Braking Problem - Solved

[Str8Shooter]

Still under warranty thankfully. Is this a common problem?




My blue driver scan tool shows the following codes:

C0506 - Right Front Wheel Speed Sensor Circuit/Open
U0554-00 - Invalid Data Received From Accessory Protocol Interface Module : No Sub Type Information
U0415-00 - Invalid Data Received From Anti-Lock Brake System (ABS) Control Module : No Sub Type Information
U0253 - Lost Communication With Accessory Protocol Interface Module : No Sub Type Information
C0034 - Right Front Wheel Speed Sensor : General Electrical Failure
U0415-86 -Invalid Data Received From Anti-Lock Brake System (ABS) Control Module : Signal Invalid

I see you have a 2021 like me. I did have many of the messages your seeing on my truck prior to updating all of the modules on my truck with FDRS last spring. You may have something more than a software issue there. But, question, is your truck fully updated in fdrs?

I've been getting updates regularly OTA. I got 3.5.3 dual phones, Android Auto Coolwalk, ec a few weeks ago. Just a few days ago I got some license light and trailer backup update.

I got a ton of codes when my battery went dead a couple months ago. May want to hook it up to a charger for a while, and see if it fixes things.

low voltage/bad battery?

I fixed the problem. It wasn't battery related. It was an open circuit just like my scan tool said. The fault code C0506 kept me focused on looking at the wiring harnesses close to the Right Front Wheel Speed Sensor Circuit both at the wheel and in the engine bay.

The cause was a rodent. I'm not sure what type, but if it comes back I will know...more about that after you see the damage. After I found the chewed wires at the white connector (see pic 2&3) I removed the connector, stripped back the wires and soldered some new wire to the existing wires, and wrapped it with electrical tape. All the errors on the instrument panel went away except the service engine warning light. Connected my blue driver scan tool and cleared the codes, which turned off the service engine warning light too.

Besides the fault codes it is very obvious in picture 1 a rodent was camping in my engine bay. Picture 2 shows that it also partially ate through my fuse box. I think the engine cover and the fuse box were nice warm spots for the rodent. Both spots now have mice glue traps velcro'd to them. I also added a mice glue traps Velcro'd on the drivers side engine bay along with a bag of moth balls wrapped in cloth in the engine bay near the drivers side headlight.

I'm assuming that I will either find mice glued to the traps or see a squirrel running around the neighborhood with a glue trap stuck to its foot.

Its also eating up your foam engine cover as well.

This is some impressive troubleshooting. Glad you solved it!
