What are the functions and types of relays used in electrical accessories on Acura TL?

Many electrical accessories, such as the fuel injection system, horns, starter, and fog lamps, utilize relays to manage current to components, employing a low-current control circuit to operate a high-current power circuit. A defective relay will prevent the associated component from functioning, and these relays can be found in the engine compartment fuse/relay box and near the under-dash fuse and relay box, with access to the under-dash relays requiring the removal of the left kick panel. There are two primary types of relays: normally-open type A and five-terminal type A. Normally-open type A relays serve various functions, including ABS fail-safe, accessory power socket, air conditioning components, and multiple light relays, characterized by four external spade terminals arranged in a specific configuration. Testing involves checking for continuity between designated terminals with power applied or disconnected. Normally-open type B relays, used for systems like the ABS pump motor and blower motor, also feature four terminals but arranged differently. Five-terminal type A relays, utilized for windshield wiper control, have five terminals in two rows, and testing requires verifying continuity between specific terminals under certain conditions. Five-terminal type B relays, which serve functions such as ACC cut and moonroof controls, follow a similar testing procedure to ensure proper operation.
