2.2 有故障代码时的故障检测诊断2.2.1 故障代码C0278/11、C0279/12——ABS感应电磁阀继电器电路故障的检测诊断每个ABS感应电磁阀都是由ABS感应电磁阀继电器供电的,点火开关打开以后,若初始化检查成功,则ABS感应电磁阀继电器闭合;当所有ABS感应电磁阀供电电压低于2.5V时,ABS感应电磁阀继电器断开;ABS感应电磁阀供电电压大于6V时,ABS感应电磁阀继电器闭合。ABS感应电磁阀继电器电路的检查步骤(特别提醒:使用手持式测试仪进行故障检测诊断
2.2 Fault Detection and Diagnosis with Fault Codes 2.2.1 Fault Codes C0278 / 11, C0279 / 12 - Detection and Diagnosis of Faults in the Circuit of ABS Sensor Solenoid Relay Each ABS sensor solenoid valve is powered by ABS induction solenoid valve relay, When the ignition switch is turned on, if the initialization check is successful, the ABS induction solenoid valve relay is closed; when all the ABS induction solenoid valve supply voltage is lower than 2.5V, the ABS induction solenoid valve relay is off; ABS induction solenoid valve supply voltage is greater than 6V, ABS induction solenoid valve closed. ABS induction solenoid valve relay circuit inspection steps (Special Reminder: The use of hand-held tester fault detection and diagnosis
