Code 48 appears with the 93 Allante. It says EBTCM modular problem or a Brake pressure modulator, Information center on car says Traction disabled, abs disabled and low brake fluid The red brake light comes on while driving.but the reisvoir has fuild just below the top. What do think I need to do

traction control light on . DTC'S - diagnostic trouble codes are stored in ABS control module pointing to the malfunction . Take to a qualified repair shop or to auto part store that can pull these code. DTC C0242 00: Engine Control Module (ECM) Indicated TCS Malfunction
DTC P0856: Traction Control Torque Request Circuit
The electronic brake control module (EBCM) and the engine control module (ECM) simultaneously control the traction control. The EBCM sends a serial data message to the ECM requesting torque reduction. When certain ECM DTCs are set, the ECM will not be able to perform the torque reduction for traction control. A serial data message is sent to the EBCM indicating that traction control is not allowed.

Traction Control Off Indicator
The IPC illuminates the traction off indicator when the following occurs.
• The EBCM disables engine torque reduction due to a malfunction and sends a serial data message to the IPC requesting illumination.
• The driver manually disables VSES and engine torque reduction by pressing the traction control switch. The EBCM sends a serial data message to the IPC requesting illumination.

PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Check harness routing; pay particular attention to wheel speed sensor wiring harness routing. Check fuses No. 1D, 5B and 6B in instrument panel fuse block. Check fuses No. 1 and 2 in underhood fuse block. Check brake fluid level in master cylinder reservoir. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Ensure parking brake is fully released. Ensure parking brake switch is functioning properly. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. See Fig. 5 .If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. See Fig. 5 . The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds. During self-test, EBTCM commands TRACTION OFF indicator warning light on. Powertrain Control Module (PCM) can also command EBTCM to set a Code 75 which will illuminate TRACTION OFF indicator.Traction control switch is located either on instrument panel center trim plate or driver's front door trim panel. Switch allows driver to select traction control mode (on/off). When traction control system is turned off, TRACTION OFF warning light comes on.EBTCM monitors transaxle temperature through

hi. does this sound familiar.

Anti Lock Brake System (ABS) problem. Has trouble code C1243.

1. Pin test power and ground to the Electronic Brake Traction Control Module (EBTCM).

2. Stress test the power and ground by using a high beam headlight or blower motor to put a load on the system.

3. If power and ground are OK, remove the EBTCM and hot wire the pump motor. If it runs OK and is quite, replace the EBTCM. If the motor is noisy replace both the Motor and the EBTCM.

Brake Pressure Modulator Valve (BPMV) - BRAKE PRESSURE MODULATOR VALVE WAS NEEDED

Too major for this forum - you probably should research the code online.
It involves a pressure switch in the EBTCM ( electronic brake control model ) not reading the right voltage signal.
It could be a wiring problem or a faulty sensor which could require having the EBTCM rebuilt.
The active steering - traction control uses the brakes to keep the wheels from spinning or skidding.

That means that the EBTCM has detected a problem within the system.The message indicates that a malfunction exists in the stability enhancement feature.

EBTCM (Electronic Brake and Traction Control Module) is an electronic control module that controls and operates the Anti-Lock brake system, Traction Control System and Stability system. If this module detects a problem, it "asks" the cluster to inform you by displaying a warning message.

You should have your car scanned for trouble codes with a scan tool, the Tech2 scan tool is preferred because other scan tools may not communicate with the EBTCM modules.

Hope helps (remember to rate this answer).

An Electronic Brake Control Module, or EBCM, monitors the rotation speed of each wheel. The EBCM decreases the braking force to a wheel when it detects that the wheel is rotating more slowly than the other wheels. Additional details for GM vehicles in this link: absfixer.com/how_do_i_remove.

EBTCM is the Electronic Brake Traction Control Module device.

Good luck.

BPMV = Brake Pressure Modulator Valve.

Part of the anti-lock brakes and traction control system.
The BPMV is located at the left hand front corner of the engine compartment, attached to the EBTCM (electronic brake control module).

CAUTION: For safety reasons, the brake pressure modulator valve assembly must not be repaired, the complete unit must be replaced. With the exception of the EBTCM ,no screws on the brake pressure modulator valve assembly may be loosened. If screws are loosened, it will not be possible to get the brake circuits leak-tight and personal injury may result.

The C1214 error is related to the electronic brake traction control module (EBTCM) BPMV pump motor relay contact circuit open. Check the 40A ABS Maxifuse in the underhood electrical center. if blown change it, clear the DTC and if it blows again check for a short in the 1642 line or internal short in the BPMV.
When an ABS/TCS operation is required, the EBTCM activates the pump motor relay and battery power is provided to the pump motor. DTC errors are either H (history) or C (current) I usually clear the history and see if it sets again later.

It sounds like an ABS sensor or some other sensor going out. IF it's the main computer for the traction/handling system that's big $$$$$ like $1300+ I think.
This problem frequently starts out as occasional, goes to frequent, and then full time.  It usually relates to the ABS/TC assembly on the frame in front of the engine. 
It is made of two parts, the EBTCM (the electronic part) wich is bolted to the mechanical half, the BPMV (Brake pressure modulating valve.) Sometimes the electronic grounds for this assembly get corroded or loose. Bad connectors for the ABS speed sensors at each wheel hub can also go bad.

Good luck and hope this helps.
