SDS Error: Refer To 3x02228 I/O C.

This document provides troubleshooting steps for an SDS Error, which occurs when an unreasonable SDS input signal is detected while a car is stopped or running. The steps include: 1) Checking the P48V power, 2) Checking circuit wiring and connector contact status, 3) Checking the input buffer status by applying DC48V power and monitoring signal changes, and 4) Checking SDS operation by inputting signals to SD1-6U(D) individually. If no signal differences are detected, the input buffer may have failed and the PCB would need replacing.
