U1702 Jeep Code - Electric Power Steering Signal Invalid

The diagnostic code U1702 indicates an issue with the Electric Power Steering (EPS) system, specifically signaling that the EPS module has detected an invalid signal. The EPS system is designed to enhance steering performance by using an electric motor to provide assistance, rather than relying on traditional hydraulic systems. This electric system utilizes various inputs such as steering torque, steering angle, vehicle speed, and engine speed, which are communicated through the Controller Area Network (CAN). When functioning correctly, the EPS system adjusts the level of steering assistance based on driving conditions, making it easier to steer at low speeds and providing more resistance at higher speeds for better control. If the EPS module detects an invalid signal, it may lead to a loss of power steering assistance, making the vehicle harder to steer, particularly at low speeds. Ignoring this code can result in long-term damage to the EPS system, increased wear on steering components, and potentially unsafe driving conditions due to reduced steering responsiveness. Additionally, the EPS system is integrated with the vehicle's stability control, meaning that issues with the EPS can also affect the overall stability and handling of the vehicle. If not addressed promptly, drivers may experience increased fatigue and difficulty maneuvering the vehicle, especially in tight spaces or during parking.
