Passenger Side Mirror Impact, now getting Cross-Traffic and Blind Spot System Faults

[ppmax5000]

I debated posting this in the Issues/Repairs sub-forum but thought it might be better to post here...please advise if my instincts weren't correct...

As the thread title says, my passenger side mirror got wacked which resulted in minimal actual damage to all the plastic...but the mirror plate itself was knocked loose and was hanging by various wires after the impact. I checked all the connections (a total of 3 I believe) and snapped the mirror back into place. Unfortunately I am now getting Cross-Traffic System Fault and Blind Spot System Fault each time I drive (screenshots below)

It may well be that there is some component that is broken/damaged and needs replacement. However, it appears my cameras and LED Zone Lights are functioning properly so I assume these systems would work since the camera works.

My questions are:
Are the faults I'm seeing representative of "an event" that was logged when the mirror was wacked? Can these faults be cleared using FORScan? I've got the app and a cable and would love to give it a go. Any tips/guidance would be highly appreciated
OR:
Are these faults representative of a persistent malfunction that can only be fixed by replacing/repairing something in the mirror assembly or the entire mirror assembly?

Thanks again for any info or suggestions

You can read the Diagnostic Trouble Codes (DTC) with FORScan. It will let you know if the DTC is previously set/ not present now or if it is present now. You can also clear them to see if they come back. I would Google the DTC codes it gives you first to see if others have a solution.

You do not need an extended license to read and clear DTC's. Since you said you have a cable I assume you are using the Windows version.

Inside the mirror is the blind spot indicator led. It's possible the led is non functional now thus creating the fault as it can't properly warn of blind spot traffic.

Wow, fantastic information and replies, thank you both!

@bmwhitetx
Thanks for all the details specifically the point about needing a license or not
I’ll hook up the cable this weekend.

@Heliian
Great point regarding the LED. I don’t know if I’ve seen either LED on either side light up but I actually haven’t driven on the street since the mirror wack happen yesterday evening. I’ll find out tomorrow on way tonwork
