Service 4WD System error

So a couple weeks ago I start up and get the error.

I have an 08 CRD WK Limited

Have tried pulling fuse 33 > Did not work

The other day it stopped showing up. Still unable to shift into 4Lo.

Here are the codes.
C2109 - Chassis

C1458 - Chassis

P0700 Power Train
Transmission Control System (MIL Request)

U0114 - Network

Any thoughts and suggestions would be most helpful

Re: Service 4WD System error

The first time this happened to me years ago, the Jeep dealer replaced the final drive control module itself. The issue was resolved and was back when the Jeep was under extended warranty. A few years later there was a recall for a final drive control module reprogramming. Dealer reprogrammed it and i started to get the service 4wd system message off and on a few months later. Just the other day i took the Jeep in for another recall to re-reprogram the final drive control module and get the ignition switch replaced and i have not had the service 4wd system error message since the latest reprogram. Hope this helps.

The service 4 wd light came on and the vehicle went into 4 lo. Able to get out of 4 low with difficulty. Just had ignition recall completed before Christmas.
Any suggestions.

Did you have the 4wheel drive system recall done?

Which recall? Had the N23 done.
Also, found tsb which refers to this problem.
