Switch high-current circuits cleanly with the Standard Ignition Relay RY-598 — an electromechanical relay that uses a low-current control signal to open and close a higher-current circuit on demand. It drops in as a direct-fit replacement for the 2016 Audi TT, 2001-2006 Hyundai Santa Fe, 1999-2005 Hyundai Sonata, 2001-2003 Kia Magentis, and 2001-2003 Kia Optima.
Because this relay is cataloged under several categories, it can serve any of those switching roles depending on how it is wired into your vehicle's circuit:
- Multi-role relay: listed as an ABS Relay, Accessory Power Relay, Fuel Injection Relay, Ignition Relay, and Main Relay — the part is known by all of these names.
- Control function: a small control-side signal energizes the relay to power the load-side circuit, so the switching current stays off delicate control components.
- Direct-fit replacement: designed to install for the listed applications.
Relays can fail open, stick closed, or switch intermittently. If a faulty relay in one of these circuits is the cause of an intermittent no-start, dropped accessory power, or a circuit that won't energize, this replaces it. Diagnose the circuit before replacing.
