4x4 low light on car will not move


The electronic module (located behind the glove compartment) controls the operation of the transfer case in response to inputs from the electric shift motor, 4x4 mode switch, CPP switch, BPP switch, DTR sensor, throttle position output from the PCM, front and rear OSS sensors, and the VSS. Do you know what DTC'S Are ? Diagnostic trouble codes !

I'm assuming you have Transfer Case -Automatic Four Wheel Drive (A4WD) An not Transfer Case -All-Wheel Drive (AWD) Two different system's . The automatic system is electroniclly controlled . When it has electrical problems it set DTC'S - diagnostic trouble code's in the 4X4 control module . Before replacing part's or trying this an trying that , having the vehicle checked for DTC'S is always the first step in any diagnostic's with these vehicles . Then if not familiar with this system read factroy service repair information . Trying to fix not knowing what your doing never works .
System Function
Hall effect sensor monitors input and output shaft speed.
In the A4WD (C-Trac) system, the GEM varies the torque sent to the front driveline by controlling the transfer case clutch. At rest and under cruising conditions, the GEM activates the transfer case clutch a minimum duty cycle (percentage of time the clutch is turned on), which allows for the slight difference between the front and rear driveshafts which normally occurs when negotiating a corner on dry pavement. Under any of the following conditions, the GEM will increase the duty cycle in order to prevent or control slip:
  • Slip is detected (by using the Hall Effect Sensors)
  • Heavy acceleration (throttle position).
Feature inputs:
  • Brake ON/OFF switch.
  • 4WD mode switch.
  • Digital transmission range sensor.
  • Clutch switch (manual transmission vehicles only).
  • Vehicle speed signal (transmitted from the ABS module).
  • Front/rear driveshaft speed sensors.
  • Throttle position information from the PCM.
  • Contact plate position inputs A, B, C, D.
Feature outputs:
  • Solid state clutch relay (pulse width modulated signal: grounded when relay is on, battery potential when relay is off).
  • A4WD indicator (ground when activated, open circuit when deactivated).
  • 4x4 shift motor relay outputs.
Shifts between A4WD and 4x4 HIGH can be made at any speed. Listed below are the inputs and outputs needed by the GEM to execute a change between any of these modes.
Feature inputs:
  • Front/rear driveshaft speed sensor.
  • Vehicle speed signal.
  • Throttle position information.
  • 4WD mode switch.
Feature outputs:
  • Solid state clutch relay (pulse width modulated signal; grounded when relay is on, battery potential when relay is off).
  • 4x4 HIGH cluster indicator (ground when activated, open circuit when deactivated).
When shifting into or out of LOW range, the GEM requires that the vehicle speed is less than 5 km/h (3 mph), the brake is applied, and the transmission is in NEUTRAL.
Feature inputs:
  • Throttle position information.
  • 4WD mode switch.
  • Contact plate position inputs A, B, C, D.
  • Vehicle speed signal (transmitted from ABS module).
  • Brake ON/OFF switch input (battery voltage when brake is depressed, open circuit when not activated).
  • Digital transmission range sensor (ground when transmission is in NEUTRAL, open circuit otherwise).
  • Start/clutch depressed input (manual transmission only).
Feature outputs:
  • 4x4 shift motor relay outputs.
  • 4LOW cluster indicators (ground when activated, open circuit when deactivated).
  • Solid state clutch relay (pulse width modulated signal; grounded when relay is on, battery potential when relay is off).
  • The GEM they talk about is a generic electronic control module .

The 4X4 system on your vehicle is computer controlled , GEM module . generic electronic module . The four wheel drive mode switch is a low voltage input to the GEM module . The GEM energizes relay's to control the mode as depicted by input from the mode switch an torque on demand relay an someother inputs . Probably has DTC - diagnostic trouble codes stored in the GEM module .
Transfer Case -Automatic Four-Wheel Drive (A4WD) The automatic 4-wheel drive transfer case system consists of the following:
  • automatic 4WD indicator light
  • brake pedal position (BPP) switch
  • torque on demand (TOD) relay
  • front output shaft speed sensor
  • generic electronic module (GEM)
  • 4WD high indicator light
  • 4WD low indicator light

Could you tell me some of the things that may set off the following codes P0742, P1573, P1811


P0742 - Torque converter clutch solenoid circuit stuck on
P1573 - Connection lost between ABS Module and PCM
P1811 - code P1811 will set if a shift into any gear other than reverse and forward engagements takes longer than 0.65 seconds to complete

The 11 codes supposedly fixed during the first trip to the dealership: P1781, P1851, P1860, P1866, P1868, P1870, P1873, P1878, P1880, P1874, C1522 Again here is the last information and the suggested...


I'am guessing it is a manual trans with internal damage. Yes,if so,it will have to come out and be disassembled to find cause. With clutch work,your looking at around $3000.00.

Rebuild Trans
Maybe a couple new sensors
Machine Flywheel
New clutch
New clutch slave

ECU-should be okey

You will need the code to get it working. You may need Audi for this. Never disconnect the battery, or the alarm with trip on. Since it is frozen, I would try and remove the fuse, and reinstall it to reset the stereo. Then try the code.
I got lucky in my 2001 VW passat, when the stereo code was needed, but then the next day it started working by itself.
