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

There is no reset , if security light is lit there is a problem with the anti-theft system .Should have it checked for DTC'S - diagnostic trouble codes . Could have 8 different B - codes

You would need a professional type scan tool to read these type codes , not an OBD 2 code reader .

Check the input voltages to the ignition module. If they aren't what they're supposed to be, it's ECM or wiring fault. You need a wiring schematic to troubleshoot accurately on a problem like this.

Potential Symptoms

Most likely a P0011 DTC will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes

A P0011 DTC trouble code may be caused by one or more of the following:

• Incorrect camshaft timing
• Wiring problems (harness/wiring) in intake timing control valve control solenoid system
• Continuous oil flow to VCT piston chamber
• Failed timing valve control solenoid (stuck open)

Possible Solutions

This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.

The Cam Gear has a hole it it. That what GM uses for a mark.. Gotta love them young engineers at GM for improving an age old way of just putting a diamond mark on tooth instead. LOL
