Code P1397 Suzuki Description

The P1397 Suzuki diagnostic trouble code (DTC) specifically refers to a rough road signal from the Wheel Speed Sensor (WSSD). The WSSD is a crucial component of the vehicle's Anti-lock Braking System (ABS) and stability control systems. When the vehicle is driving on rough or uneven terrain, the WSSD is responsible for detecting the variations in wheel speed and feeding that information to the vehicle's control modules to adjust braking and stability systems as needed.
