CAT C15 MXS Jake problem

Hello there .
Need some help with my '06 CAT C15 Acert MXS as I really feel I'm ready to set this thing on fire
The problem is that when it's getting cold outside (about 35F or below) the cruise control and Jakes stop working . Will start working again if I stop and idle for 10-15 mins but will only last 5-10 miles and it dies again . If it's about 40F or above works fine with no issues at all .
No check engine lights , no codes , no nothing .
Maybe somebody had the same problem before and can share some knowledge , thanks .

 

yours would not work only in cold weather too ?
I've checked the fuses and connectors to the swithes (ON/OFF and position) and they seem to be OK . How do you think , a bad switch or fuse would cause the issue or it might be a bad sensor ?
I also had to mention that I replaced the speed sensor on the tranny , had a friend of mine with exactly the same problem on an ISX and that fixed his problems , however , it did not change anything for me .
I've done some research on a lot of forums and I've seen plenty of different opinions .
However , went to a dealer yesterday and they found out that the throttle pedal is out of calibration and I'll need a new sensor .
I've been having the jake issue since last winter but back then it was not throwing any faults for the pedal .
Can it be that the engine is not reading the correct coolant temp (bad coolant temp sensor) and will not let the jakes kick in ?
The intake air temperature sensor going bad might be an option too ?
Thank you

 

what do you mean by something to do with the driver lol?

 

sorry for asking but what the drive collaboration means ?

 

will go to the dealer tooday to get the switch , should I get both of them ? (ON/OFF , position)?
