C101038	Wheel speed sensor failure - wrong direction轮速传感器故障--方向错误	1. When there is a difference in wheel speed direction, but a specific wheel speed sensor cannot be located, this fault will be reported.1.当产生轮速方向差异，但是无法定位具体某一个轮速传感器时，则会报出此故障

Troubleshooting steps故障诊断步骤

①Power on check上电检查

1. Power on the vehicle again and check whether the fault code and symptoms are eliminated.车辆重新上电，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。

②Check the installation of the in-line wheel speed sensor检查直插式轮速传感器的安装

1. Check whether the in-line wheel speed sensor is installed correctly.检查直插式轮速传感器安装是否正确。 Are the test results normal?检查结果是否正常？ Yes是 Go to step 3.去步骤3。 No否 Reinstall the in-line wheel speed sensor.重新安装直插式轮速传感器。

③Replacing the in-line wheel speed sensor更换直插式轮速传感器

1. Replace with a new in-line wheel speed sensor and check whether the fault code and symptoms are eliminated.更换新的直插式轮速传感器，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 4.去步骤4。

④Replacing the integrated brake control unit更换集成式制动控制单元

1. Replace with a new integrated brake control unit and check whether the fault code and symptoms are eliminated.更换新的集成式制动控制单元，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 integrated brake control unit, you need to use a diagnostic tool to recalibrate the integrated brake control unit.更换集成式制动控制单元后，需用诊断仪对集成式制动控制单元重新标定。 ♦  After replacing the integrated brake control unit, the brake line bleeding operation is required.更换集成式制动控制单元后，需进行制动管路排气操作。
