Troubleshooting steps故障诊断步骤

①Power on check上电检查

1. Repower the vehicle, use the diagnostic tool to read and clear the fault codes, and check whether the fault codes and symptoms are eliminated.车辆重新上电，使用诊断仪读取并清除故障码，检查故障码及症状是否排除。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Go to step 2.去步骤2。

②Replace the electric power steering column更换电动助力转向管柱

1. Replace the electric power steering column with a new one and check whether the fault code and symptoms are eliminated.更换新的电动助力转向管柱，检查故障码及症状是否排除。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Look for causes from other symptoms.从其他症状查找原因。   Caution:注意： ♦  After replacing the electric power steering column, you need to use a diagnostic instrument to recalibrate the electric power steering column.更换电动助力转向管柱后，需用诊断仪对电动助力转向管柱重新标定。
