I have a 2005 XJ8. It was in limp mode and I was getting P2135. I tried to replace the TPS and it didn't fix the problem so I had to replace the throttle body. I also replaced the battery. The car was without a battery connection for a couple of days while I waited for the throttle body to come in.

I have installed the throttle body and battery and the car is running again, no codes except the "All OK" P1000. However, the Park Brake Fault is on. Is this something that just needs to be reset or calibrated, or is there something specific that I should be looking for?

If it's just a reset can anyone give me steps to reset it?

 

In principle, the parking brake (as well as radio code and electrical windows) has to be recalibrated once you disconnect the battery.
The procedure is straightforward, here under copied from DonB, as often

"Your Electronic Park Brake (EPB) problem may be solved by a simple reset. There are two or three procedures outlined in the Workshop Manual for restting or calibrating the EPB. The short version is this:

Disconnect the negative battery cable for 30 seconds
Reconnect battery cable
Start the engine
Watch for a message below the speedometer that reads Apply Brake, Apply Foot and Parking Brake, etc.
Firmly press and release the foot brake pedal 5 times
While lightly depressing the foot brake pedal, activate the EPB in both directions, On-Off-On (Up-Down-Up)

If all is well you should have no brake-related warning message remaining. If the PARKBRAKE FAULT message appears, you will need to try the longer calibration procedure."
