    my truck is 06 no 05. i was told there is no 4x4 module behind the glove box.

  • james gates Jan 19, 2013

    remove the love box and the lower shield look in to the left ,like 4-6 inches.the module should either bemounted to thedash frame the metal part of the dash, or the plenuim chamber . the chamber is the plastic part behind the dash that houses the a/c and the heater. the last shot i would try would be behind the rear interior panel about mid body . i hope this help. you can try to go to one of the techs in the shop at a ford dealer, just walk in the shop door next to the roll door tip the guy and they will give you a picture and the print out o diag for the whole system if you ask for it . then again thats what the do. i worked for ford until i had an injury at work, 20 years

SECTION 308-07A: Transfer Case - General Information 2002 F-150 Workshop Manual DESCRIPTION AND OPERATION Procedure revision date: 06/20/2001 Transfer Case - Electronic Shift on the Fly (ESOF) Operation The electronic shift on the fly (ESOF) system is an electronic shift 4x4 system that allows the operator to choose between two different 4x4 modes as well as 2-wheel drive. The operator can switch between 2WD and 4H mode at speeds up to 88 km/h (55 mph). To engage or disengage 4L range, the vehicle speed must be less than 5 km/h (3 mph), the brake pedal depressed, and the transmission must be in NEUTRAL.
The transfer case is equipped with an electromagnetic clutch which is located inside the case. This clutch is used to spin up the front driveline when shifting from 2WD to 4H mode at speed. When the control switch on the instrument panel is turned, the generic electronic module (GEM) recognizes that a shift has been requested and activates the electromagnetic clutch and the relays which power the transfer case shift motor. When the shift motor reaches the desired position, as determined by the contact plate position inputs to the GEM, power to the shift relays and motors will be removed. When the transfer case front and rear output shafts are synchronized, the spring loaded lockup collar mechanically engages the mainshaft hub to the drive sprocket. Finally, the front axle collar is engaged and the electromagnetic clutch is deactivated.
Shifts between 2WD and 4H can be made at any speed up to 88 km/h (55 mph). Listed below are the inputs and outputs needed by the GEM to execute a change between any of these modes.
Feature Inputs:
  • 4WD mode switch (various resistances; go to Table 1).
  • Contact plate position inputs A, B, C, D (grounded when closed, open circuit when open; go to Table 4).
Feature Outputs:
  • 4x4 shift motor relay outputs (go to Table 2).
  • Transfer case clutch relay (grounded when relay is activated, open circuit when relay is deactivated).
  • 4x2/4x4 vacuum solenoid (grounded when activated, open circuit when deactivated).
  • Cluster indicators (ground when activated, open circuit when deactivated).
When shifting into or out of 4L, the GEM requires that the vehicle speed be less than 5 km/h (3 mph), the brake is applied, and the transmission is in NEUTRAL.
Feature Inputs:
  • 4WD Mode Switch (various resistances; go to Table 1).
  • Contact Plate Position Inputs A, B, C, D (grounded when closed, open circuit when open; go to Table 4).
  • Output Speed Shaft (OSS) Sensor (Sinusoid Signal: 0.7V-20V, 2.2 Hz/mph).
  • Brake Input (battery voltage when brake is depressed, open circuit when not activated).
  • Transmission Range Sensor (grounded when transmission is in NEUTRAL, open circuit otherwise).
  • Start/Clutch Depressed Input (go to Table 3).
Feature Outputs:
  • 4x4 Shift Motor Relay Outputs (go to Table 2).
  • 4x2/4x4 Vacuum Solenoid (grounded when activated, open circuit when deactivated).
  • Cluster Indicators (grounded when activated, open circuit when deactivated).

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.

Truck wont start on starting fluid it is a ford f350 2001 v10


I would think that you have a spark problem. There is an Ignition Relay or ECC Relay. Your need to know certain Pin connectors to test the functions of the Crankshaft sensor and Camshaft sensors.

You may have a "check engine" light showing on the dash and it is not apparent because the dash lights have not cycled off with a no start condition. You may be able to scan the truck for a diagnosis.

While you may have fuel pressure at the test port, your injectors may not be opening. But since you used starting fluid to no avail, most likely you lack spark.

Your truck should have an ECC or Ignition Relay and perhaps an ECC diode. These parts provide power to the other components of the spark system. The secondary parts like Crankshaft sensors, the Camshaft sensors, and others use the power from these Relays.

You can satisfy yourself about fuel pressure by checking pressure at the test port, but spark seems to be your issue.

Please comment on my info.

Check fuse 28 in the fuse block under the left side of the dash. There is also a relay for the trailer park lamps in that same fuse block. The fuse and relay are the trailer parking lamps and run independantly of the vehicles parking lights. You can also try backprobing the other trailer plug (you should have one 7 pin and one 4 pin) to see if there is power at the park light pin. If there is power at the other trailer plug than the fuse and relay are bad and you may have a bad/corroded plug or bad wring to the plug that doesn't work.

Replaced starter on f350 7.3l wont crank nopower


There should be a starter relay up by the battery on the inner fender, right side of the vehicle. There is also a starter solenoid on the starter, correct? I'm going to ask if you have it in park, neutral or the clutch pushed in, if so still no crank? On the starter relay, on the fender, there are 2 large teminals and 1 small. With vehicle in park or neutral and brake set pull the small wire off and using a jumper lead put 12V to the small terminal, the engine should crank. If so now check and see if you have power to that small wire when you turn the key to start. If not it could be the neutral safety switch, clutch switch (manual trans) or the ignition switch. There is also a fusable link that comes off the starter relay that could have blown. Do you have power to the ignition, do the lights come on, on the dash, when you turn the key on? If so the fuseable link is probably OK. If it don't crank by jumping the starter relay the problem is between the relay and starter. That relay sends a signal to the starter solenoid.

Glow plugs has life span of 3-4 years.

Less if your glow plugs relay is on its way out.

Check the batteries terminal for corrosion.

Check the cable and ground connections

I have no power to my transfer case shift motor


All the relays? How about the one located behind the glove box (on many Ford 4X4's)?
Do you hear it click?

Put a test lamp on the connector, and see if it lights up on engagement of the button to engage 4X4.

Also, If you have an Autozone store nearby, you can purchase the motor, test it, and if that still doesn't work, return it, as long as it is in like new and re-sellable condition!
