Here's a starting point in identifying trouble codes. https://blazerforum.com/forum/diagno...codes-dtcs-49/

When a DTC, (Diagnostic Trouble Code) sets in memory, additional DTC's may be set after it, and they may or may not actually be a problem. When troubleshooting DTC's, the first one set must be diagnosed, repaired, and a General Motors Driving Cycle must be performed to confirm the repair.
When multiple DTC's are set, write them down in the order they are retrieved. Then clear all of the memories: pending, current and history. Entry level scan tools, (those less than ~$1500) will not access the history files. After memories are cleared, perform the General Motors Driving Cycle and retrieve the DTC's. Then diagnose and repair the first one retrieved, and repeat the drive cycle to confirm the repair. Repeat the process until no DTC's are present after the drive cycle is performed.
Keep in mind that disconnecting the battery does NOT clear DTC's in the history file. It will turn the check engine light off, unless there is a hard fault present, in which case, it will come right back on.
The drive cycle instructions for each step must be followed exactly as written. Each step must be performed, but the steps do not need to be performed in order.

The first 4 codes for the chassis is for the front abs signals missing and the last one is the transfer case failed to shift. Failing to shift could be caused by several things.

Did you see post #4? DTC's never tell you that parts are bad. They tell you what circuit is/was out of range.

They are in the exhaust before the cat converter. I'd check for a blown o2 sensor heater circuit fuse too.
