I have a hunch it might come back on.
When we lost the line going to the rear, I bled the system using the tube into the jar of brake fluid and ran a lot through. I was at the point of no bubbles, just good clean fluid pushing through. Additionally, I always end up with the 2 person method of pump up the brakes, hold them, release the pressure and tighten the bleeder while the brake pedal is still depressed.
Intermittently, that warning came on. After I did the the remainder of the lines and had the system bled at a dealership, the warning has not returned.
From the research that I did, we can get them close by taking them out on a gravel road and stomping on the brakes to get the ABS unit to kick in,
the ABS unit will never be entirely flushed of air without the use of a Tech2 to cycle the valves.
Be prepared to use a few quarts of brake fluid. All together, my truck took 5 quarts, 3 I used and 2 the dealership used, to get all the air out.
The Russell braided lines have made the system better than when I bought it.
These trucks can also get a bit of corrosion under the ABS sensor seat on the front wheels. You clean the seat and re-install and that will sometimes clear up some errors as the sensor gets pushed too far away from reading the magnet.
