The body control system consists of the following 2 modules:
• The Dash Integration Module (DIM)
• The Rear Integration Module (RIM)
Each of the 2 body control modules integrate a number of functional systems. Each module is connected to the class 2 serial data circuit, many of the control signals are implemented by class 2 messages.
Dash Integration Module (DIM)
The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
The DIM functions include the following:
• cigar lighter relay control
• class 2 communication requiring DIM interaction
• exterior lighting control
• headlamp washer control
• hood ajar switch input w/export
• horn relay control
• interior lighting control
• load management
• low side temperature for HVAC compressor
• park key lock output
• power moding control over Class 2 serial data circuit
• reverse lockout solenoid control
• steering wheel controls input
• storage of the clock settings and, sending a message out on the class 2 serial data circuit in response to requests from other modules
• storage of vehicle options and configuration
Serial Data Power Mode
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle the PMM is the DIM. The PMM receives 2 signals from the ignition switch.
To determine the correct power mode the PMM uses the following circuits:

Fail-safe Operation
Since the operation of the vehicle systems depends on the power mode, there is a fail-safe plan in place should the PMM fail to send a power mode message. The fail-safe plan covers those modules using exclusively serial data control of power mode as well as those modules with discrete ignition signal inputs.
Serial Data Messages
The modules that depend exclusively on serial data messages for power modes stay in the state dictated by the last valid PMM message until they can check for the engine run flag status on the serial data circuits. If the PMM fails, the modules monitor the serial data circuit for the engine run flag serial data. If the engine run flag serial data is True, indicating that the engine is running, the modules fail-safe to RUN. In this state the modules and their subsystems can support all operator requirements. If the engine run flag serial data is False, indicating that the engine is not running, the modules fail-safe to OFF-AWAKE. In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.
Discrete Ignition Signals
Those modules that have discrete ignition signal inputs also remain in the state dictated by the last valid PMM message received on the serial data circuits. They then check the state of their discrete ignition input to determine the current valid state. If the discrete ignition input is active, battery positive voltage, the modules will fail-safe to the RUN power mode. If the discrete ignition input is not active, open or 0 voltage, the modules will fail-safe to OFF-AWAKE. In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.
Replacing either one of these module requires programming .
Program the module. Refer to Body Control Module (BCM) Programming/RPO Configuration
Are you sure you want to mess with these .

Your best bet would be to take your vehicle to the dealer ! You have no idea of the complexity involved in the starting of this vehicle ! The computer contols and serial data network etc....

Honestly ,there is nothing you can do ! The dealer has the factory scan tool an service info. to diagnose this quickly . The only thing you would be able to do is guess as to what the problem is ,and it would be wrong .

What do you mean no sound when turning key ? Does the car start an run ? Or the car doesn't crank ? Ignition switch's do not work the same way they did in the old days , especially on GM vehicles . The ignition switch is an input to the BCM - body control module , the BCM processes these inputs an then energizes relays to turn things on . Also sends messages to other modules for them to turn on or energize relays .
The power mode signal may be as simple as a B+ input wired to a particular ignition switch contact. If this is also the B+ supply to the module/device, the module/device will only operate with the ignition contact closed to B+. An example of this is the starter relay when it is wired directly to the CRANK/START contact of the ignition switch. When the CRANK/START contacts are closed, the starter relay is energized and provides a current source to the starter and starter solenoid. When the ignition switch leaves the CRANK/START position, the switch contacts open and the starter relay is de-energized. This removes the current source from the starter and solenoid and the starter operation stops.
Serial Data Power Mode
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle the PMM is the Body Control Module (BCM). The BCM receives 4 signals/circuits from the ignition switch. These are the Ignition 0, Ignition 1, Crank and Accessory 1 ignition switch signals/circuits.
To determine the correct power mode the BCM uses:
?€¢
The state of these signals/circuits, either switch closed (B+ = 1) or switch open (open = 0)

?€¢
The sequence of switch closures received by the BCM

?€¢
The status of the engine run flag.

Important: Any ignition switch states not covered in this table indicates a DTC setting situation.

You probably won't understand any of this info. your best but would be to take it to a qualified repair shop that has proper diagnostic test equipment !

First off you need to know the level of complexity of your vehicle before you can understand the how an why's . Your vehicle is electronically controlled by Modules , BCM , PCM , Instrument cluster , ABS , Air bags , the doors even have modules inside an I'm sure there are a few more . These modules all talk to ,share information on serial data communication networks GMLAN , Class 2 data bus etc... http://www.aa1car.com/library/can_systems.htm. When you turn the key the electric part of the ignition switch sends Discrete Ignition Signals to the BCM . The BCM then energizes different relays supplying power to different systems on the vehicle. If there is no problem with the anti-theft system the BCM sends a message to the PCM that a engine crank has been requested , then the PCM energizes the crank relay permitting the engine to crank an run . So to say this could be this or that problem would be unprofessional on any Technicians part . The first thing would be to hook up a factory scan tool or a professional grade one an check for DTC'S - diagnostic trouble codes .
Serial Data Messages The modules that depend exclusively on serial data messages for power modes stay in the state dictated by the last valid PMM message until they can check for the engine run flag status on the serial data circuits. If the PMM fails, the modules monitor the serial data circuit for the engine run flag serial data.

In this state the modules and their subsystems can support all operator requirements. If the engine run flag serial data is False, indicating that the engine is not running, the modules fail-safe to "OFF-AWAKE". In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.

So , if your not familiar with these thing's the best thing would be to take it to a ASE certified repair facility .

why not stated the symptoms.
cranks ok, or not. Dead starter?
wont start at all
or starts for 2 seconds but stalls, or ???????

IS this a STOCK security? system?
if your car has security engine cut out, that needs to be fixed
or in rare cases (bypass/modified/hacked)
on most cars only early systems are hackable. (ask why,)

there are many causes. but #1 is , does it crank ok.?
there are many ways for the security systems to fail (and friends)
the shifter PRNDL switch loves to fail. killing cranking, try cranking in neutral, bingo?
then there is the security system. and the funky keys they use.
if real serious, DIY, get the FSM , and see all the tests there for the
sec. modules.
or alldata.com

many old cars 92 the online documents are bad. poor
the FSM is not poor its dead accurte,
buyone, on ebay used, or near nothing.
on old cars, this IS THE BEST advice.....

Try closing your doors, then using the key (not the auto lock fob) lock the doors then using the key again, unlock the door. Try starting the car again, it should work. If not, have it towed to a dealership, they can fix the issue

sounds like your cars computer is having issues running the engine at normal settings.

You should get the computer codes read to see if there is a failing sensor or other component.

Low fuel pressure could also be an issue if the sensors are all in spec. That test is something a mechanic with a pressure tester can check out.

Good luck and be careful.

There is a sensor on the back side of the tumblers in your ignition switch. This is the pass key sensor. Its bad. Have your switch replaced. Don't let anyone try to trouble shoot this. I have had to replace about 125 of these and they always crank and run afterward. Hope this helps. Good luck.
