What You'll Learn
Kenworth T680's auto start/stop feature saves fuel and money
Kenworth's Auto Start/Stop feature is an innovative solution for owners of the company's T680 trucks, offering significant fuel savings and cost reduction. This smart functionality automatically shuts down the engine when the truck comes to a stop, and seamlessly restarts when the accelerator is pressed, reducing idling time by a substantial 60%.
The Auto Start/Stop feature is a game-changer for truck operators, not only saving money on fuel but also reducing engine wear and tear. This is achieved by minimising the amount of time the engine idles while the truck is stationary, such as during loading and unloading operations or when stopped in traffic.
The system is designed with intelligence, as demonstrated by its ability to monitor the battery levels and automatically turn on the engine to initiate charging when the batteries reach a critical level. This proactive approach ensures the truck's batteries are always ready to power auxiliary functions, such as climate control, and it eliminates the risk of a drained battery preventing the truck from starting.
In addition to the economic and maintenance benefits, the Auto Start/Stop feature also contributes to a more sustainable approach to trucking. By reducing idling time, fuel consumption and emissions are lowered, leading to a greener impact on the environment. This not only benefits the planet but also enhances the public perception of the trucking industry.
While the Auto Start/Stop feature is generally well-received, some users have encountered instances where it did not function as expected. Common issues include a low battery, wiring problems, and faulty sensors, which can usually be resolved by a qualified mechanic. Kenworth T680 owners can also refer to online resources and communities for troubleshooting advice and to share their experiences with this cutting-edge technology.

The auto start feature may not work due to faulty sensors
The auto start feature on your Kenworth T680 is designed to save fuel and reduce engine wear and tear by automatically shutting down the engine when the truck comes to a stop and restarting it when the accelerator is depressed. However, several owners have reported issues with the auto start feature not working properly.
One of the most common reasons for the auto start feature failing to work is a low battery. If your battery is low, it won't have sufficient power to operate the auto start. In this case, you will need to charge or replace the battery to get the auto start working again.
Another potential cause of auto start malfunction is faulty wiring. If you suspect this to be the issue, it is recommended to consult a mechanic, who can diagnose and address any wiring problems.
Additionally, the auto start feature may not work due to faulty sensors. In this case, you will need to take your truck to a mechanic for diagnosis and repair of the faulty sensors.
There are also a few other reported issues with the auto start feature. Some owners have mentioned that the auto start rarely works, requiring them to manually reset it. Others have reported issues with the auto start test running noisily and waking them up, or the auto start not engaging at all.
If you are experiencing issues with the auto start feature on your Kenworth T680, it is recommended to consult a mechanic or a KW dealer for further diagnosis and repair.

The idle shutdown feature can be overridden
The Kenworth T680's idle shutdown feature is designed to save fuel and reduce emissions by automatically shutting down the engine when the truck is idle. While this feature is beneficial for the environment and your fuel bill, it can be frustrating if you need to keep your engine running, such as when waiting in line.
One way to override the idle shutdown is to use the "Idle Shutdown Override" button on your dashboard. To activate this feature, simply press and hold the button for about five seconds. The button is typically located to the left of the steering wheel, near the bottom of the center stack. Once activated, your truck will remain running indefinitely while idling. Remember to deactivate the override when you are finished so that your truck does not accidentally stay on.
Another method to bypass the idle shutdown feature involves locating the fuse box, typically found under the hood near the battery. You can then remove the "Idle Shutdown" fuse using a pair of pliers or a screwdriver. This will disable the idle shutdown feature, but it is important to note that this method may require some technical knowledge and expertise.
Additionally, some sources suggest that you can override the idle shutdown by releasing the brakes and chocking the wheels. If this does not work, you may need to modify the programming in the engine ECM.
It is worth noting that, due to emissions laws, it may not be possible to disable the idle shutdown feature until the engine has reached a certain number of miles and/or hours. In such cases, you may need to contact your dealer to request that the idle shutdown be disabled.
While the idle shutdown feature can be overridden, it is important to use this ability sparingly and only when necessary. The feature is designed to reduce fuel consumption and emissions, so overriding it will have the opposite effect on the environment and your fuel costs.
