2006 G6 GTP Convertible......cruise won't engage, traction light stays on
Fix the problem with traction control first
How do you know brake pedal positioning sensor needs to be replaced ? Traction light on ? DTC'S - diagnostic trouble code's stored . That's why cruise won't engage . Taking your vehicle to a qualified repair shop an having it diagnosed is what you should do.
Cruise Control Inhibited
The engine control module (ECM) inhibits the cruise control operation when any of the following conditions exist:
• The ECM has not detected a brake pedal activation from the body control module (BCM).
• A Cruise Control System DTC has been set.
• The vehicle speed is less than 40.2 km/h (25 mph).
• The vehicle speed is too high.
• The vehicle is in PARK, REVERSE, NEUTRAL, or 1st gear.
• The engine RPM is too low.
• The engine RPM is too high.
• The system voltage is not between 9-16 volts.
• The Antilock Brake System (ABS)/Traction Control System (TCS) is active for more than 2 seconds.
Do the stop lamps work ?
DTC P0703 Brake Switch Circuit 2
The body control module (BCM) monitors the brake pedal position sensor. When the brake pedal is applied, the BCM detects a predetermined voltage signal. The BCM sends a GMLAN serial data message to the powertrain control module (PCM) indicating the status of the stop lamps.
DTC P1574 Stop Lamp Switch Circuit
The stop lamp switch signal circuit is a direct hardwire input to the throttle actuator control (TAC) module from the body control module (BCM). The TAC module monitors the stop lamp switch signal circuit in order to detect when the brake pedal has been applied. When the brake pedal is pressed, the BCM sends a GMLAN serial data message to the powertrain control module (PCM) indicating that the brake pedal has been applied. The BCM also sends a high voltage signal on the stop lamp switch signal circuit to the TAC module. The TAC module sends a universal asynchronous receiver transmitter (UART) serial data message to the PCM indicating that a brake pedal application has occurred. The PCM will compare the UART serial data message and the GMLAN serial data message in order to confirm that both serial data messages match.
SOURCE: ABS light and Traction control light stay on.
That "grindy" feeling is when the ABS kicks in. It's only suppose to activate when you slam on the brakes and the wheels would normally lock. Instead, ABS will very quickly pump the brakes on and off, to prevent the wheels from locking (making a giant skid mark) and stopping the car more effectively. Generally this only happens if you slam on the brakes or loose traction due to rain or snow while braking. If this is happening often and the brake light is on, on the dash, then you need to get this checked out by a qualified mechanic ASAP.

check the sensors and connections may have loosened or knocked one loose if they look ok than have truck scanned most auto stores such as auto zone/advanced auto scan for free the trouble code will narrow the problem
SOURCE: I have a 2006 G6
There are many reasons for the light to come on example: tire pressure not same in all tires, tires of diffrent size, ABS sensor wire loose or cracked. The best thing is to retrive the code which will tell you exactely what and which VSS vehicle speed sensor is failing.

The traction control and transmission shifting would involve the body computer more so than the engine computer.
Have you had the body computer scanned for trouble codes ?
