New Freightliner Cascadia (Fix Low Air Warning Light Stays on )

[@--s--]

Just FYI, the part numbers are backwards & a few digits off. Green = 12-26770-000 Blue = 12-26771-000 Thank you kindly for the video, it was a great help!

[@deanmoore1752]

12-26771-000 (the blue one) has been replaced by 12-31614-000 and requires a jumper adapter wire A66-23214-000

@@deanmoore1752of course it does 🙄 why are engineers idiots for? Making everything more expensive when an original fix was good enough? Good grief man.

Second time you saved me. First was the brake stop light switch. Thank you.

[@bigrigfix]

Thanks for watching.

[@keepersboy]

Oh yeah. The blue tagged one does seem to be the one for the brake drag function

[@rooseveltrainesjr7618]

Drain your air tanks everyday. U don't have to replace no air line unless you have a hole in it. My 18 cascadia was doing this from the first day I had it. An I bought mine brand new

Just did it it definitely took the beeping away just don’t like the part where it’s too tight and it’s hard to unscrew it. now i hear air leaking from that area. Any ideas what it could be?

[@bigrigfix]

The Abs light clear off when you go above 5 mph . If it’s still on after that there is something wrong.

[@TheBigfoottrucker]

Causes your fifth wheel not to unlock with the inside button also if their bad I believe

I’m not sure.

[@desvariosdeuncamionero8856]

I wanna know too if u found the issue please

[@Adoken101]

most of the time if you have any issue with Com. just do cpu hard reset. turn main cut off power switch down on driver side for atleast 15 mins and turn key to on position cycle 3 time and the 4 time start the engine.

[@scottwoughter7535]

Did that. Did not fix problem made it worse.

[@sammymaciel3876]

Theres a campaign for that

[@bigrigfix]

The switch are under warranty .

[@exilemike]

It doesn't work, you have to take the truck back to the dealer to hook it up to their computer to set the parameters for the system again.

I will never buy Freightliner junk.

Does anyone know if this is the same on a 2015... Cascadia... Same issue.. Low Air... Brake light...but no air loss..

I'm having that problem right now, and everytime it comes on the a/c stops blowing cold. Also that beeping is extremely irritating.. Thanks for the info ✌️

[@keepersboy]

Thanks so much. Was intermittent and getting worse. I did not have access to a new switch so just unplugged it. The default seems to be for it to be on. So I just ran a wire between the two holes in the plug and off... was driving me nuts

Blue tag part number is 12-26771-000 Green tag part number is 12-26770-000 I believe they are marked wrong in your video. Love the information though. Saved me down time at a dealership. Normally would take it in for the free warranty repair. But $80 out of pocket (both pressure switches) and a couple minutes of my time is better than a day of diagnostics. A day or two before they can "squeeze me in". No thank you. Again great information

great vjdeo

[@KOT-Grizzly89]

I currently still have to get tools for the truck as of now I cannot open that compartment. I’m not sure why I have a leak in my spring valves that apparently just came after I got done filling up and although my air pressure gauge is at 100, the emergency brake warning indicator is staying on I cannot figure this out.

[@orpheus1662]

Guys just Drain your air tanks you got water on them you should be good

Where can I buy those parts?

[@davidvalencia4895]

The blue tag is the drag brake switch

[@rujansiwakoti9921]

What is the part nm

[@dieselfixr]

I have to say thank you!!!!. I been a diesel tech for the passed 5 years. I knew the issue was a pressure sensor but the oem manual doesn't say which one. It just saids to replaced it. Lol. But I do know what the green sensor does. It's a 2 part system. The green sensor is part 1. Normally close switch when the yellow brake valve is pushed in the switch opens at 9-12psi that tell the ecm the parking brake is being released. Part 2 the blue sensor is a Normally open switch is closes at 73-83 psi and that tells the ECM the parking parked is Fully Released. So anything below 73 psi the warning chime and low air pressure light comes on.

[@ravshana]

Would mixing up the cables on these switches can give ‘low air beep signal’ on dashboard ? And which switch would it be for that error?
