HDC relies on the data from the ABS sensors also, so you should check the ABS sensor cables and that the sensors have not been disturbed (the cables run close to the brake wear sensors). I would bet that they have either disturbed or disconnected the ABS sensor or damaged the cable. It could also be a possibility that they disconnected the sensor, ran the vehicle then realized that it was disconnected, but the fault was triggered, and it may be a case of just having to reset the ABS or HDC system to clear the fault. To reset this fault requires Testbook/T4 or a non-oem software/hardware.

Air Suspension Inactive usually means there is a problem with the Air Suspension. However, it will also come up when alternator or battery voltage is low, or when you reset (disconnect and then connect) the battery. To reset it manually: while in P(ark), turn steering wheel all the way left, hold few seconds, and then all the way right, hold few seconds. All the warning lights will go out. Most common failure is the passenger front air strut, since batteries are prone to leaking acid, it leaks right on top of the rubber airbag and burns through it. Dealer willcharge you one hour to diagnose, or you can easily diagnose this by looking at the ride height of each particular corner of the truck. If its sits low, or emits hissing sound when you park the truck, its leaking. If you keep driving with leaky air strut, you risk burning up the air compressor, as its working extra hard to compensate for the leak. Replacing the strut is easy 45min job even for a novice mechanic, and you can do it yourself. Strut can be found new for approx $750 online. If you are fed up with air suspension issues, there is a $700 kit that converts the truck to springs, and disables all of the air suspension. Look up Arnott Industires

I'm also looking for a 2008 RR Sport manual. I was told that they only come on disks now and getting a replacement would cost $150...

Hello! Regarding the battery...The voltage regulator (inside the alternator) is faulty...It can be tested at any major auto parts store...
Lets talk about the fault lights...There were no fault lights before you changed the battery and appeared immediately after the new battery was installed; Or was there a time lag between the two events?
The trouble lights mean there is a problem with one or more of the sensors that monitor
wheel rotation...With that malfunction the anti lock brakes and the hill
descent control are disabled...Take the vehicle to a dealer or a
specialist with the T4 or Auto Logic system and have them read the faults...You will not be able to access those
systems with a generic OBD II scanner... More than likely the culprit is a wheel sensor...
