Have the vehicle speed sensor checked, that is tied in with the speedometer.

If the ECU was faulty, your engine would not run. Check the ODB2 connector is clean.

Manual shift or Four-Wheel Drive Systems - Electronic Shift I'm assuming you have electronic shift because you refer to relay clicking behind the instrument panel . Principles of Operation Transfer Case - Electronic Shift
The four-wheel drive, electronic shift-on-the-fly feature electrically shifts the vehicle transfer case between 2WD, 4X4 HIGH, and 4X4 LOW. The system mode is selected by the operator through the mode select switch (MSS) on the instrument panel. The operator is informed which mode the system is in by two instrument cluster indicators, one for 4X4 HIGH which is 4X4, and one for 4X4 LOW which is LOW RANGE (in 4X4 LOW both the lamps are on). Shifts into 4X4 HIGH can be made at any speed. When shifting into 4X4 HIGH with the vehicle stationary, tooth blockage may occur, preventing shift completion. When the vehicle is driven above 8 km/h (5mph) the shift will complete. When shifting in or out of 4X4 LOW, the generic electronic module (GEM) requires that the vehicle speed be less than 5 km/h (3 mph), the brake pedal be applied, and the transmission in NEUTRAL (automatic transmission) or the clutch pedal be depressed (manual transmission). (The digital transmission range [TR] sensor informs the GEM when the automatic transmission is in the NEUTRAL range position.)
The gearmotor encoder assembly is mounted externally on the transfer case. It drives a rotary cam which moves the mode fork and the range fork within the transfer case between the 4X4 HIGH, 4X4 LOW, and 2WD range positions.
The GEM uses two relays to control the gearmotor encoder assembly shift between 4X4 HIGH, 4X4 LOW, and 2WD modes. The GEM controls the pulse vacuum hublock (PVH) solenoid which supplies engagement and disengagement vacuum to control the hublocks.
The GEM accomplishes shifts by interpreting inputs from:
  • mode select switch (MSS)
  • vehicle speed signal (transmitted from the ABS system)
  • gearmotor encoder plate position
  • brake pedal switch
  • digital transmission range (TR) sensor (automatic transmission)
  • clutch pedal position (CPP) switch (manual transmission)
  • ignition switch
Based on these inputs, the GEM controls the shifts into 2WD, 4X4 HIGH, or 4X4 LOW with the following outputs:
  • low to high relay (clockwise)
  • high to low relay (counterclockwise)
  • pulse vacuum hublock (PVH) solenoid
  • gearmotor encoder assembly
The electronic shift-on-the-fly (ESOF) system has a feature which allows the driver to override the vacuum operated hublocks. When the front hublocks are manually turned to the LOCK position, the hublocks are locked at all times, overriding the vacuum operated system. If the front hublocks are manually turned to the AUTO position, the hublocks can only be locked by turning the MSS to 4X4 HIGH or 4X4 LOW position.

This mirror control switch will pop right out with just a thin blade type screw driver. Slide the blade of the screw driver under the edge of the switch carefully and twist slowly until you can see the switch coming up. You may need to re position the switch as there is a bit of play in the hole the switch fits into to. Once you have the switch up and out of the panel, carefully release the wires it is clipped to and replace it with one that is good. It is a typical sign these witches have gone bad if your mirror only moves in 2 directions or both mirrors are moving at the same time. I hope I have helped you with your problem.

This module should be located inside the cab, drivers side kick panel underneath the dash. The unit should be bolted to the wall directly behind the kick panel on the far left side where you place your feet.

That engine uses high pressure oil to open the injectors. Of course make sure your oil level is up then try turning it over while tapping on the IPC solenoid to see if you have a high pressure oil issue.

ok one thing to do is scan codes to see which sensor is not reading. then go to it with a scanner hooked up. youre gonna be able to see live moh parameters or windows to see live data anyhow access the rear which isnt working. jack up truck safely put in drive then proceed tothe rear sensor wire. u can do this at any sensor that isnt reading. u then look at the mph window in scan tool an watch it while u wiggle the affected sensor wire goin to the harness. watch for jumps an droputs of the mph parameter while wiggling sensor wires from sensor all the way to the harness. thats how its done looking for broken wires. food luck hope this helps

The engines run very lean for fuel efficiency. Although a "cold start sequence" gives the impression of freezing temperatures, the operating range is much higher. The water temperature sensor (some have 2) may be staying too warm for the reset. You may need to change the sensor. Then the fuel mix will be richer and the engine will start.

its on the intake area where the heater gets it air flow. in the shuttle area in engine bay under window.

Why ? If you don't know you don't need to know . Take it to a qualified FORD dealer .

2000 Ford F250... | Answered on Apr 11, 2017


possibly the fuel pump check the fuel pressure with a gauge on the fuel rail if its a gas motor, is it diesel if so your in luck cause im a diesel mechanic

2000 Ford F250... | Answered on Mar 11, 2017


the items that cause changes in the air/fuel mixture are
Heated oxygen sensor( in the exhaust manifolds before the cat converters
Map sensor
Baro sensor
Maf/vaf sensors
intake leaks ( vent on canister , vacuum hoses etc )
failed cat converter blocking exhaust system
The first place I would look at is the heated oxygen sensor(HO2S) as it has rather delicate wires that regularly fail and that causes erratic messages to the ECM

Well you missed something .Let me ask you this what wasn't working before you replaced the multifunction switch.
The brake lights if the blinkers the running lights the head lights int lights all work must be the contact point or switch at the brake padal or a ground issue to the bulbs or the bulbs are incorrect Ford has this issue with the bulbs they look the same but there not check that for the brake lights .
I have had the same problem the lights work they done work correctly and its hard to tell .Make sure they are the correct bulbs
