My 2005 Chevrolet avalanche 2500 8.1 vortec..cranks over but doesn't start.i put my scanner and I got loss of communication with powertrain module..

Fuse box diagram (location and assignment of electrical fuses) for Dodge Ram / Ram Pickup 1500/2500 (2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009).

Not good fuses to blow. you need to find out why?

Here are your dash warning lights. The lightning bolt is Electronic Throttle Control, and you can't drive without that. Not sure that your sail and sun is unless it is the Cold Ambient Derate Mode Indicator
You need a local auto electrician. you can't guess stuff like this, it needs a pro grade scan tool computer.

2 wheel drive , 4X4 ? Which transmission
Automatic Transmission - 4L60-E/4L65-E
Automatic Transmission - 4L80-E/4L85-E

Your vehicle has a PCM - powertrain control module . Both engine an transmission electronic's are in one module .

Powertrain Control Module (PCM)
At the left front side of the engine compartment

Do you even know what DTC U0107 involves ?
DTC U0107
Lost Communications With Throttle Actuator Control (TAC) Module

The throttle actuator control (TAC) module and the powertrain control module (PCM) communicate via a dedicated serial data circuit. This serial data circuit is separate from any other serial data circuit on the vehicle. Accurate transmitting and receiving of serial data requires not only good circuit integrity, but also adequate system voltage. This diagnostic test monitors the accuracy of the serial data transmitted between the TAC module and the PCM. If the PCM detects a loss of data or invalid data, this DTC sets.

Diagnostic Aids
Important: Reprogramming the PCM may cause a communication error between the PCM and the TAC. If the PCM detects a communication error, DTC U0107 sets. Clear any DTCs from the memory that may have been set by Reprogramming.
• DTC U0107 sets if the battery voltage is low. If the customer's concern is slow cranking or no crank because battery voltage is low, ignore DTC U0107. Clear any DTCs from memory that may have set from the low battery voltage condition.
• DTC U0107 sets when there is a short to B+ on the TAC module ground circuit. Inspect the fuses for the circuits that are in the TAC module harness--i.e. cruise, brake. An inspection of the fuses may lead you to the circuit that is shorted to the TAC module ground circuit.
Replace the TAC module. Refer to Electronic Throttle Actuator Control Module Replacement .
Did you complete the replacement?

CO 298 POWER CONTROL MODULE MALFUNCTION..
An ABS code--loss of communication with pcm/vcm.
This needs to be diagnosed by a shop.

You have an inline six engine and it is equipped with engine-mounted electronic Powertrain Control Module that records hundreds of measurements per second and makes immediate adjustments of air, fuel, spark control, and valve timing to provide optimal engine operation. Your Vortec 4200 uses an electronic throttle control (ETC). The ETC sends a series of signals from an accelerator-pedal module using a sensor that relays acceleration-intent data to the powertrain control module (PCM).
To increase idle you will have to reprogram the PCM using an OBD 2 software. Have it service at your dealer.

PRNDL Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL display blanks if:
• The PCM detects a malfunction in the transmission range switch circuit.
• The IPC receives a class 2 message indicating the park position and the column park switch indicates a position other than park, open input.
• The IPC detects a loss of class 2 communications with the PCM.

Could be the transmission range sensor . Testing would need to be done , hooking up a scan tool ! Doing electrical testing etc...

Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

On an 03 Sil SS C0298 "Powertrain Control Malfunction" H "Electronic Brake Control Module (EBCM)"
Believe this code to be same for your truck too. hope this helps

Pull your ignition module and take it to advance auto parts or autozone to have it tested.

DISCONNECT THE ECU FUSE FROM YOUR FUSE BOX. WAIT 15 SECS AND THEN RECONNECT AND START YOUR VEHICLE.
