2023 Cascadia Rain Issue

You need to know what codes are being thrown. Check the wiring for the wheel speed sensors.

 

Get the same with bendix on my 22 Pete. Been thru two modules. They tend to take in moisture.

 

check truck diagnostics codes, a bad wheel sensor will make all those things stop working at the same time, the SPN FMI codes will tell which sensor it is. mine got confused in the wet a few times, cleared itself after a few days. then months later in the cold wet, raining as the sun went down and temps dropped below freezing, ice jacked the sensor permanently, lost ABS, hill start, traction control, and trans wouldn't work in auto, had to use manual mode, flashing F. just the front curbside wheel sensor was bad, fixed everything.

 

I had similar symptoms. Turned out water was getting into the ABS connector. The wheel end sensor is only so long, then it plugged into an extension wire that took it to the abs module. When I pulled apart the connector it was green inside. I replaced both the sensor and the extension wire.

 

I've had it come back a few times, twice, both times right after I had the wheel hard jacked to the left for an "maneuver".

I read something somewhere about a 'tone wheel' that can get very slightly bent.

I also think the metal tube with a slit in it that holds the sensor is maybe loose, I tapped on the sensor and it moved back in a little deeper in its tube, restarted truck, lights all gone. front curbside steer sensor. same lights, tap tap, same fix.
