The B1873 trouble code signals a malfunction from the turn signal and hazard light power feed circuit.
B1873代码是一种通用的OBD-II故障代码，可检测转弯信号和危险电源进液电路误差，该误差控制前后信号灯，这也是危险警告灯。如果车身控制模块或动力总成控制模块（PCM）检测到转向信号和危害功率进给电路的异常电压读数，则可以触发B1873代码。
Some causes of the B1873 trouble code are:
When the B1873 code is stored, the turn signals and hazard warning lights likely won’t work.
The B1873 code should be diagnosed with the help of a standard OBD-II trouble code scanner. A trained mechanic will use the scanner to view the freeze frame data and gather information about the code, as well as to check for the presence of additional trouble codes. If there are multiple codes present, then they will need to be diagnosed in the order that they appear in. The mechanic will then need to reset the trouble codes, restart the vehicle, and check for the presence of the B1873 code. If the code is no longer present, it was likely the result of an intermittent issue, or an erroneous trigger.
If the code remains detected, the mechanic will begin by testing the turn signal lights. If only some of them are failing to operate, then a blown bulb is the likely culprit. Next, the technician will visually inspect all of the electrical components in the turn signal system, and replace any damaged fuses, wires, and connectors. The voltage in the circuit will then need to be checked. If the problem persists, then the turn signal switch and flasher relay will require inspection.
机械师替换或维修任何组件后，应重置故障代码，重新启动车辆以及B1873代码再次检查。这有助于技术人员在解决问题后立即知道。
诊断此代码时，最常见的错误是由于未能遵守OBD-II诊断方案。该协议应始终一步一步地粘在依据，因为这有助于增加进行彻底检查的机会，并减少维修不当的机会。
由于系统中的电气组件从未检查过，因此通常会不必要地更换转向信号开关和闪光灯继电器。
具有检测到B1873故障代码的车辆可能会有无法使用的转弯信号和危险警告灯。这两者都是任何车辆中重要的安全功能，并且无法使用适当的转弯信号会导致固定票。出于安全性和实用性，应尽快检查任何经历B1873故障代码的车辆。
Repairs for the B1873 code include:
该代码是制造商特定的代码，这意味着该定义因汽车制造商而异。B1873代码在某些汽车中指出了转弯信号和危害功率进料电路问题，但在其他车辆中代表了完全不同的诊断错误。对于机械师而言，始终要在诊断和检查B1873代码时始终了解正在使用的车辆。
