My dealership told me they couldnt recreate the issue of sticking brakes. Code finally came up printed it immediately and found your video. Im sending this to my dealership ASAP!
@PhillipBailey nope! They ended up changing the steering angle sensor, clock spring. All the BS under the steering wheel. Brakes stopped sticking but the truck still goes in limp mode once and a while and my blinkers will stop. Gotta love advancetrack.
Can't believe I found this video, great troubleshooting steps, thank you so much. This is the exact problem I was having. Truck was losing vacuum (hard brake pedal sometimes), weird noise coming from wheel, turns out my right hub lock mechanism does not hold vacuum.
Glad it helped you but you're lucky to catch that particular leak with a smoke machine since it may have only leak under a vacuum. I usually check the vacuum actuators with a vacuum pump first right at the IWE nipple. If either does not hold a vacuum that gets repaired. Then I reconnect the lines and see if it holds vacuum now at the solenoid with a handheld vacuum pump. If not then the smoke come out to find the pinhole in the line. Thanks for the comment..
At 18:30 I found the hard plastic line leaking by the left front upper control arm bolt. I cut the line and slid a piece of electrical heat shrink over the plastic line. Heated with a heat gun and retested.
