    欧宝汽车故障案例详解
    2021-11-9 19:38:27

    1.高压电池采样线故障故障现象欧宝车辆SOC78%,无EV模式。如下图所示,仪表报“请检查动力系统”,BMS存在故障码:P1A3D00(负极接触器回检故障)。

    High voltage battery sampling line fault phenomenon Opel vehicle soc78%, no EV mode. As shown in the figure below, the instrument reports "please check the power system", and there is a fault code p1a3d00 in BMS (negative contactor recheck fault).

    仪表显示“请检查动力系统”

    The instrument displays "please check the power system"

    系统存在故障码内容检修过程① 因车辆提示动力系统故障,且BMS存在故障码P1A3D00。首先对BMS负极接触器电源、控制电路进行检查。

    There are fault code contents in the system. Maintenance process ① the vehicle indicates power system fault, and the BMS has fault code p1a3d00. Firstly, check the power supply and control circuit of BMS negative contactor.

    ② 检查BMS负极接触器F脚电源供给正常(k161母端)。

    ② Check that the power supply of F pin of BMS negative contactor is normal (k161 female terminal).

    ③ 进一步排查发现高压电池采样端子(k161公端——公端可理解为插头端子,母端为插座端子,下同)F脚出现退针现象。

    ③ Through further investigation, it was found that the pin F of the sampling terminal of the high-voltage battery (k161 male terminal - the male terminal can be understood as the plug terminal, and the female terminal is the socket terminal, the same below) had a needle withdrawal phenomenon.

    连接端子退针故障排除更换高压电池采样端子,如无单独部件更换,则须更换高压电池包总成。

    Remove the needle withdrawal fault of the connecting terminal and replace the sampling terminal of the high-voltage battery. If there is no separate component replacement, replace the high-voltage battery pack assembly.

    2.电池管理系统初始化失败故障现象欧宝汽车无法启动,系统故障灯点亮,上位机上报故障为电池管理系统初始化失败(P3013)。

    The initialization of battery management system fails. The fault phenomenon is that Opel cannot start, the system fault light is on, and the upper computer reports the fault as the initialization failure of battery management system (p3013).

    故障分析① LBC板供电线路故障。

    Fault analysis ① LBC board power supply line fault.

    ② LBC板故障,LBC板实体如下图。

    ② The LBC board is faulty, and the LBC board entity is shown in the figure below.

    故障排除断开高压电池低压端接插件,车辆上ON挡电,检测LBC板12V供电是否正常。如供电正常,则为LBC板故障;如供电异常,则需结合维修手册排查供电线路。

    Troubleshooting: disconnect the low-voltage terminal connector of high-voltage battery, turn on the vehicle, and check whether the 12V power supply of LBC board is normal. If the power supply is normal, it is LBC board fault; If the power supply is abnormal, check the power supply line in combination with the maintenance manual.
