汽車(chē)發(fā)動(dòng)機(jī)線束的更換要遵循怎樣的標(biāo)準(zhǔn)?

對(duì)于汽車(chē)發(fā)動(dòng)機(jī)線束老化、嚴(yán)重破損、內(nèi)部導(dǎo)線短路或內(nèi)部導(dǎo)線短路斷路的故障,通常須更換線束。那么汽車(chē)發(fā)動(dòng)機(jī)線束的更換要遵循怎樣的標(biāo)準(zhǔn)?下面濟(jì)南沃爾沃汽車(chē)養(yǎng)護(hù)人員為你講解:
For the faults of aging, serious damage, internal wire short circuit or internal wire short circuit and open circuit of automobile engine wiring harness, it is usually necessary to replace the wiring harness. What standards should be followed for the replacement of automobile engine harness? The maintenance personnel of Jinan Volvo Cars will explain to you:
1.更換線束前的線束質(zhì)量檢查。
1. Check the harness quality before replacing the harness.
為確保線束安全可靠,使用前須嚴(yán)格把控,應(yīng)認(rèn)證檢查,發(fā)現(xiàn)缺陷不得使用,防止不合格產(chǎn)品帶來(lái)的危害。有條件,好使用儀器來(lái)檢查。
In order to ensure the safety and reliability of the harness, the harness must be strictly controlled before use, and it should be certified and inspected. Defects found should not be used to prevent the harm caused by unqualified products. If conditions permit, it is easy to use instruments to check.
檢查內(nèi)讓包括:線束有無(wú)破損,插接器有無(wú)變形,端子有無(wú)銹蝕,插接器本身、線束與插接器有無(wú)接觸不良,以及線束有無(wú)短路、短路的情況。線束的檢驗(yàn)是不可少的。
The inspection includes: whether the harness is damaged, whether the connector is deformed, whether the terminal is rusted, whether the connector itself, harness and connector are in poor contact, and whether the harness is in short circuit or short circuit. The inspection of harness is indispensable.
2.排除車(chē)上所有的電氣設(shè)備的故障,方可更換線束。
2. Remove the faults of all electrical equipment on the vehicle before replacing the harness.

3.線束更換步驟。
3. Harness replacement steps.
(1)準(zhǔn)備線束拆裝工具。
(1) Prepare the harness disassembly tool.
(2)拆卸故障車(chē)輛的蓄電池。
(2) Remove the battery of the faulty vehicle.
(3)斷開(kāi)與線束相連的用電設(shè)備的插接器。
(3) Disconnect the connector of the consumer connected to the harness.
(4)全程做好工作記錄。
(4) Keep work records throughout the process.
(5)松開(kāi)線束固定。
(5) Loosen the harness fixing.
(6)取下舊線束,裝配新線束。
(6) Remove the old harness and assemble the new harness.
4.檢驗(yàn)新線束連接的正確性。電線束插接器與電氣設(shè)備的連接是否正確是先要確認(rèn)的,還要確保蓄電池的正負(fù)連接無(wú)誤。
4. Check the correctness of the new harness connection. The correct connection between the wire harness connector and the electrical equipment should be confirmed first, and the positive and negative connections of the battery should also be ensured.
檢查時(shí),可以展示不接蓄電池的搭鐵線,改用燈泡(12V,20W)做試燈。在此之前,車(chē)上其它的用電設(shè)備要關(guān)閉,然后在蓄電池負(fù)與車(chē)架搭鐵之間用試燈串連接。電路一旦有問(wèn)題出現(xiàn),試燈就開(kāi)始變亮。
During the inspection, the grounding wire without battery can be displayed, and the light bulb (12V, 20W) can be used as the test lamp. Before that, turn off other electrical equipment on the vehicle, and then connect the battery negative and frame ground with a test lamp string. Once there is a problem with the circuit, the test lamp will start to light up.
當(dāng)電路的故障排除之后,把燈泡取下來(lái),用一只容量為30A的保險(xiǎn)絲串接在蓄電池負(fù)與車(chē)架搭鐵端之間。這時(shí)的發(fā)動(dòng)機(jī)不要啟動(dòng),對(duì)車(chē)上相應(yīng)的電源設(shè)備一個(gè)個(gè)進(jìn)行接通,并且要對(duì)相關(guān)的線路逐一的全面檢查。
After the circuit fault is eliminated, take down the bulb and connect it in series with a 30A fuse between the negative side of the battery and the frame ground terminal. Do not start the engine at this time. Connect the corresponding power equipment on the vehicle one by one, and check the relevant lines one by one.
5.通電工作檢驗(yàn)。電氣設(shè)備以及相關(guān)的線路如果確認(rèn)沒(méi)有問(wèn)題,就可以取下保險(xiǎn)絲,連接好蓄電池搭鐵線,進(jìn)行通電檢驗(yàn)。
5. Power-on work inspection. If there is no problem with the electrical equipment and related wiring, you can remove the fuse, connect the battery ground wire and conduct power-on inspection.
6.檢查線束的安裝。好,應(yīng)檢查線束安裝,確保線束安裝正確并牢固。
6. Check the installation of harness. OK, check the harness installation to ensure that the harness is installed correctly and firmly.
在線束修復(fù)及更換的工作中,應(yīng)加強(qiáng)研究,不斷完善維修規(guī)范,確保汽車(chē)運(yùn)用與維修的安全性和可靠性。更多相關(guān)事項(xiàng)就來(lái)我們網(wǎng)站http://www.langqie.cn咨詢了解吧!
In the work of harness repair and replacement, research should be strengthened, and maintenance specifications should be constantly improved to ensure the safety and reliability of vehicle operation and maintenance. Come to our website for more relevant matters http://www.langqie.cn Ask about it!
