. Check your new unit's wiring diagram for the power antenna or amplifier turn-on lead and connect that to the blue wire.
Good luck

I have a bv7320 head unit i am trying to install into my ford ranger. i have all of the wires matched up and im not getting any power to the unit. i have a amp powering all my speakers and a seperate one...


Since you did not mention the year of the vehicle, I cannot be sure of the power/ground connection. However, if you are sure of the connections, let us proceed. Check the constant 12 volt for power. Check the accessory power connection for 12 volts when the key is on. Check the ground connection for a good chassis ground. If you do not have power at these connections, check your fuses at the vehicle fuse box and at the stereo head unit itself (if one exists). If all power and ground connection are good and all fuses are good and, your unit still does not power on, check and make sure that the pins in the stereo harness are properly seated.
If all of these things check out as good then the issue is with the head unit.

Hello, the name's Jordan The Product: Pioneer Avid D3 Navigation system. Here's my problem: The screen will not come on. I have already attempted to hit the reset button, and still nothing. My...


Sounds like a power issue. If you don't have power on both the constant and the switched ignition wires for the head unit you'll usually end up getting the little LED light on the unit so it looks like it should be working ok but the screen won't turn on and the unit won't work. If you can take the head unit out yourself and access the wires behind it then here's a simple walk thru that you can use to pin point the issue.

First things first, before taking the time to remove the head unit, check your fuses in the car fuse block. If your fuse box cover doesn't give a description for each fuse, then look in the owner's manual for the car. (flip to the very back index under "F" and it will have a page number for "fuses". The first one to check will be the Radio fuse. If this one is ok, then also look at the following:
Accessory, cig lighter, instrument cluster, interior lights/domelights, audio, and amplifier. Not all cars have the same fuses and names, so just look thru the descriptions carefully and use your best judgement. In some vehicles the radio actually shares a power circuit with the things I just listed above, even though you wouldn't think it makes much sense. Also, keep in mind that most cars have multiple fuse box locations so if you don't see it on the interior fuse box, be sure to check the underhood fuse box too. Some cars will have a fuse box under the driver's side dash, another on the passenger side, another under the hood, and some cars even have them in the trunk or under the back seat.

If all these fuses check out ok then you'll need to dig a little deeper. Here's where you'll need to pull the head unit out of the dash and access the wiring. If you unplug the main radio harness from the back of the Pioneer you'll notice that there's a fuse here as well. They're usually a red, 10 amp mini ATC fuse. If this fuse is ok then continue on.

In order for a radio to turn on and work you need to have 3 wires connected properly. With just these 3 the unit will turn on and act just the way it should but you wouldn't hear any sound without the speaker wires being connected etc.

The 3 main wires are Power (aka 12+ or battery), Switched Ignition, and Ground. The Power wire is YELLOW and is considered a constant power wire. This feeds just enough power to the radio at all times to retain audio settings, radio channel favorites/presets, the clock and so on without killing your car battery.

Switched ignition is the RED and this wire only provides power when the key is turned on. Technically you can wire both the red and yellow wire to ignition only or constant/battery only but then every time you turned the car off you'd have to set all your favorites again, redo your audio settings and reset your clock OR if you wired them both up to constant instead your radio would stay on even when you turn the key off and you'd come out to dead battery every morning.

The ground wire is BLACK. This should be either connected to a ground wire in the radio harness, or if the specific car side radio harness doesn't have a ground wire, you could also connect this wire straight to metal inside the car.

If all the fuses are still good in the car using a voltmeter or multi-meter with a voltage setting and put the black terminal lead on the BLACK ground wire and the other terminal lead (usually red) on the YELLOW constant wire first. With the key turned off you should see anywhere from about 11 to about 13 volts. If you do, that's good. If not, you have a fuse blown somewhere in the car or a bad connection on this wire between the car harness and your radio harness.

Now, keeping the black lead on the ground wire, put the other lead on the RED Switched Ignition wire. With the key turned off thise should read at 0 volts, now turn the key on and you should get again somewhere between 11 and 13 volts. If you don't have power in this wire with the key turned on then again you have a blown fuse somewhere that you missed or a bad connection between the car and radio.

IF you didn't get any power on EITHER wire with either the key on OR off then you probably have a
bad ground connection. Put the black lead from your meter onto bare metal and repeat the last steps with the YELLOW and RED wires. If you get voltage now like you should have in the above steps then you know you have a bad ground connection between the car and the radio. Double check the ground connection or just attach the black wire from the Pioneer directly to bare metal in the car. Good luck

My kEnmore front load he2 plus washer is flashing f-28 does anyone know what this means?


Hi,

F-28 refers to Communication Error.

Possible Causes/Procedure

1. Unplug washer or disconnect power.

2. Check wire harness connections to the MCU, the motor, and

Central Control Unit (CCU).

- Check connections of the CCU board within the housing.

- Make sure all grounding switches are engaged.

3. Check the drive system for any worn or failed components.

4. Plug in washer or reconnect power.

5. Verify CCU operation by running a Diagnostic Test
or any

cycle.

6. Check the MCU by looking for operations of the drive motor.

7. Check the drive motor for powered rotations.

8. Check that the serial harness at the MCU is not mounted

upside down. The wires should be to the left when facing

the MCU connectors.

Note - The cost of CCU and MCU is more than $200 each. You cannot replace a part of CCU and MCU. The complete Set needs to be changed. If the Washer is more than 4 years ( which i assume, as this Error is usually after 4-5 Years ), it is better to Invest in new one than Repair.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Sound went completely dead on an 07 Crown Victoria. I checked all the fuses and all are good...plugged the original deck back in and still no sound...nothing..completely dead..all connections look good...


Be sure you checked all 3 fuses, F3 5amp, F9 7.5amp. F12 15amp. Test with test light the red and black wire in start, the dark blue and light green in accesory, and the violet hot at all times. These are all in the harness to the radio. Then test grounds by clamping the test light to battery positive, and check the black wire and the two black and light greens. If both units are good, there's gotta be a bad power or ground.

hi there
if you matched all the wires from the harness to the kenwood deck and its not working don't worry you just missed the last step........(all wires attached that a colour coded connected)
simply turn your car on.........now on the front of the kenwood deck there is a SOURCE button with all units it could be a (S, SRC, Power) hold the source button down till your kenwood unit powers up ..........if your unit still doesn't work check the fuse on back of kenwood unit should be a 10a fuse (blue) if the fuse is fine put the unit back in dash..........now check the fuse panel on driver side dash with the door open you will see this panel pull it off (some describe the fuse panel as looking like an air vent but its not its a handle to open) now on the panel that you just pulled off there is a fuse diagram on the inside look at it find radio fuse it will be a (blue fuse) located in the top row of fuses check it if blown replace and unit should work.............if this doesn't solve the issue than its a (sneaky) fuse not to many people know about if you pop the hood of your car there is a black plastic panel located just below the battery pins and just above the driver head light (usually black box with yellow writing on it......in this there are mini fuses check all of them do not touch the black relays in there just the small tiny fuses the fuse you will look at should be yellow 20a (this fuse is closest to engine and comes after the abs relay if you look inside the lid you took off it will have fuse locations cant remember which one it is for sure but check them..........now see if your kenwood unit powers up if not the last option is to ground to the black wire from back of kenwood unit to metal frame.............this last part is also done if your unit does power on but your car lights don't work if this happens ground the kenwood unit to the frame of car and open up fuse panel on driver side dash replace the blown fuse for lights or radio (make sure the kenwood unit is grounded to the frame before replacing the fuse in dash panel............if this doesnt help you than i would assume the kenwood deck needs to be repaired by kenwood.......
good luck
hope i was able to help and sorry this list is so long
