Battery sensor is working abnormally电池传感器工作异常

①General inspection一般检查
1. Check whether the battery sensor wiring harness is damaged or broken.检查电池传感器线束是否存在损坏、断裂等现象。 2. Check the battery sensor harness connector for loose connection or damage.检查电池传感器线束接插件是否存在虚接、损坏等现象。 Are the test results normal?检查结果是否正常？ Yes → Go to step 2.是>>去步骤2。 No → Repair or replace the faulty wiring harness or connector.否>>维修或更换故障线束或接插件。
②Check fuse检查保险丝
	1. Check whether the EBS fuse in the battery-positive fuse box is normal.检查正极电器盒中EBS保险丝是否正常。 EBS：7.5A Are the test results normal?检查结果是否正常？ Yes → Go to step 3.是>>去步骤3。 No → Replace the fuse with the same specification.否>>更换相同规格保险丝。
③Check battery sensor power circuit检查电池传感器电源线路
	1. Power status "ON".电源状态“ON”。 2. Use a digital multimeter to measure the voltage between pin 1 of the battery sensor harness connector FB66 and ground.用数字万用表测量电池传感器线束接插件FB66的1号针脚与接地之间的电压。 Standard voltage value: about 14V标准电压值：约14V Are the test results normal?检查结果是否正常？ Yes → Go to step 4.是>>去步骤4。 No → Repair or replace the battery sensor power harness.否>>维修或更换电池传感器电源线束。
④Check the battery sensor LIN communication line检查电池传感器LIN通讯线路
1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。 2. Check whether the battery sensor LIN communication line is normal.检查电池传感器LIN通讯线路是否正常。 Are the test results normal?检查结果是否正常？ Yes → Go to step 5.是>>去步骤5。 No → Repair or replace the battery sensor LIN communication harness.否>>维修或更换电池传感器LIN通讯线束。
⑤Replace battery sensor更换电池传感器
1. Replace the battery sensor and check whether the fault is eliminated.更换电池传感器，检查故障是否排除。 Are the test results normal?检查结果是否正常？ Yes → Fault resolved.是>>故障排除。 No → Find the cause from other fault symptoms.否>>从其他故障现象查找原因。
