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.

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

Probably a Bent axel I had had same problem

replace locking hubs

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

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.

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.

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

P0352 Ignition Coil 2 Primary Secondary Circuit Malfunction Wiring problem or the transistor inside the computer. Ford Ignition Coil Primary Codes P0351 P0360 Diagnostic Walkthrough

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

check the fuses

from experience just replace the plug and coil,if been along time since a plug change do all the plugs to be safe.when these motors get spark plugs that are weak it will take out the coils,if you are questioning an injector just start vehicle and listen with a stethoscope to each injector you can hear a difference from the weak one.youy can try whats called a motor vac and this at times will get clogged injectors to come back

look over by the battery. There is a plastic cover mounted to the firewall. Remove that cover and you will find the 2 main fuses. I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

My guess is, and it is only a guess, like with any computer the more things it has to remember during boot-up, the longer it will take. Cars have not been cars for some time and should be thought of as mobile computers. This is most true of models using a CAN-bus system where some functions have a high priority and some functions will not be available until the network ceases to be busy. There is probably a cure but I am a complete dinosaur.

gud luck--just buy a haynes manual at at autozone

The powerdistribution center is in a black box under the hood on the driver's side near the windshield. Hope this helps.

well this could be as simple as ford from the factory used bad wires or the modual under the coil packs could be bad and not providing power to the coil when needed also check crank and cam sensors for and junk stuck to magnets on the tips of them.

Hi Philip: Sounds like you may have a battery problem. Make sure it's fully charged and that all terminal connections are clean and not corroded. The next step would be to check the solenoid. Is it clicking? Will the motor turn over if you jump the solenoid?
