The other day i got in my c5 and the traction control said it was warming up. I this normal i've never had it say that before.

 

Fill in your profile when you get a few moments...... It helps to answer questions if we can see what part of the country you live in. Traction warming is normal in low temperatures. I believe something to that effect is in the owners manual. Hope this helps..........

 

I have this message on ocassion in cold temps, it goes off within 1 minute.

 

More than you probably want to know...

Active Handling Warming Up Excerpted from a 1998 SAE Paper; Chevrolet C5 Corvette Vehicle Dynamic Control System; Authored by Dick Hoffman and Michael Rizzo of the General Motors Luxury Car Group.

COLD AMBIENT - The thermal gradient of the engine compartment was measured at various ambients to establish the time it took for the hydraulic modulator to become warm and capable of full pressure response. When the vehicle is first started in cold weather and driven forward (>10 kph), the passenger zone module (PZM) monitors the engine intake air and coolant temperatures. The PZM contains software logic to determine if the hydraulics are cold <=-10C), and if cold, the cluster is instructed to display the message" Active Handling Warming-up". The system is functional but the first cycle performance can be affected until the next message "Warm-up complete" is displayed. Traction control and ABS actuations prior to Active Handling actuations will improve the cold hydraulic performance.

SYSTEM INITIALIZATION I SENSOR CENTERING
The yaw rate sensor and steering wheel angle sensor must be centered after each ignition off-on cycle. AH will not function until centering has occurred.

CENTERING - The steering wheel angle sensor is centered every ignition off-on cycle. This creates a more complex control algorithm but offers significant logistical advantages at the vehicle assembly plant and vehicle service centers. The Corvette assembly plant does not have to communicate with AH to assure centering. Service centers making repairs to the suspension, steering or replacing the steering sensor, do not have to communicate to the AH system. The AH system requires that the vehicle be driven while the system completes the centering routine.
The yaw rate sensor centers quickly if the vehicle is stationary or driven in a straight line. The yaw rate centering time increases with steering inputs >20 degrees or when the vehicle ignition is cycled to crank while the vehicle is moving.
The steering wheel angle sensor has a digital and analog signal output to the electronic control module (ECU). The AH centering algorithm uses the last "centered" analog value from the previous ignition cycle to quickly center the digital steering wheel angle value. The first ignition cycle at the car plant or after the ECU has been disconnected for several hours during service will require the longest time to center. The digital steering wheel angle value is put through a sanity check to make sure that the centering value is accurate. A sanity check requires driving the vehicle in a straight line after ignition off-on. The time for the sanity check increases with steering inputs .+-20 degrees.
INITIALIZATION - Under normal driving conditions the yaw rate and steering angle sensors will be centered and the AH system initializes within seconds after driving the vehicle forward. However, if for some reason, one or more sensors have not centered and the driver has exceeded 20 kph for a period of time, the PZM will command the DIC message displayed "Active Handling Warming Up", and a icon will be illuminated. This message can be acknowledged and erased from the display. When the centering conditions have been completed the next message "Warmup Complete" will be momentarily displayed, and the icon turned off. The system is functional. If the system never centers the "Service Active Handling" will be displayed.
