If your truck is a 2004.5-2005 model year and it has the Duramax 6600 engine, then it’s equipped with what’s called the Service Emission System (SES). The SES light will come on when there’s a problem with the system and needs to be reset.
- Check the service manual for your specific vehicle to locate the emission system
- Disconnect the negative battery cable
- Raise and support the vehicle according to the service manual instructions
- Locate and remove the emissions system fuse or relay
- Start the engine and let it idle for several minutes
Service Emissions System See Owners Manual 175 Mph Until 65 Mph Max
If you’re looking to keep your car emissions system in top shape, be sure to follow the owner’s manual. For service and maintenance, it is recommended that you take your car to a professional every 25,000 miles or so.
How Do I Reset My Service Emissions?
If your car is due for a service emissions test, there are a few things you can do to reset the system and ensure a passing grade. First, make sure your gas tank is at least half full. Next, disconnect the negative battery cable for 30 seconds to reset the system.
Finally, drive around for about 15 minutes to allow the system to recalibrate. If you follow these steps, you should have no problem passing your service emissions test.
How Do You Reset the Duramax Def System?
If your Duramax diesel engine is equipped with a Diesel Exhaust Fluid (DEF) system, you will need to perform a DEF system reset at certain maintenance intervals. The DEF system reset procedure is simple and only takes a few minutes to complete.
To reset the Duramax DEF system:
1. Start the engine and let it idle for a few minutes to warm up. 2. Locate the DEF fill port on the side of the vehicle (it will have a blue cap). 3. Remove the cap from the fill port and insert the funnel.
Slowly pour 1 gallon of fresh DEF fluid into the fill port until it reaches the full line on the funnel. Replace the cap when finished. 4. Turn off the engine and wait 5 minutes before restarting it.
TheDEF system reset is now complete!
What Does It Mean When It Says Service Emissions System?
A service emissions system is a system designed to control and reduce the emission of pollutants from a variety of sources. The most common type of service emissions system is the catalytic converter, which is used to convert exhaust gases from internal combustion engines into less harmful substances. Other types of service emissions systems include diesel particulate filters, selective catalytic reduction systems, and lean NOx traps.
Can I Drive With Emission Problem?
If your car has an emissions problem, you may be able to drive it, but you may also be breaking the law. Check your local laws and regulations to see if driving a car with an emissions problem is allowed in your area. You may also want to get the problem fixed before driving, as it can lead to higher emissions levels and decreased fuel economy.
GM Duramax: “Service Emissions System” but no DTCs??
If your Chevy Silverado or GMC Sierra Duramax diesel truck is having trouble starting, idling rough, or throwing a check engine light related to the service emission system, there’s a good chance that it just needs to be reset. Here’s a step-by-step guide on how to do it:
1. Start by disconnecting the negative battery terminal.
This will help prevent any accidental electrical shocks. 2. Next, locate the fuse box under the hood and remove the fuse for the ECM/PCM (engine control module/powertrain control module). 3. With the fuse removed, start the truck and let it run for about 5 minutes.
This will allow the ECM/PCM to reset itself. 4. Finally, replace the fuse and reconnect the negative battery terminal. Your truck should now be running smoothly again!
