Codes that light check engine lamp are emissions/engine performance related only. Your DRL and SDM both talk to the ECM for inputs (they need to know if its running), but they dont affect the engine or tell the engine module to change how it runs.
Your ABS can affect how the engine runs as it sends wheel speed information that is used to adjust engine output, transmission shifting, and fuel/timing in some circumstances.
Check the ABS module for signs of water or oil affecting it, or water in the connector plug. Also check the harness where it leaves the module to make sure it isnt rubbing thru anywhere you can see.

GM ABS modules are not uncommon failure items, however mostly they set module fault codes or motor amperage/function codes. Id start with further diagnostics of the ABS.

NOTE: using generic OBD2 scan mode will show you only codes that are check engine lamp related if you want to be sure. Enhanced scan mode shows you any and all, and some of them simply have nothing to do with the engine lamp being on.

Hi:
You should first check the level of the coolant in your radiator first thing, when your engine is cool. If it is low, add some coolant and check for leaks.
Next, take your vehicle to a local auto parts store, such as autozone, and they will scan your vehicle codes for free, and tell you what is causing the check engine light and ABS light. You can then decide what is up and what needs fixed first on your car.

Are there any indication lights on? For Example, check engine light, low washer fluid light, abs light. If any of those are on afetr the car has turned on, that could be the case.

Have the DIS module checked and the coil pack for cyl 3. If either/both of those need replaced, have it done and have the codes cleared. Then see if it clears the others.

You may need a TPS (throttle position sensor) as well.
