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: Pontiac G6 ABS Problem
when the ABS light comes on you will not hear or feel anything cause soon as the ABS light comes on the ABS is disabled
sounds like it is weather related (rain,snow)
i would check both rear wheel speed sensor harnesses for water intrusion if you see any corrosion (green) on the terminals replace both the hub and harness
if there is no corrosion then check resistance of the sensor also check for a short to ground
if that is ok then put some dielectric lube on the wheel speed sensor terminals and clear the codes and see what happens
intermittent problems can be hard to find
hope this helps

The trouble codes are for the left front and right front wheel speed sensors. You should open your hood and in front of the engine on the drivers side under the air filter box you will see a silver tube shape object which is the air condition dryer. Look for your main wiring harness that pass near it. The harness can rub on the dryer and cause many different electrical problems including abs problems. If you see the harness rubbing on the dryer you can move the main wiring harness with your hand to see if there are any cut wires. If they are then you will need to repair the wires that are damage and reposition the harness to it will not rub anymore. This is a common problem with the pontiac grand prix.

when you changed the parts did you have the codes cleared ? as if the comp stored it then it will return and when you put new parts on it took the comp time to test and display new changes.

All most all of the chain auto parts stores will do a free scan and read your faults.
It is located close to the steering wheel under the dash.

Tips for a great answer:
Nov 22, 2016 | Cars & Trucks
Dynamic Rear Proportioning (DRP)
Traction Control System (TCS)
Vehicle Stability Enhancement System (VSES) (w/JL4)
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.
Brake pressure sensors--The EBCM contains 2 brake pressure sensors that monitor applied master cylinder pressure to the wheels. The EBCM uses the brake pressure inputs to enhance VSES.
Vent tube--The vent tube, located in the EBCM connector, 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.
Important: There is a rubber isolator located under the BPMV and on the mounting studs. The rubber isolators protect the BPMV and the EBCM from vehicle vibrations.
The BPMV contains the following components:
Inlet valves (one per wheel)
Outlet valves (one per wheel)
Master cylinder isolation valves (one per drive wheel)
Prime valves (one per drive wheel)
Wheel speed sensors (WSS)--As the wheel spins, the wheel speed sensor produces an AC signal. The EBCM uses this AC signal to calculate wheel speed. The wheel speed sensors are replaceable only as part of the wheel hub and bearing assemblies.
Traction control switch--The TCS is manually disabled or enabled using the traction control switch.
Brake pedal position (BPP) sensor--The EBCM receives a serial data message from the body control module (BCM) to indicate that the brake pedal is applied.
Yaw rate sensor (w/JL4)--The EBCM uses the yaw rate sensor to determine the rate of rotation along the vehicle's vertical axis. The yaw rate sensor is packaged with the lateral accelerometer as a single component.
Lateral accelerometer (w/JL4)--The EBCM uses the lateral accelerometer to determine the sideways acceleration of the vehicle. The lateral accelerometer is packaged with the yaw rate sensor as a single component.
Steering wheel position sensor (SWPS) (w/JL4)--The EBCM uses the SWPS as an indication of the position and rotation of the steering wheel.
This vehicle can set multiple DTC'S
DTC C0035-C0052 DTC C0111-C0120 DTC C0121 DTC C0131-C0139 DTC C0163-C0165 DTC C0179 DTC C0186 or C0187 DTC C0196 DTC C0220-C0229 DTC C0241 or P0856 DTC C0242 DTC C0244 or P1689 DTC C0252 DTC C0253 or C0254 DTC C0281 or C081 DTC C0460 or C0461 DTC C0550 DTC C0561 DTC C0870 DTC C0899 DTC C0900 DTC C1100 DTC C1101
Your best bet is to take it to a qualified repair shop ! You have no idea of the complexity of your vehicle .
