Jeep Grand Cherokee has Electronic Power Steering (EPS), which is a type of power steering system that uses an electric motor to assist the driver in steering the vehicle. Unlike traditional hydraulic power steering systems, which rely on a pump and fluid to provide assist, EPS systems use an electric motor to provide the assist.
The system is controlled by an electronic control module (ECM) which receives inputs from various sensors such as the steering angle sensor, vehicle speed sensor, and torque sensor. The ECM uses this information to control the electric motor and provide the appropriate amount of assist to the steering mechanism.
EPS systems offer several advantages over traditional hydraulic systems such as better fuel efficiency, improved steering feel, and greater flexibility in terms of vehicle design. EPS systems can also be integrated with advanced driver assistance systems, such as lane departure warning, to provide a more comfortable and safe driving experience.
Electric Power Steering (EPS) Fault Warning Light
The EPS system is controlled by an electronic control module (ECM) that monitors the system for any faults or malfunctions.
If the EPS Fault Warning Light illuminates, it indicates that a problem has been detected in the EPS system. The light will remain on until the problem is fixed. Common causes of the EPS warning light coming on include a fault with the steering angle sensor, a problem with the EPS control module, or a failure of the EPS motor.
If the EPS warning light comes on, it is important to have the vehicle checked by a professional as soon as possible. This is because a problem with the EPS system can affect the vehicle’s handling and steering, which can increase the risk of an accident. In some cases, the EPS system may stop working altogether, which can make it difficult or impossible to steer the vehicle. Therefore, it is important to address the problem as soon as possible.
