First off I would like to thank you for this video I just did a 2013 Freightliner yesterday and this was the exact problem burning smell in the cab lights are flashing four ways didn't want to work turn signals didn't want to work

[@oaguilar6459]

I'm glad you fix the problem This is the reason why I make videos

[@cedthetruth1311]

@@oaguilar6459 Good video..! I have 2011 Cascadia and l have similar issues my left and right turn indicators has a fast blinking and I have no front turn light communication signal. Could replace the Sam Chassis with a used one off another same year truck with buying a new one and having to get it programmed at the dealership?? Thanks

[@ariel0369]

Thank you. I have same issues and helps me to understand the root or at least in your case what was the root. I was suspecting to be sam chassis because also my abs module does not show but I hablé to check into that. Will see if sam chassis blinking lights may be also related to my wabco abs wont show alive within software reading. Checking that side now. Th aka again

[@robertv3802]

Quick question... I have the same problem. On the bottom Connector in the middle where you broke the clip, is the plug supposed to stay in there?? The yellow Connector??

My 2012 Freightliner Cascadia had this problem ⚠️ yesterday. I got back this morning and everything seems to work just fine. Should I still have the truck computer chassis replaced?

[@singhharjeet6154]

Hi n thank you for the video I have the sand issue, and I have you didnt have to reprogram the sam chaise right? U just replaced it.

[@oaguilar6459]

I did not have to.

[@stevenliberadzki9160]

I think its pretty important in this video to mention that before unplugging one wire the sam chass information needs to be exported so you can get that exact same information back when you put the next one in. Also you didn't buy a new one which has been updated through Detroit. The cover no longer snaps from the top. It screw on the bottom. Yes not exporting the data first leads to major headaches.

[@bilalmanzoor6313]

How do you export data using dddl

[@stevenliberadzki9160]

@@bilalmanzoor6313 I'd leave it to a professional. Why do you need to export the information from whatever module? First thing first is to make sure the correct Vin is showing. Delete any other vins showing. Many step to follow before, during and after when messing with the software.

@@TripleA3000 obviously you've never done this specific job. Or that wouldn't be your retort.

[@stevenliberadzki9160]

@@TripleA3000 freightliner, and others are a single Sam multiplexed systems. Programming isn't the same I wrench on all from ford to Hino. Not rocket science of course but it's a bitch when you brick a module. Having to re flash with origional software then updating to correct version. Like cummins we have bypassed the def header so then it's not the typical softwaresay just with the acm. You then have to flash all the modules. Usually a 6 hour process assuming all goes well. And shouldn't need instructions. If you need them you shouldn't be doing it.

[@stevenliberadzki9160]

@@TripleA3000 ya, freightliner updates their systems weekly. KZbin and Google gives you a rough. Did it tellyou the order of the modules to update or what to do with what fmi that populates when done out of order? Or just have a go and update a module and brick the hole system? Roughly $200 an hour to do programming a DD. Absolutely if someone applied themselves they may be able to do it. I've seen so many fail even with directions. Back to the point. The systems are not the same. Huge difference.

[@javierarreola6867]

My truck did have same issue reason last truck wash the put lots of water I. Ta area and burn Sam Chassi so it burn in few day due shorts it did with the contact of water

[@ER_666_]

I don’t know if you know anything about this bro but my side markers don’t blink anymore, I got power but not signal power you think is the sam chassis?

[@oaguilar6459]

Check the voltage with a multimeter if you get 5 or 6 voltage them you have a short circuit . But You can fallow the harness on the driver side turn signal. And see if you anything. You can also unplug the harness from the sam chassis. And check the voltage coming out of the sam chassis...

[@truckingwithcliff]

My side light would blink with key off and now my tail lights are staying on and tag light is out

[@makincash3337]

Did this fix it.

[@russeltollett6744]

Bro we’re are you located

[@bittusinghal21]

After replace the sam chassis need to programming or it can worked after just replace pls answer i have the same problem on my truck thanks in advance

[@oaguilar6459]

Yes you have to

[@henrypham3742]

Thank you for your help. I have a question. After changing new sam chassis, does it need reprogram.?

[@oaguilar6459]

I didn't have to program the one that used because I took it from another truck it's the same year so it had the same function. What year is your truck

[@henrypham3742]

My truck is 2012

[@oaguilar6459]

You have to program the sam chassis if its new.

[@ariel0369]

Yes you do if New. Dealer dddl only :(

[@johntu1723]

Did you had to reprogram it ?

[@oaguilar6459]

No cause i took it from another truck

[@gerardobarron551]

I have a freigliner cascadia the ligths are flashing when the truck is off I take to the mechanic and they can't find the problem

[@oaguilar6459]

If is flashing when is off check the main Fuses it depends on what year is your truck it will be on the firewall next to the engine fan solenoid or right on top of the batteries is a big fuse one of them is bad

[@gerardobarron551]

Is 2014 freigthliner cascadia
