I'm having a difficult time troubleshooting this code on my rover. It started out as something that would happen intermittently and restarting the truck was good enough to fix it. It got a little worse, so I replaced the brake light switch, and lights which gave me about another week before the same error code would come back. Now, the code is permanently on unless I'm on the brake
With the car OFF, brake depressed, the two circuits (Brake Lamp Switch and Brake Switch) both show "active". When I release the pedal, the Brake-lamp-switch returns to an "inactive' state and the brake-switch remains active. This causes the fault. At the same time, the shift-interlock clicks once to release when the brake is depressed but does not re-lock when, in park, and foot off the brake. I can shift freely without using the brake (again, because he circuit is "active").
all brake lights are fully functional and the issue does not go away when I remove the brake lights or change the bulbs. Reverse lights are functional as well. I've also tried swapping brake switches back and the issue remains. Something is up with the other circuit causing the ABS module to get a stuck "high" signal.
No fuse (ie f66) is blown.
I've found other reports of this which lead to a corroded or broken "red" wire but I'm not finding any of that. I'm also not seeing the link to be based on pictures and diagrams from others. I've scanned from the passenger side B-piller up into the kicker panel so far, along with a little behind the battery. Nothing appears broken, nothing is obviously rusted.
Could this be anything else?
