The Service Emission System (SES) is the main emission control device on your Duramax diesel engine. The SES monitors and controls the exhaust gas recirculation (EGR) system and the diesel particulate filter (DPF). If the SES light is illuminated on your dash, it means that there is a problem with one or both of these systems.
To clear the SES light, you will need to perform a manual regeneration of the DPF. This can be done by either driving at high speeds for an extended period of time, or by connecting a regeneration machine to your vehicle and running it for about an hour. After the regeneration process is complete, the SES light should turn off.
- Park the vehicle on level ground and shut off the engine
- Disconnect the negative battery cable
- Remove the emission canister purge solenoid electrical connector
- Remove the two bolts securing the emission canister to the bracket using a socket and ratchet
- Lift the emission canister out of its bracket and set it aside in a safe place
- Install the new emission canister in the bracket and secure it with the two bolts using a socket and ratchet

As the name implies, the service emissions system is responsible for keeping your vehicle’s emission levels in check. This system is made up of a number of different components, all of which work together to make sure that your car is running as cleanly and efficiently as possible. One of the most important parts of the service emissions system is the catalytic converter.
This component helps to convert harmful pollutants into less harmful gases before they are released into the atmosphere.
The service emissions system is typically serviced at regular intervals as part of your car’s routine maintenance schedule. However, if you notice any problems with your vehicle’s emission levels, it’s important to have the system checked out by a qualified mechanic as soon as possible.
Ignoring potential issues with your emission control system can result in serious damage to your engine and other components, so it’s always better to be safe than sorry!

How Do You Reset the Duramax Def System?
If your vehicle is equipped with a Duramax engine and you need to reset the DEF system, there are a few things you’ll need to do. First, make sure that the DEF fluid level is topped off. Next, locate the diagnostic port under the hood of your vehicle.
Once you’ve found it, connect a jumper cable from the positive terminal of your battery to the positive terminal on the diagnostic port. Finally, turn on your ignition and let your engine run for about 5 minutes. This will allow the system to reset and should clear any error codes that may have been triggered.
What Does Service Emission Light Mean?
The service emission light is a warning indicator on your vehicle’s dash that illuminates to let you know when the vehicle’s emissions control system is not working properly. The system is responsible for keeping harmful exhaust gases from entering the atmosphere, so it’s important to keep it functioning properly. In most cases, the light will come on due to a problem with the catalytic converter or oxygen sensor.
If you see this light, take your car to a mechanic as soon as possible to have it diagnosed and repaired.

Conclusion
If your Chevy Silverado 2500 HD or 3500 HD diesel truck is equipped with a 6.6-liter Duramax V8 engine, you may eventually have to perform a procedure called “regen” or regeneration. This is when the truck burns off built-up soot in the exhaust system by injecting extra fuel into the cylinders. The process takes about 20 minutes and can be done while you’re driving.
Here are the steps for how to clear service emission system Duramax:
1) Check your owner’s manual to see if regen is required for your particular model year and engine type. Some trucks don’t require it at all.
2) If regen is necessary, hook up a special diagnostic tool to the truck’s data port (usually located under the dash). This will allow you to monitor the progress of the regeneration process.
3) Drive the truck as usual until the diagnostic tool indicates that regen needs to start.
At this point, drive at moderate speeds on level ground until regen is complete (about 20 minutes). Avoid hard acceleration, heavy loads, and steep grades during this time.
4) Once regen is finished, check the diagnostic tool again to make sure it shows “complete” before disconnecting it from the data port.
