Hello, I drive a 2018 International LT Automatic. There seems to be a strange computer or electrical issue with this thing. An indicator light comes on saying Check ABS, then check transmission, then traction control comes on. It’s been in the shop in three states and they can’t figure it out. The codes it throws are as follows:
S.A. 3 SPN 563 FMI 14 OC 127
S.A. 11 SPn 639 fmi 2 Oc 127
S.A. 33 SPn 597 fmi 0 oc 12
It’s intermittent and seems like letting off the brakes can trigger it when it’s acting up. If I leave the truck run a while sitting still it goes away most of the time. Very strange issue. My cousin is a diesel mechanic and said one of the codes references the trucks network so it could be the way the obc was installed? Any help would be appreciated and if you need more info just ask and I’ll find it.

Also... while sitting still if I press the brakes it can trigger the errors. Then they go away after a while of sitting. It happens a few seconds upon removing my foot from the brake pedal.

You likely need a new brake switch. The brake switch is a smart switch and the body controller tells the trans and abs when you are braking. SA 3 is the trans, and SA 11 is the abs and those codes are specifically for communication problems only related to the hill start aid which is used when the trans it at an angle and thinks you are on an incline and uses the abs to help with holding your position and starting from neutral. The abs is also showing a code for not getting the right message at the right time and I believe this is because SA 33, which is body controller, is not sending the brake switch message because it is logging a faulty switch code.
