How do I reconnect the front brake lines to the brake control module? Which lines go where?

This is mounted on the anti lock brake block that the brake lines come out of that module controls the anti lock brakes air suspension and traction control

Your best bet ! Take it to a quaified repair shop . Do you know what Class 2 data bus is ?

Class 2 Serial Data Line
The class 2 serial data line on this vehicle is a star configuration. The following modules communicate on the class 2 serial data line:
• Audio Amplifier, w/UQ7 and Y91
• Body Control Module (BCM)
• CD Changer (CDX), w/U1S and Y91
• Digital Radio Receiver (DRR), w/U2K or U2L
• Driver Door Module (DDM)
• Driver Seat Module (DSM), w/AN3
• Electronic Brake Control Module (EBCM)
• Electronic Suspension Control (ESC) Module, w/Z55
• Front Passenger Door Module (FPDM)
• Generator Battery Control Module (GBCM)
• HVAC Control Module
• HVAC Control Module - Rear Auxiliary
• Instrument Panel Cluster (IPC)
• Powertrain Control Module (PCM)
• Radio
• Rear Seat Audio (RSA) Controller, w/UK8
• Rear Seat Entertainment (RSE) Assembly, w/U42
• Rear Wheel Steering Control Module (RWSCM)
• Inflatable Restraint Sensing and Diagnostic Module (SDM)
• Transfer Case Shift Control Module (TCSCM), w/NP1/NP8
• Vehicle Communication Interface Module (OnStar), w/UE1
• Vehicle Theft Deterrent (VTD) Module, w/VD1
The class 2 serial data line allows a scan tool to communicate with these modules for testing purposes, checking for DTCs, and to activate/enable/disable functions. These class 2 serial data circuits are bused together via three splice packs and DLC:

Jesse, The module will not stop fluid to rear brakes, a bad master cylinder will,leaking lines, air in brake system, faulty metering block if equipped, collapsed flex lines or pinched brake line faulty caliper or brake cylinders,etc. will cause the possible feeling of no rear brakes.
(ABS Module components) the ABS speed sensors and the ABS control module . When the brake is applied, the ABS control module reads the speed data from the speed sensor and sends the correct pressure to each wheel to prevent any wheel lock up, eg. sliding/skidding Links below have more info.

One of the modules may be doing it , interior light lit -glove box ! Hard to say on newer vehicles , after 1996 ! You vehicle has some of these modules if not all !

The way to find the drain on the battery is to do a Parasitic Draw Test ! I'll send a link for Eric the car guy !
How To Perform Parasitic Draw Test EricTheCarGuy

Off the master cylinder. The front tube controls the rear brakes. And the back one controls the front brakes. Just a note. I don't know which year they started doing this, but, the front right brake goes/ties in to the left rear brakes. left front to right rear. This set up runs off the ABS module to the brakes.

speed sensor is on right side of transaxle just above where right axle shaft go's into trans . if the speed sensor is at fault your speedometer will not work and your ses light shoulded be on .check if your brake lights are working . brake switch could be faulty . disconnect the cruse control cable at throttle and at cruise module (left shock tower) to see if pull ribbon in module is broken . other than that you need to start doing electrical tests at the module

Best case scenario bad vacuum pressure to the brake booster. Worst case bad abs control module or valve body/motor the abs system works by add and removing hydraulic pressure through valves and electric motor. Try using block off plugs at the master cylinder( remove lines plug outlets at master cylinder) check if brake pedal position and pressure is good(if there is no change problem is master cylinder or brake booster/ vacuum) if plugging at master cylinder solved issue repeat procedure at abs valve body after reinstalling lines from master cylinder if your problem returns your issue is in the abs valve body if plugging at the abs solves problem reconnect at the valve body bleed each line one by one testing between each line until you find the problem

{: ) The ABS/TCS module (or the Electronic Brake Control Module- EBCM ) is located at the front left lower corner of the engine compartment, under the air cleaner housing. The EBCM is attached to the brake pressure modulator valve. See sample diagram:


1. secondary air injection
2. Electronic Brake Control Module
3. brake pressure modulator valve

YOU NEED A SCAN TOOL TO BLEED BRAKES.THE SCAN TOOL REACTIVATE HYDRALIC BRAKE MOTOR.YOU CAN RAISE VECHICLE WHEELS OFF GROUND SUPPORT SECURE SAFELY. ALLOW DRIVE WHEEL SPIN 5 MILES AN HOUR WHILE VECHICLE OFF GROUND THE WHEEL SENSORS WHILE WHEELS SPINNING WILL ACTIVATE ABS HYDRALIC MOTOR TO BUILD UP BRAKE FLUID PRESSURE.THEN LOWER VECHICLE TO GROUND.MAKE SURE MASTER CYLINDER BRAKE FLUID LEVEL CORRECT THEN BLEED BRAKES IF BRAKE DONT FEEL FIRM OR SOLID DONT DRIVE HAVE VECHICLE TOWED IN.GARAGE WILL HAVE TO USE SCANNER TO BLEED BRAKES.

Hello,
I hope this helps.
