have truck scanned for code can be simple as a sensor to hub problems

First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

Get a computer diagnostics done and it will likely tell you what is wrong. You can buy readers now for less than $100.00. Otherwise you are really guessing.

Traction Control Off Indicator The IPC illuminates the traction off indicator when the following occurs.
?€¢
The EBCM disables engine torque reduction due to a malfunction and sends a serial data message to the IPC requesting illumination.

?€¢
The driver manually disables VSES and engine torque reduction by pressing the traction control switch. The EBCM sends a serial data message to the IPC requesting illumination.

Since all three systems work together, when the engine light is on the other two can be also.
I would start with checking the engine computer for trouble codes.

please scan the ECM for codes and post them

So the equinox is the same as a 2008 Suzuki XL7?????

how do you fix the "reduced engine power" light on the dash bard of a 07 Chevy Impala LTZ and "Service Traction Control"?
