Wire and terminal fault can also be due to the wiring harness and body (
Or in the switch between internal short circuit.
Inspection shall, first of all, whether in the body of the terminals fixed before, then you can follow the steps below for testing.
1, check the wiring on off first remove the control computer terminals, on either side of the ECU and the sensors to measure the terminal corresponding to the resistance between terminals.
As ohm resistance is not greater than 1, then wire is normal, for the next examination.
When measuring wire resistance, it is best in vertical and horizontal directions and gently shake wire in order to improve the accuracy of the measurement, at the same time pay attention to, for the majority of wire terminals, multimeter table rods from the connector backend inserted, but for the waterproof model with waterproof set of terminals table rods can't insert from the back end, because the insert a bit not careful will deform the terminal.
2, short circuit resistance checks on either side of the first remove the ECU control computer and sensor wire terminals, and measurement on both sides of the connector terminals between row and body resistance.
Measurement, the table take the iron rod end body, on the other side to measure on the wire connector on both sides respectively, if the resistance is greater than 1 ohm and body without fault show that the wire.
3, terminal and contact pressure appearance inspection should first remove the terminals, one by one check touch connector terminals on the presence of rust and dirt, and the corrosion and dirt should be clean.
Then check that the terminal is loose or damaged, whether terminals fixed, when gently pull the terminal should be no loose phenomenon.
Where is on the other hand, if a city in a hole plug terminal comes out easier than other seat holes, then the seat hole in use may cause poor contact failure.
