My 2021 Ranger is giving me error messages

[Jim Oaks]

I drove off of a curb pulling out of a parking lot and the Ranger started flashing these error messages:

Service AdvanceTrac
Pre-Collision Assist Not Available
Terrain Management System Fault

As well as the ABS and Traction control lights.

Anyone have any suggestions on how to fix it???

Drove less than a mile home, shut it off, and turned it back on. Still there.

Scanned for codes - no codes.

I used a scan tool and didn't get any codes, so I hooked up forscan and got the following DTCs:

PCM: U0422:00-2F (diagnostic trouble code that occurs when the other control modules on the vehicle are not communicating with each other)
PAM: UO415:00-2B (invalid data received from the ABS control module)
FCIM: B113C:11-48 (can't find a definition)
ATCM: U3000:49-08 (The module has permanently disabled an output because an excessive current draw fault (such as a short to ground) has exceeded the limits that the BCM can withstand)
ABS: C0037:65-C8 (Left Rear Wheel Speed Sensor: Signal Has Too Few Transitions / Events)
PSCM: U0415:00-08 (Invalid Data Received from Anti-Lock Brake System (ABS) Control Module)
IPMA: U0418:86-AF (Invalid Data Received From Brake System Control Module)

After looking at all of that it looks like I need to check my left rear wheel sensor.

Loose connection or bus line....or loose or crushed sensor...cracked magnet...
Slightly worn wheel bearing..

Well ABS and Traction control are used together, and pre-collision assist is ABS as well

Because of the "bump" I would unplug and plug back in ABS modules connector
Reset all codes then drive

C0037:65-C8 (Left Rear Wheel Speed Sensor: Signal Has Too Few Transitions / Events)
This means the sensors pulse count doesn't match previous pulse counts for speed
Its questioning the "sanity" of the sensor, doesn't say its not working
May be just unplug it as well and plug it back in

 

[Jim Oaks]

Ya, I'm really hoping it's just a loose connection issue. Especially since it happened after going over a bump.

I unplugged the left rear wheel sensor, plugged it back in, and then used forscan to reset the DTC's.

Drove around town for a little bit and didn't get any more messages. We'll see what happens.
