Aftertreatment Regeneration Help Please!!!

My ATS indicator light started flashing (level 2) on my dash. I'm surprised my highway automatic regeneration hasn't started because it's been about 2K miles since the last one.


I pulled over at rest area to perform a parked regeneration, but it fails and I get an error message when it was doing the "Data Transfer" then it reads to check the Status Menu. This is what I get:


Clutch N/A
Service Brake N/A
PTO Status OK
Acc Pedal OK
Neutral OK
Vehicle Above Speed OK
Park Brake OK
System Fault CHECK
System Timeout NA
Temp lockout OK
Permanent Lockout ok
ENgine Temp OK
Exhaust Temp N/A
Vehicle Below Speed NA
Inhibit Switch OK


When I check the Engine ECU I get no errors. And no errors in the other ECUs


I'm about 200 miles from nearest city. I'm not sure if I should drive that way and take it to a shop or if this is something I can fix myself until I get home (about 700 miles away) and take to a shop there. Has anyone run into this issue? I would appreciate any help. Thanks in advance.

Shut truck off then turned it back on after about 30 minutes. Now my engine ECU has the following code:

MID 128 PPID 328 FMI 7

i was able to find online that the "Fault Condition is: After Treatment Fuel Injector stuck closed" and "Possible Cause is Shut off valve stuck closed"

I don't know if I can take out the aftertreatment injector myself (I'm guessing that's the 7th Injector) and clean it out.

 

Well was able to drive home. Cleaned out the 7th injector and that solved the problem.

*Side note*
I broke one of the two mounting bolts when removing the injector. The dealerships in my area don't sell the bolts by themselves (and they wouldn't give me the specs of the bolts), and they only sold them in a injector repair kit. Called 3 dealerships and price ranged between $75-$100 for the kit. Found the bolts at Napa for $.99 the size used was M6-60MM
