Cascadia trouble codes

Ya, easy! I can help you out. Just as a side note, when quoting fault codes put them in the order of SA/SPN/FMI. For instance, 42/639/07

(i'm guessing on what these fault codes are per your numbers)
1. 254/14?--ABS ECU Mounting, Accelerometer not Plausible
You listed this one as a MSF controller, but cant tell exactly from your fault code

2. 42/639/??--No messages being received from data bus??
Your forward radar is having J1939 bus issues

3. 49/524037/31--Lost communication with CGW
You could have a CABINCAN issue

4. 11/3/05--ABS Wheel Sensor, Left Rear Second Axle - Open Circuit
Check connector to wheel speed sensor

These are all from my fault code cheat sheet--so they're not completely inclusive. My recommendation is to go back and verify exactly the SPN/FMI so I can get more accurate fault text.

 

Also, another thing. When you're listing out your vehicle, I see you listed Cascadia in the forum title. Next time list out the year/model/powertrain configuration. As example, 2008 Cascadia DD15 10 spd.

These will help get more people to understand your vehicle and respond appropriately and accordingly.

 

I had the same brake code turned out to be a loose abs sensor
