Truck lock down as no start or crank and airbags stays on codes B1019-3A as sensing and diagnostic module (SDM) system configuration ERROR INCORRECT COMPONENT and B1370-06

As no start or crank and airbags stays on codes B1019-3A as sensing and diagnostic module (SDM) system configuration ERROR INCORRECT COMPONENT and B1370-06 as device ignition 1 circuit short to ground or open -

I need a 2007 chevrolet silverado 2nd generation GM service -repair manual on this as other non-GM manual don't have the quality guide line - any luck out there.  Thanks cowboyisdeaf

I'd start at the underhood fuse block, then the SDM.  If you live anywhere corrosion occurs, the 07-13 generation trucks are known to have internal shorts from corrosion of the fuse block that cause all sorts of issues.  Check all your ignition circuit fuses.  If everything is happy, head to the SDM.

 

What module set the B1370, the BCM or the SDM?  

 

B1019 3A

• The vehicle was configured for PPS but the SDM does not detect that the PPS indicator is present due to loss of power at indicator.
• The vehicle is not configured for PPS and the SDM detects that the PPS indicator is present.

 

B1370 06

The SDM detects a short to ground or an open in the ignition 1 voltage circuit when the ignition switch is in RUN or CRANK.

-Ignition OFF, remove the Air Bag fuse from the underhood fuse center. Ignition ON, engine OFF test the voltage from the supply voltage side of the AIR BAG fuse to a ground with a DMM. The voltage should read 9–16 volts.

-If the voltage is less than 9–16 volts, refer to DTC B1370.

-Remove the SDM connector.

-With the Air Bag fuse removed, test the ignition 1 voltage circuit between the underhood fuse center and the SDM for a short to voltage or an open. Verify that a short to voltage or an open does not exist.

-If any of the above conditions are found, make the appropriate repair.

-If all circuits test normal, replace the SDM.
