SOURCE: Electronic Control Module Installation 1994 G20 Chevy Van

I just had the same problem. If it is a regular van try under the driver seat in a plastic box. If it is a conversion van try in a pannel just behind driver seat on side of van wall behind a pannel that looks like a vent.

The control module ID number list below provides a method for determining which module is not communicating. A module with a class 2 serial data circuit malfunction or which loses power during the current ignition cycle will have a Loss of Communication DTC set by other modules that depend on information from that failed module. The modules that can communicate will set a DTC indicating the module that cannot communicate. When no message is detected from a learned identification number for 5 seconds, a DTC U1??? where ??? is equal to the 3-digit identification number is set.

    OPERATION

    When the term Electronic Control Module (ECM) is used in this guide it will refer to the engine control computer regardless that it may be a Vehicle Control Module (VCM), Powertrain Control Module (PCM) or Engine Control Module (ECM).
    The Electronic Control Module (ECM) is required to maintain the exhaust emissions at acceptable levels. The module is a small, solid state computer which receives signals from many sources and sensors; it uses these data to make judgments about operating conditions and then control output signals to the fuel and emission systems to match the current requirements.
    Engines coupled to electronically controlled transmissions employ a Powertrain Control Module (PCM) or Vehicle Control Module (VCM) to oversee both engine and transmission operation. The integrated functions of engine and transmission control allow accurate gear selection and improved fuel economy.
    In the event of an ECM failure, the system will default to a pre-programmed set of values. These are compromise values which allow the engine to operate, although at a reduced efficiency. This is variously known as the default, limp-in or back-up mode. Driveability is almost always affected when the ECM enters this mode.


    REMOVAL & INSTALLATION

    See Figures 1 and 2


    0900c152800a7f96.jpg enlarge_icon.gifenlarge_tooltip.gif

    Fig. Fig. 1: ECM mounting scheme-except 1996 models


    0900c152800a7f97.jpg enlarge_icon.gifenlarge_tooltip.gif

    Fig. Fig. 2: ECM mounting scheme-1996 models
    The ECM is located in the passenger side footwell in the kick panel up to 1996. In 1996, the ECM is located in the engine compartment next to the battery.

    1. Disconnect the negative battery cable.
    2. Disengage the connectors from the ECM.
    3. Remove the spring retainer off and over the rail of the ECM on vehicles except 1996.
    4. Slide the ECM out of the bracket at an angle.
    5. Remove the ECM.

    To install:
    1. Install the ECM into the bracket.
    2. Install the spring retainer (except 1996) and plug in the electrical connectors.
    3. Connect the negative battery cable.

    Where is my abs/tcs module on my 05 devile


    {: ) The ABS/TCS module (or the Electronic Brake Control Module- EBCM ) is located at the front left lower corner of the engine compartment, under the air cleaner housing. The EBCM is attached to the brake pressure modulator valve. See sample diagram:

    Where is the transmission control module located?


    The TCM is part of the ECM (electronic control module) and is not a separate module. The ECM is located behind and to the right of the glove box, you will need to remove the glove box liner to gain access to it. It has a large 60 wire connector going to it.

    Transfer case grinds truck only runs in 4wheel low nothing in 4wheel high or 2wheel drive


    Manual or electronic t case?

    Section 07-07: Transfer Case, 4x4 System, Service 1994 Bronco/Econoline/F-Series Workshop Manual
    DESCRIPTION AND OPERATION Electronic Shift Operation The transfer case is equipped with a magnetic clutch, similar to an air conditioning compressor clutch, which is located inside the transfer case adjacent to the lockup collar. The clutch is used to spin up the front drive system from zero to vehicle speed in milliseconds. This spin-up allows the shift between 2-high and 4-high to be made at vehicle speeds listed in the vehicle owner's guide. The spin up engages the front lock hubs. When the transfer case rear and front output shafts reach synchronous speed, the spring-loaded lockup collar mechanically engages the mainshaft hub to the chain drive sprocket and the magnetic clutch is then deactivated. Shifts between 4-high and 4-low can only occur with the transmission safety switches closed. The vehicle's speed must also be within specified limits as determined by the transfer case speed sensor (3 mph or under). Electronic Shift Control System
    This system consists of a two-switch control system, an electronic control module, an electric shift motor (7G360) with an integral shift position sensor, and a speed sensor. Switch Control System
    There are two control switches located on the upper right corner of the instrument panel for fingertip shift control. The two switches are mounted horizontally and are identified as "4x4" and "LOW RANGE". Two indicator bar lamps are located in the instrument cluster.

    c11148a.gif

    When either of the two switches on the instrument panel control are depressed, the first thing that happens is that the electronic control module receives input from the transfer case shift position sensor to verify what position the transfer case is in (2H, 4H or 4L). Next, the electronic control module looks at the speed sensor and the park/neutral position switch or clutch pedal position switch (depending on transmission type). If all conditions are correct to allow the desired shift, the electronic control module will tell the electric shift motor to execute the shift. After the shift has been made and the electric shift motor is off, the control module again looks at the shift position sensor to make sure the proper shift has been accomplished. Finally, the dash indicator light and the pushbutton light on the control panel will be illuminated by a signal from the electronic control module indicating the desired function has been completed.
    Electronic Control Module
    The electronic control module, located on the passenger side, controls the operation of the transfer case in response to inputs to the pushbutton control by the vehicle operator, the speed sensor, shift position sensor and the park/neutral position switch. Speed Sensor
    The speed sensor, mounted on the rear of the transfer case , tells the electronic control module the speed of the vehicle to allow range shifts (in or out of 4L) to occur. Shift Position Sensor
    The shift position sensor, an integral part of the electric shift motor , tells the electronic control module the shift position of the transfer case . Electric Shift Motor
    The electric shift motor , mounted externally at the rear of the transfer case , drives a rotary helical cam which moves the 2W-4W shift fork and 4H-4L reduction shift fork to the selected vehicle drive position.
