You'll need a new ABS module. Also need a new IMPA camera/module.
The parts you need should match the list I provided since @NMMI82 and I both have 502a with factory LKA.

If you have a non 502a Lariat I think you should verify the correct wires are present at the bumper for the CCM (radar module) harness. It's been a while, I don't recall if that is XLT to Lariat or within Lariat trims.

I have LED's so I'm assuming the wiring harness would need to be changed to have the CCM module connector. My camera is JL3T-19H406-AG. No idea about the ABS module.

So far, I still think my instructions / parts list are what you need.

Thank You,

first off just wanted to thank everyone for their contributions. I have been trying to add ACC to my 2018 Lariat 502A with Tech Pkg. I have all the hardware installed and an running into an issue with IPMA calibration.

In FORScan, I have the following two DTCs. No matter what I do I cannot clear them:
IPMA: C1001 - Missing Calibration
IPMA: U2100 - Initial Configuration Not Complete

I just thought they would go away once I did the IPMA calibration but that leads me to the next problem. I select IPMA Lane Departure Camera Calibration in ForSCAN and it asks me to verify my wheel arch length (990mm) and I click okay. It then says to wait 60 seconds (after starting the truck) and every single time it errors out at 60% and says "Service procedure has been interrupted." It doesn't even get to the calibration part.

Anyone have any ideas? I have triple checked all the values that I entered in the IPMA, IPC, SCCM, BCM and CCM. Also took out the IPMA and verified cable connection. I haven't done the ABS one as that was gonna be last.

Thanks for any guidance or help.
