Code 154 is for missing calibration.
Code 193 is internal camera fault. Possibly due to the 087 code. (These cameras do not fail.)
Code 087 Bus signal missing. (Remove the camera cover and make sure that the camera wires are connected and not just set in place.)
Code 81f, keyless system (probably not related to the camera issue.)
The connector in the yellow circle should be your FSM.
4/80, FSM in wiring diagram. Check fuse F5 in CEM.
I do not remember if this camera/radar will auto calibrate, or you set it up in VIDA and drive until the calibrate message turns off in DIM.
If lose wire or fuse, the codes will need to be erased before calibration will take place.
VIDA description of each code.

FSM-C100154 Vision System Camera. System Programming Failures. Missing calibration

FSM-C100193 Vision System Camera. Component Failures. No operation
Diagnostic trouble code (DTC) information FSM-C100193
The Forward Sensing Module (FSM) monitors the function in the integrated forward facing camera.
The diagnostic trouble code is generated if the control module detects:
Internal fault in the forward facing camera. (My guess, wire not connected or blown F5)

FSM-U300087 Control Module. Bus Signal / Message Failures. Missing message
Diagnostic trouble code (DTC) information FSM-U300087
The control module checks communication with the image processing processor for the camera. The image processing processor is a small internal component in Forward Sensing Module (FSM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
Communication with image processing processor is interfered with or is lost.

KVM-B10C81F Interior centre antenna. General Electrical Failures. Circuit intermittent
Diagnostic trouble code (DTC) information KVM-B10C81F
The diagnostic trouble code (DTC) is stored if the control module detects that:
An electrical fault has occurred in the remote control or in the cables to the antenna.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
Engine on and vehicle speed over 19 km/h.
No keyless functionality

 

Thanks for the quick reply vg. I have checked the plug at the camera and it was tight. I will recheck to make sure no wires or post are damaged or out of place. I did check the fuse in the interior fb b #19 (collision warning system) but forgot to check #5. I'll check that tonight. If fuse is good is there any way check the canbus circuit. I'm like you I find it hard the believe the camera is bad. The funny thing is that the guys from the glass company who replaced the windshield didn't even disconnect any of the wiring from the cameras, just the rain sensor and rear view mirror.

 

I've checked #5 fuse in fuse panel B and it was good. What does it take to check canbus signals? Does VIDA have the capability to do it?

 

Here’s a fun fact about the camera in the windshield, there are 2 clips on the front and rear that secure the module to the windshield itself, BUT the Forward Sensing Module itself is two pieces held in by a ribbon cable (the lower module and the camera scanner). Those two pieces are held together with 4 clips around the module that are visible and accessible from the outside. If you release the 4 clips and pull the module down, you’re not releasing the entire module itself, you’re releasing just the bottom part and snapping the ribbon cable (it’s not very long), breaking the Forward Sensing Module itself. It’s very deceptive. There’s no screws or anything that hold the module together. I’d put money on that Module being R&I’d incorrectly.

Ask me how I know and what my car’s symptoms were when I broke it.

I’m having the exact same problem atm with my V40. I’ve bought a second hand FSM with the same part number. From what I’ve read they have to be programmed to the car right, it’s not a straight swap and recalibration ?

 

Did you replace it or repair it? If replaced, did you do it or Volvo do it? A new module is expensive (around $600.00) and would require programming for the computer (ecm) to recognize it. Then it would have to be recalibrated before all the functions would be restored. I have yet to resolve the issue with mine because I want to make sure it's not a wiring or canbus problem. The guys that replaced the windshield did not take the camera apart. I was there the whole time watching the process and the only thing that seemed out of place was that they had to cut two metal pieces at the top center of the windshield to get the windshield to release. After the windshield was removed they removed the two remaining pieces of metal when they trimed the sealant down to the desired height before reapplying the new sealant/adhesive to the windshield frame. I looked at the wiring that comes out of the headliner to all the components on the windshield and did not see any cuts or abrasions. My next attempt to figure out the problem will be to check the canbus voltages to see if the cem is sending and receiving the signals needed thus eliminating the wiring part of the equation. That would leave the camera as the only part that could be bad.
Thanks TrstnBrtt for the reply.

 

I kind of cheated with mine - I work in auto body, so the calibration wasn’t a problem. Basically I ordered a used FSM from a recycler, took it apart and transferred the camera (with the ribbon cable attached to it) to my existing FSM and installed it. The calibration went successfully. For a 2015+ the car will go into learning mode for calibration each time it is restarted- if the conditions aren’t met within half an hour it basically gives up until next time you start it.

I didn't realize you could swap out the cameras. I have a Lauch diagnostic tool that can recalibrate the FSM so I'll have to give that some thought. Even recycled they're still not cheap. I'm going to take mine apart if I determine the wiring and canbus signal are okay. At that point i guess you can't hurt it anymore than it already is. Thanks for the heads up on changing the camera only.

 

I will mention that Volvo doesn’t officially support module swaps… I’m not sure if there’s a technical reason or they would rather just make money from selling the spare parts. Either way if you are taking apart your FSM, once you pry the 4 clips off remove the camera portion from the module itself VERY slowly, peek inside and make sure that ribbon cable isn’t going to get severed. It’s quite brittle.

IF you do get one off of eBay or from a recycler make sure the part numbers are the same- there was a software change to them at some point (I think when City Safety start working at speeds to 49 KM/h from 29), as I noticed that some eBay listings were incorrectly listing the radar sensor as the camera, which is obviously not correct. You should keep us updated, I’m super invested now!

Thanks, I will be very careful when I take it apart should I need to do so.

 

I took the module apart yesterday and sure enough the wiring was completely broke in two. Looked like someone cut it with scissors. Now to get another one on order and swap out the camera. Why are these flat cables so susceptible to breaking. I plan on a little reinforcement during reassembly. Hopefully that might stop this from happening again.
TrstnBrtt, thanks again for the heads up on the camera replacement.

 

Glad it was an easy solve - good luck with it. You’ll still need to do the calibration on the car. If you’ve got a scan pad go into the FSM Module and there should be an obvious button for calibration. It’ll give you the road requirements to complete it. It’s a frustrating process, so there’s that hurdle lol

I do have a scan tool that will do the recalibration so if all goes well I should have everthing back to normal soon. I post the results when I get finished. I did have to improvise on the Torx/Allen bit to get the four screws out of the board to get the other piece of ribbon out. Other than that no problem. Wish there was a good auto recycler around I could get the module from.

 

What city/country are you in?

Tennessee USA, just a few miles south of you or kilometers. Of coarse that depends on what part of Canada you live in if your flag is an indicator of where you live.

 

I’m in Vancouver. I was going to suggest car-part.com but then you run the risk of the recycler removing it wrong too.

Wow, we're not to far apart, only about two thousand seven hundred miles. We'll I ordered a part from a recycler yesterday so in a few days I will know if they broke it or not. The guy I was talking to on the phone sent me a picture and it looked like they hadn't taken apart. If these things are so sensitive how do they survive on northern roads full of pot holes?

 

Well, I finally have good news. I received the used module yesterday and swapped the camera out but I also swapped out the top electronics board by accident. Needless to say it still showed an unmatched or not reserialized (whatever it's called, brain freeze).
I took the module back and swapped the top boards and put it back in. All I could do was to clear the codes and recheck if the module was communicating with the CEM. It did and today when my wife got home with the car I ran the camera/radar calibration procedure and in about 8mi. it worked. The "calibration not complete" message disappeared and all the functions I was missing returned.
Again I would like to thank you for your suggestion to check the camera and replacing just that.
You may or may not agree but you were a God send.

Clearly the glass company took little care when they replaced it and damaged the cable. They should have paid for it.

 

Well if I could have proved that they did it then I would have made them pay for it. If I had had Volvo order and replace the module as well as calibrate it, it would have cost the insurance company around $1300. Instead it will cost them $123 and I will have learned how to fix this system and always watch more closely when someone is working on my car.

Have you taken the old one apart to see if the ribbon is broken in to? If the ribbon is bad just change out the camera and ribbon and you should be good to go. It still might have to be recalibrated but that is better than having Volvo replace the whole assembly and recalibrate it. If the ribbon is good then you may have to replace the whole assembly and have it matched up vin wise. Last thing, are you sure your FSM is your problem?

 

Yeah I’m sure it’s my FSM that is the problem. It’s creates 2 DTCs intermittently, the failed calibration one and the image processing one. Sometimes it doesn’t read the signs properly and then sometimes it works perfectly fine. I’ve had issue with it from day one owning the car as it doesn’t clip onto my windscreen properly(I believe it’s been changed and it’s not an original Volvo windscreen).

 

Could the non original windshield be the problem? The fact that it does work sporadically sounds like something could be loose/not mounted securely. Hope you figure out what's going on and get it fixed quickly. I know how frustrating it can be to have a problem that is hard get solved.

 

To be fair I think it is causing the problem as it’s come loose before, and when I clipped it back it worked again. I’ve bought a second hand one from a breaker car so if it does kick the bucket I’ll replace it. Unfortunately most windscreen companies through insurance don’t replace with original Volvo windscreens.

 

My wife's 2015 S60 T6 R-Design had to have the windshield replaced due to a rock that cracked it bad enough to warrant it being replaced. I guess it could have been due to the defrost wires in the windshield but they had to use a factory replacement. The funny thing was that before the replacement everything worked perfectly. After it was replaced the camera did not work and they couldn't recalibrate it. After the third try including a Volvo dealership, which said I needed to replace the camera assembly and would have cost the insurance company about $1100, I just decided to do it myself. The guys that replaced the windshield probably were the cause of the issue. I didn't have any real proof so I just told the insurance company to reimburse me for the camera module witch I got for $120. Once I got everything swapped out I was able to recalibrate it and be done with the issue. You might have to get a factory windshield to permanently solve your problem. Even one from an auto recycler would probably be better than what you have now.

 

Yeah that’s true. I’m certain the windshield isn’t a Volvo one as there’s no Volvo logo on it anywhere. I didn’t own the car at the time when it was supposedly replaced so who knows what botched job they’ve done. I really hope it doesn’t resort to needing a new windscreen. Second hand unit is arriving today so might have a play about with it. Also need to find someone that could program it to my car, I’m not sure if they are linked or not VIN numbers. VIDA states just gotta do a FSM reload but that might only apply to a brand new unit.

 

When you take the original unit out very carefully disassemble it to check the flat wiring cable to see if it is broken or cut anywhere. If it is then just replacing it with a good camera and cable is all you need, no reload necessary. If there is no evidence that the cable is the problem and you have to replace the FSM then yes it will have to be reconfigured to your car to communicate with the other modules. Hope you find someone in your area to help you out.
