2006 chevy Tahoe 5.3 flex fuel brake pressure modulator valve assembly leaking rusted out. Like 5 different part numbers on alldata. With and without luxury edition. With jl4 without jl4 which is active brake control. The truck has traction control. Is there a way to look at rpo codes and which ones to find out information to get correct part number? Also have to bleed all wheels and master cylinder and use a scan tool to do an automated bleed on new brake pressure modulator valve assembly. Thanks for any input.
Checking RockAuto, it looks like ACDelco #19149234 is for RWD without Active Brake Control, or RPO JL4. #19122463 is for trucks with JL4, transfer case RPO's NP8 or NR3, or tire option QSS.
