The Ingenuity of Failsafe Engine Mode in Your Jaguar

by Dutch Silverstein November 21, 2021

As the owner of a Jaguar, you’re driving one of Europe’s most coveted luxury brands. A Jaguar is an investment, and to help you protect you and your vehicle, Jaguar offers a failsafe engine mode. As technology has evolved over time, this brilliant feature was created to help protect your vehicle from serious damage, and helps prevent accidents for the driver and their passengers.

This design has led to a decrease in accidents and fatalities, proving the failsafe engine mode to be a ground-breaking safety feature on newer vehicles. Let’s discuss the purpose of failsafe engine mode, what causes failsafe engine mode to trigger, what happens when failsafe engine mode is activated, and where to go for help when your vehicle’s failsafe engine mode is activated.

The Purpose of Failsafe Engine Mode

In the event something stops working properly in your Jaguar, failsafe mode is an automatic feature that helps prevent the damaging effects from causing more harm which can be costly to repair. Failsafe mode also helps prevent the chance of an accident, as it will limit how fast you can drive your vehicle, making it an outstanding safety feature on newer vehicles.

Unfortunately, sometimes the failsafe engine light illuminates in error when there isn’t a real problem, sending a false alarm to the driver. This is why it is important to have a trusted Jaguar specialist to diagnose the problem and reset the false-warning light if it is necessary.

What causes failsafe engine mode to trigger?

Failsafe engine mode is there to kick in when it detects something is wrong with your vehicle. But when the failsafe engine mode light illuminates on your dashboard, it could be due to any number of problems, which can be frustrating to try to figure out. Here are some of the common reasons failsafe engine mode is triggered:

  • Transmission System: The transmission system is responsible for controlling the speed and direction in which the car is driven, and oftentimes the failsafe engine mode is triggered by problems with it.
  • Sensors: Your engine’s sensors, such as the mass airflow sensor and O2 sensor, can easily trigger failsafe engine mode in your vehicle. A failing sensor is a small but significant component of your vehicle’s engine that controls the air-to-fuel ratio necessary for your vehicle to run at optimal performance. If any of your engine’s sensors are dirty or failing, the failsafe engine mode will activate.
  • Electrical System: A fault in the electrical system can also trigger failsafe engine mode into gear. Failsafe engine mode is programmed to work based on your vehicle’s computer, and since electrical system problems cause a disruption with the car’s computer, it can trigger the failsafe engine mode into action.

What happens when failsafe engine mode is activated?

Now that you know the types of issues that cause failsafe engine mode to activate, let’s discuss what happens when it is activated.

Your cruise control will no longer work due to the transmission system becoming locked by the failsafe. If you are driving your vehicle in a slower gear, it will become impossible to change gears and speed up since your car detects it is unsafe to do so. This is to protect the engine from further damage at higher rpms. The slower the engine is turning, the less damage that can be done. It will allow you to “limp” to a safe area such as a rest stop, home, or service center, but it will not allow you to drive the way you consider to be normal.
