Just like the title states, upon start up nothing happens. The starts fine, shifts gears fine until I hit about 10mph. Then the LR3 makes like a grinding sound and brake pedal pulses which sets the errors on the dash. HDC Fault, Special systems unavailable, suspension lowered and amber brake light stays lit. I've already changed the brake switch and all of my brake lights work. Also, when the errors come up, my tranny doesn't shift beyond 3rd gear. Manually I can change gears.

Any thoughts, ideas?

 

 

Without fault codes definitely tricky to diagnose. With the pulsing brake pedal, I would suspect an ABS sensor ring or other ABS related issue causing the vehicle to go into limp mode.
