The automotive relay apparatus is used to control a high electric current, such as electric cooling fan, or a / c compressor clutch having a low-Circuit Tester ADD210 switch or computer circuitry. This makes use of the lightweight cabling and switch, as well as computer control possible in today's cars and light trucks. It can be seen, this additional weight saver option in improving the fuel mileage.
1
Find the relay, refer to your service manuals. If you do not have a specific service manuals for your vehicle, you can get an web format. Get out of this. Specialty shops, it includes the same information, it is low cost, online subscription format.
2
disconnect the relay, open the ignition switch to the run BENZ W164 CAN FILTER. Then, the test relay power and grounding type plug. Looking in the back of the relay, you will notice that two runs to plug four wire diameter is greater than the other two. These are in the the high current circuit interconnection. Everyone should are vested with authority when the key is that there should be terrestrial and the others are. If no power supply, check the fuse, if there is no reason to check device the relay control.
3
Test residual two power and ground lines. A conductor to be grounded, and, if the circuit is a computer controlled, only the ground with the key. Will carry the rest of the line, if it is a computer-controlled, in the ON position, the most ADD210. If there is no ground to ensure that the computer on the ground conditions have been met. These conditions can be in your service manuals. If the conditions are met, there is no existence of a ground, the computer fails.
If there is no power supply power cord, check the fuse and switch.
