故障現(xiàn)象;有一臺2013年生產(chǎn)的480D沃爾沃車主反映，停車后再啟動顯示屏出現(xiàn)GPS故障。無論怎么啟動發(fā)動機就是沒有著火的現(xiàn)象，這是一臺2013年生產(chǎn)的沃爾沃，這種年齡的沃爾沃已經(jīng)不存在欠費現(xiàn)象，為了安全起見和售后的朋友溝通了一下，讓朋友在后臺檢查一下這臺車輛是否有拖欠費用的情況，溝通確認后無欠費開始維修。

　　Fault phenomenon; A car owner of a 480D Volvo produced in 2013 reported GPS malfunction on the display screen after parking and restarting. No matter how the engine is started, there is no fire phenomenon. This is a Volvo produced in 2013. At this age, Volvo no longer has any outstanding fees. For safety reasons, I communicated with my after-sales friends and asked them to check in the background whether there are any outstanding fees for this vehicle. After confirming that there are no outstanding fees, we will start repairing it.

　　遇見GPS的情況一定要確認在不沒有欠費的情況下才可以維修，否則后患無窮。到現(xiàn)場后根據(jù)顯示屏提示的故障進行維修檢查GPS相關(guān)的線路后，發(fā)現(xiàn)GPS電源缺失，一個蓄電池電源，也就是咱們說的長電源。

　　When encountering GPS situations, it is necessary to confirm that there are no outstanding fees before repairing, otherwise there will be endless troubles. After arriving at the scene and checking the GPS related circuits according to the displayed faults, it was found that the GPS power supply was missing, a battery power supply, which is what we call a long power supply.

　　這個GPS有兩個電源，第一個是蓄電池電源，另外一個是鑰匙門on電源，檢查相關(guān)線路發(fā)現(xiàn)蓄電池電源的線斷路，接上線之后GPS電源故障障排除，啟動正常過十分鐘之后又出現(xiàn)GPS故障，重新又把GPS相關(guān)的電路重新檢查了一遍，發(fā)現(xiàn)電路是正常的，這說明GPS的內(nèi)部有出問題，讓司機采用應(yīng)急模式工作，把gps拆下后，重新修復(fù)后安裝試車正常。

　　This GPS has two power sources, the first is the battery power source, and the other is the key door on power source. After checking the relevant circuits, it was found that the battery power source wire was broken. After connecting it online, the GPS power supply fault was eliminated. After starting normally for ten minutes, the GPS fault occurred again. After rechecking the GPS related circuits, it was found that the circuits were normal, indicating that there was an internal problem with the GPS. The driver was asked to work in emergency mode, remove the GPS, repair it, and install and test it normally.

　　故障總結(jié)：沃爾沃這款挖掘機，因安裝的GPS生產(chǎn)廠家在質(zhì)量把控方面有缺陷，導(dǎo)致GPS內(nèi)部工作不穩(wěn)定，從而引起了發(fā)動機工作不正常。

　　Fault summary: The Volvo excavator had a quality control defect in the GPS manufacturer installed, which caused unstable internal operation of the GPS and resulted in abnormal engine operation.
