Some of the electrical accessories in the vehicle which employ relays include the fuel injection system, horns, starter, and fog lamps, whereby a low amperage control circuit will switch on a high amperage power circuit. In the case that there is a defective relay, there is no power supplied to the components and defective relays cannot be repaired and has to be replaced. There are three basic types of relays: for the normally-open type; Type A and Type B, while for the five-terminal type. Both Type A and Type B have same internal wiring but different external terminals, while five terminal relays have different internal wiring as well as an extra terminal. To test a relay, the relay should be taken out of the car and then, via an ohmmeter, one should check the continuity. Normally-open type A relays are applied to air conditioning relay, headlight relay and so on, their type can be distinguished by terminals. Others regarded testing as the process of checking whether or not there is continuity between particular terminals when they are active and when they are inactive. As for Type B relay, most of them are normally-open, they include blower motor and rear window defogger, and the identification focuses on terminals. Five terminal relays, used for functions such as moonroof, contain an apparent extra terminal to indicate that they are of this type and testing involves measuring continuity between stated terminals in specific situations.

These cars have a number of electrical add-ons, such as fuel injection system, horns, starter and fog lamps, which are controlled by relays that ensure transmission of electric signals to the respective components. By allowing low-current control circuit to open and close high-current power circuit relays function. These relays can be found in the engine compartment fuse/relay box and near the fuse and relay boxes under the dashboard. There are usually three main types: normally-open type-A , normally-open type-B, and five-terminal type ones. The internal circuitry is similar on Type A and Type B relays while they differ in external spade terminal arrangement and numbering. Compared to Type A or Type B relays, five-terminal relays have different internal circuitry plus an added external spade terminal. To test a relay it must be removed from the vehicle and an ohmmeter used to check for continuity. Normally open Type A relays for instance which are used for various purposes such as air conditioning; horns; window lifters have four external spade terminals arranged in two rows. When you unplug them from power sources you should make sure there is no connection between terminals No1 &No2 on one hand but also that there is between terminal No 3 connected to power source via (terminal No 4) a ground wire respectively.The normally-open Type B ones similarly have four external parallel rows of spade terminals just like their counterparts above mentioned for example blower motors; rear defoggers . For these B-type testing is simple which requires breaking connection between contact points No1&No3 when current ceases to flow through them whereas creating path between contacts No1&No3 using their corresponding feeds wires from connectors No2&No4 which are connected with interfaced power line as well as grounded with earth respectively.A last category we will take care about here is five-terminal devices known for moonroof control ; high beam cut-off and others need us to examine continuity between point No 1 &No 4 without power supply whereas later on it should be established by joining terminal No. 3 to power and the ground respectively provided that connection has been completed at points No2&No5. These relay switches are normally discarded as they cannot be repaired.

A defective relay will prevent the circuit it controls from operating correctly.

Yes that is the VSA/ABS relay.
