Lane departure warning
So this vehicle was in hit on the drivers from wheel area. From what I am being told the bumper was not damaged at all. A used electronic power steering rack was installed and I reprogrammed with FJDS. I performed all the relearns as instructed by the service information. Their are no codes in any of the systems. The vehicle runs and drives just fine, other than the lane departure waring message light on. Has anyone ever seen this problem? Could the used rack be causing an issue? I was going to do the ADAS recalibration next for the front imaging processing module A, but I figured I would get some thoughts before I start messing with that.
Did you perform SAS relearn, yaw, etc? If not, this should be performed. Also possible the radar/bracket was damaged or fell out during the collision…. or may just need to be driven. Any fault codes?
No fault codes. I performed SAS yes. Vehicle was driven 5 miles .
I did have this issue on a F150 once with a used rack. IDS would not properly configure AsBuilt even though the process would succeed. I was able to get it to code properly with Forscan. It might have to do with the vehicle that the rack came from did not have an IPMA module.
That is a real major concern of mine also. I will give forscan a try I been wanting to get it and give it a shot but I hadn't had a use case yet.
Yes, the used rack will cause the problem with ADAS, I have had this happened before where the shop replaced the rack with a used unit, and it was causing ADAS malfunction. Replaced rack with a new unit, and all works just fine.
I'm going to give forscan a shot if its still a no go I'm going to tell them to put a new rack in. which they are prepared to do.
