I recently changed both rear calipers, rotors and brake sensor cable after driver side caliper was getting stuck tearing up the rotor. Job went smooth no issues, bled both calipers and refilled brake fluid. When I started it I had Engine, ABS, Brake light, Parking brake light, adaptive head light, HDC fault, transmission fault. Car drives and brakes fine. Parking brake engages and works. Height seems to be locked in low position.





I disconnected battery and it did not fix the problem.

 

Since you only worked on the rears, you may have also inadvertently moved/damaged the wheel speed sensor (ABS) and or one or both of the height sensors, one on each side of the vehicle, or you have a bad battery or alternator, or something else entirely. A quick peek at this YouTube video may also give you some ideas , these multiple error problems are not the easiest to diagnose, on my 2007 LR3 the brake pad light is always on because the detection circuit is open and I have not been able to find it, even though the cable sensor is good. I am sure others will chime in also with their thoughts, good luck...

 

The yellow brake light could be a disconnected fluid level switch on the master cylinder cap. Check that first. Or, it could be low on brake fluid. Check that second. Did you put the parking brake into service mode before you pulled the rotors? Did you adjust the parking brake shoes or adjuster in anyway? The parking brake tensioner may be at its limits.
HDC and transmission faults are related to the ABS system. How did you bleed the brakes? manually with a friend or did you use pressure from the master cylinder or vacuum from the calipers. If you changed the calipers chances are good you still have air in the system somewhere. try re-bleeding using the manual method first. If you have a GAP tool you can turn on the ABS pump which is most likely where the air is.
The headlight level warning light makes me think there is a height sensor out of limits. Did you move or bend one of those? Check the connections to make sure they are good.
The dynamic stability control lights may be related to a height sensor. (see above)

Just guess and as a general disclaimer: I might be wrong.

let us know what it turns out to be.
