故障现象一辆2006年款卡罗拉1.6 L轿车,发动机故障指示灯、ABS故障指示灯、动力转向故障指示灯等在发动机起动后仍不熄灭,着机后发动机有明显的怠速抖动、加速不顺畅现象。故障诊断与排除接车后,用故障检测仪读取故障代码,结果发现故障检测仪无法进入到发动机电控系统。针对发动机起动后许多故障指示灯同时点亮,故障检测仪无法进入发动机电控系统这一现象,认为是发动机通讯系统故障;

Trouble A 2006 Corolla 1.6 L sedan, engine fault indicator, ABS fault indicator, power steering fault indicator light does not go out after the engine start, the engine after the engine idling jitter obvious acceleration is not smooth phenomenon . Fault diagnosis and troubleshooting After the car, with the fault detector to read the fault code and found that the fault detector can not enter the engine electronic control system. Aiming at the fact that many fault indicator lamps are lit at the same time after the engine is started, the fault detector can not enter the electronic control system of the engine, which is considered to be a fault of the engine communication system.
