I have multiple messages in the display.. Service traction control, service abs, service stability control, check tire pressure, service steering..
This vehicle is equipped with the BOSCH 5.3 antilock braking system.
The vehicle is equipped with the following braking systems:
• Antilock Brake System (ABS)
• Dynamic Rear Proportioning (DRP)
• Traction Control System (ETS) (w/NW7)
• Traction Control System (TCS) (w/NW9)
• Vehicle stability enhancement system (VSES)
You need to have vehicle checked for DTC'S diagnostic trouble codes , do you know what they are ? The traction control , ABS an stability control are all a function of the electronic brake control system .It also seams the power steering is controlled by the Antilock brake system.The Magnasteer® is controlled through the ABS module and varies the torque by adjusting the current flow through the actuator.
Your best place to start would be to have ABS module scanned for DTC'S . Codes would point you in right diagnostic direction .
The following components are involved in the operation of the above systems:
• Electronic Brake Control Module (EBCM), The EBCM controls the system functions and detects failures.
The EBCM contains the following components:
- System Relay, The system relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves and pump motor.
- Vent Tube, The vent tube, located in the EBCM, is an opening to the internal cavity of the EBCM. It allows ventilation of the EBCM internals.
• Brake Pressure Modulator Valve (BPMV), The BPMV contains the hydraulic valves and pump motor that are controlled electrically by the EBCM. The BPMV uses a 4 circuit configuration with a diagonal split. The BPMV directs fluid from the reservoir of the master cylinder to the left front and right rear wheels and fluid from the other reservoir to the right front and left rear wheels. The diagonal circuits are hydraulically isolated so that a leak or malfunction in one circuit will allow continued braking ability on the other.

check all fuses and wires make sure everything tight.

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

If your trac and abs are both on. the problem could be a wheel speed sensor.
on some GM cars this sensor is built into the vehichles hub unit. making the bering and sensor one sealed unit. cheap hub units can be gotten (under 100 bucks) at autozone
SOURCE: I get intermittent ABS, traction control and power
Usually when I see this the problem it's related to one of the wheel speed sensors not giving the correct signal to the ABS system. A missing or faulty sensor reading will cause the ABS and related systems to turn off which causes the warning lamps to come on. The reason it works again once you have shut off the car is that the system resets and works until it sees the problem again. I would have the service codes read with a scan tool. Once that is done the problem is usually fairly easy to track down.

well this is a sensor problem. just cause you didnt get a fault code dome mean that the sensors are ok. Remove the abs Fuse from the fuse box under the hood. Drive the car and get a feel for the braking. Replace the fuse and drive again, you will notice one or more of the wheels dont hold as it fast or faster than the rest. Replace that sensor.
