See below. Note: I do not have trailer tow, autopark, or a tow trailer brake module.

Comparing your SODL/SODR as-built files to the ones in tmcolger's how to, you have many discrepencies. That might be your problem.

Senator

FORScan wouldn't even write the values on the how-to. I used Livinitup's values from a PM, and those at least allow me to write to the module.I think his values are for pre-18 modules when you look at his own side by side comparison.

From FORScan sheet:
7C4/7C6-01-01 **xx xxxx
9B=with trailer tow, Auto Trans, LH Drive, RPA:yes, BTT:yes
1B=less trailer tow, Auto Trans, LH Drive, RPA:yes, BTT: yes

From Instructions:
SODL (Side Object Detection Left):
o 7C4-01-01 9800 0065

Interesting, are you using 2018 BLIS modules?

Senator

Update: I don't think it's my wiring that I ran from C405 to C327.
I moved the 4 terminals in C405 that I ran (to a mirror image - wrong places).
Now I get DTC for IPC : U0232 & U0233- Lost Communication with SOD module right (left), and the invalid data DTC.
I wired them back according to the diagram, and only get the invalid data DTC.

Senator

Yes 2018 tails with the 2018 modules. Checked the part number yesterday when I had them out.
The only things I can think of left:
1. Bad SODR/L modules?
2. Short to voltage somewhere in my doors for the BLIS LED circuit?
3. Not sure what year Lariat cluster I have (got it from Livinitup) - IPC/SODLR/DDM&PPM aren't playing nice, since they are prob different years?
4. Need different SODL/R programming? Maybe from 2018 XLT 302a with BLIS?

Has anyone succesfully used 2018 modules on a 2015-2016 truck? I thought the firmware was different and they weren't compatable?

Livnitup

Looking at it now....

Senator

Livinitup's truck is a 2016 with 2018 modules, BUT he has a 2018 IPC I believe. I'm wondering if that's a potential issue since I can't get the IPC to show the BLIS/CTA check boxes until I remove a connector in the BLIS system.

Livnitup

I don't see anything wrong in the programming that stands out in SODL/SODR and I double-checked your VIN coding. You've got BLIS configured in DDM/PDM 740/41-04-01 x*xx xx too right? I don't think the fact that I have an '18 cluster in my '16 would matter with the BLIS/CTA working but I can double-check that next week when I get some 2016 8" clusters in stock if you haven't narrowed it down by then. I can still conceivably see that a wiring issue may force that BLIS LED on which in turn could grey-out the BLIS/CTA checkboxes on the cluster.

It might be worth a try using 7C4/7C6-01-01 9B01 xxxx xxxx just to see if that has any impact but I doubt it will.
