5.案例5 故障现象:Cayenne S E-hybrid,混合动力报警(如图42所示),在高压电源电子设备里有故障码:P0A2B00 Drive Motor “A” Temperature Sensor Circuit Range/Performance;P0A2D00 Drive Motor “A” Temperature Sensor Circuit High。故障诊断:因最近有相似案例,首先检查适用于高压电源电子设备的低温冷却系统回路,t对换电源电子设备的节温器,故障依旧。检查适用于电机的高温冷却系统回路、冷却液
5. Case 5 Symptom: Cayenne S E-hybrid, hybrid alarm (as shown in Figure 42), fault code in high-voltage power electronics: P0A2B00 Drive Motor “A” Temperature Sensor Circuit Range / Performance; P0A2D00 Drive Motor “A ” Temperature Sensor Circuit High. Troubleshooting: Because of recent similar cases, first check the circuit for low-temperature cooling system for high-voltage power electronics, power switch thermostat temperature, the fault still. Check for high temperature cooling circuit, coolant for motor
