The following 5 types of cable beam failure:

① Break circuit; ② Short circuit; ③ Wrong path; ④ virtual connection; ⑤ not connected.

There are mainly the following 8 types of plug -in faults:

① error needle; ② pouring needle; ③ virtual connection; ④ short connection; ⑤ retreat; ⑥ failure; ⑦ not inserted; ⑧ damaged.

In order to quickly solve the abnormal work of electrical appliances that appear on the entire vehicle, you must have information such as the principles of vehicle electrical, the two -dimensional wire beam chart, and the control strategy of the vehicle electrical appliances, and be proficient in the above information.

Essential tools used: universal meter, plug -in pushes, pins, PVC insulating tapes, pointed clamps, tip piping clamps, etc. The general problems are as follows.

(1) The problem of wire beam plug -in parts

If there is a problem with the connection of the electrical line beam, you can check according to the following steps:

1) Check whether the car electrical plug -in and wiring beam interpretation is connected in place.

2) Check whether the cable beam is connected with firm connection, whether the pins appear to be withdrawing, and bending.

3) According to the definition of the cable drawing, check whether the connecting line beam position is correct.

(2) Power supply power supply problem

1) Use a multimeter to detect whether the power supply supply is normal, and pay special attention to whether the power supply value is within the normal working range of using electrical appliances.

2) Check whether the melting corresponding to the appliances is fused and replaced.

3) Check whether the wire protective layer is damaged and leakage.

(3) Main iron problem

1) Check whether the electric wire beam is firmly ironed with the body.

2) Check whether the iron point is in contact with the body and connect well.

3) Use a multimeter to check whether the iron beam is well connected with the body.

(4) Make power power problems

1) Some electrical appliances not only have power supply, but also have the power supply (ACC power, IG power), and confirm that enable power and gears correspond to.

2) Check whether the use of electrical plug -in and wiring beam interpolations is inserted, and check whether the insertion is in place.

3) Check whether the cable beam is firmly connected to the pin, whether the pins appear to be withdrawing, and bending abnormal phenomena.

4) Define the position of the connecting line beam in accordance with the line drawing drawing.

5) Use a multimeter to conduct relevant lines for turning testing.
