Which indicator light are you going by to say the TC is not on?
Are you reffering to the led in the TC switch itself or are there any other indicators on the dic (ie service stability system)?
First you should have the car scanned for any dtc'* if there were a problem with the EBCM then a code would have been set.
The book reads the only 3 things can turn off the tc light
dtc set by the ebcm
driver turned off the switch
bulb burnt out
btw: The EBCM is located under the hood on the drivers side, in front of the radiator on the lower cross member. It is a large aluminum block with brake lines and a connector to it. Make sure the ignition is off before removing this connector.
