ABS light on and Brake light on after brake job on 21' F150 V8 4x4. Bled the brakes properly (twice.) Tried using scan tools to get rid of but nothing. Will also turn on Advance Trac and Pre Collision warnings as well.
Anyone have any fixes to it? Could there still be air inside the abs system?
Everything was perfectly fine before the brakes change other than the pads of course.

 

What codes are stored and/or active in the ABS module? Did you put the truck into brake maintenance mode before starting the work? How did you bleed the brakes? Did you use ISO 4925 Class 6 DOT4 LV brake fluid? Did you have the battery disconnected or at a low charge at any point when the work was done?

 

These are the ones stored, yes they were bled twice just to make sure, and it was the done with the tube method into new brake fluid, yes on the fluid and the battery was not disconnected but maintenance mode was on while working on it

 

All the codes are common to the rear area.
Look for a rear harness plug-up issue, wet, not seated or damage of some sort.
They involve the Camera, ABS and a wheel Sensor. All separate functions but in the same the same harness.
Good luck.

 

I ran into the invalid data received code a couple months ago on a 2022 fleet truck we did a rear brake job on. We put the truck into brake maintenance mode and it wouldn't exit the mode. I tried 2 scanners (autel and snap-on) and forscan and spent a couple hours trying. We ended up towing it to the dealer where they fought with it and had to reflash it to clear. This may be your issue may not. Try re-entering maintenance mode clear codes, exit maintenance mode and clear codes. This was the second one in the last 5 years that fought us, the first one I was able to finally get working using forscan after a few hours, just make sure you have a battery charger on while trying to do this I've learned that when using IDS or any scanner programming it's better to be above 12.0v

 

What is a rear harness?

 

Does not the >>plug-up cable connection , wet, seated or damage suggest it is a wire group leading back to the rear area for all that needs power and control?
Read it again and see.

 

I saw very similar codes when trying an MY21 IPMA in MY23. (Never could get the camera to align either, maybe the level/RAS.) Appeared to be that IPMA power was off too long. I was just wondering what "rear harness" meant. I suspect maybe those codes may disappear with battery back to good SOC.
