Hi I have a 2006 Lincoln navigator the air suspension pump will not turn on the vehicle dynamics module is not turning on the pump relay because in the pid data the drivers door says it is ajar when it is...


Hey Jeff, any U- codes stored in any modules ?
U1900 Missing CAN message(s) Door(s) ajar, PRNDL, 4x4, instrument cluster (IC), running boards, vehicle speed REFER to Section 418-00 . U2023 Invalid CAN message(s) Door(s) ajar, PRNDL, 4x4, instrument cluster (IC), running boards, vehicle speed REFER to Section 418-00 .
L4 CHECK THE VDM FOR DOOR AJAR INPUT
  • Key in ON position.
  • Monitor VDM door position status PID.
  • Close all doors, liftgate, liftgate glass and power running boards.
  • While observing the diagnostic tool, open and close one door.
  • Does the door status PID change between CLOSED and AJAR states?
When you open an close the driver door you have no PID change ,right ?

  • Does the door status PID change between CLOSED and AJAR states?
The door ajar input is an input to the Vehicle Security Module , then transmitted over the bus ! You'll have to find a diagram for the med. speed CAN data bus .

Nordic Track treadmill A2105 will shut down and trip my HOME breaker while in use, what could be the problem? I have tried lubricating the belt and it worked a little longer than usual, but after abo


1) you must LUBE THE DECK BELT+ ROLLER BEARING.

2) Test the input voltage motor, if there are the MOTOR is faulty need REPAIR.

3) Test the output voltage board, for input voltage motor, if there are NOT the board is faulty.
4) SEE THE BLOCK DIAGRAM, whatever component can be faulty.
However you must test the power cord for short circuit between cable, repair, and look inside according the BLOCK, and proceed with logic, see any loose wires, or some wires touching the carcase, some filter, coil, power supply USE the VOM.
God bless you

Trips breaker and get "PF" on display even when not tripped


This error code indicates "power failure" was detected. This could be caused by a bad/loose connection at either the logic board, the relay board, or at one of the three main power connection terminals on the back of the dryer. The logic board is located inside the control panel. The relay board is located in the base of the dryer. You can unplug and reseat electrical connections at these locations and check the main power cord hook-up at the terminal block. Hope this helped and best wishes.

I have a GE Dishwasher model GSD4430X72WW.


Hi, the surge has fried the logic sector of the control. it will work upon reset until the logic chip is commanded to initiate a wash. thsi is when the fault will kick in. I recommend replacing the control. this is the best action.

Logic alx1280 2 ch amp


Amps can be rated based on their RMS power or their peak power. In this case, the amp's rated RMS power is 300x2 at 2 ohms (total 600W RMS) with a peak power rating of 600x2 (1200W peak). For the most part, peak power means almost nothing.

If your head unit didn't have RCA preamp outputs, you would used the standard speaker outputs from the head unit and connect them to the hi input plug of the amp.

Liftmaster garage door intermittent power loss


I had the same problem. Although it appeared to be the logic board, on mine it actually was the connectors between the logic board and the power supply board.
There are 2 connections on the logic board. One white connector with wires going to the main unit, and another set of connectors that plug directly into the smaller circuit board that holds the step-down transformer (120vac - 22vac). These pins were not making good connection between the boards. I simply bent the pins slightly so they would make better contact on the logic board and have not had a problem since. This must be a weak point on these door openers. Purchasing a new logic board would work too, as the connectors are newer and tighter.
