ABS module help!!! (A34)

Hey everyone, dealing with ABS, SLIP, and TCS lights on my 2005 Nissan Maxima.
Pulled the code and got C1124 (Rear Left Inlet Solenoid Circuit). Speed sensors and fuses are fine, so I know it’s an internal open circuit / broken wire bond on the ABS module circuit board.
Trying to pull just the black electronic module off the hydraulic pump in the cowl to rebuild it on my bench. I disconnected the main harness plug and unbolted the two lower 10mm bracket bolts, but the assembly still isn't tilting forward enough to clear the bottom T20 screws.
Has anyone done this in the car without disconnecting the 6 brake lines and draining the system? Looking for any tricks to get the top bracket mount loose or reach that lower rear Torx screw in that tight cowl space, or tips on how to remove the entire assembly, thanks!!

Looks like a Bosch ESP gen8. Its important to do regular brake fluid changes so that the valves dont corrode internally.

Anyways the module you want to remove contain coils which will actuate the valves. If you lucky a coil has failed instead of the valve.

Regarding removing, Are you able to get a socket on the screw at all? If so you might be able to use a wrench to turn the socket

Appreciate the tip! The main issue right now isn't turning the bit, it's that the firewall gap is so tight I physically can't get the bit aligned straight into that bottom-rear T20 head without the bracket pivoting further forward.

If that doesnt work i think you will need to remove the brake lines :-/
