Keep the charging circuit switching cleanly with the Standard Ignition Load Leveler Relay / Battery Charge Relay RY2003. This relay is a direct-fit replacement for the 2011-2015 Hyundai Sonata and 2011-2015 Kia Optima — see the Buyer's Guide tab for engine-level fitment. As an electromechanical switch, it uses a low-current signal to open and close a higher-current circuit, controlling power to the load it serves; if a failed relay is the cause of intermittent or lost operation in that circuit, this replaces it.

  • Built to last: a high-quality composite housing helps protect against harsh temperatures and demanding under-hood conditions for lasting reliability.
  • Certified quality: manufactured at TS16949 and ISO9001 certified facilities to meet high industry standards.
  • Enhanced wear resistance: brass or copper contacts where specified provide extended wear resistance, even in high-stress applications.
  • Renowned global manufacturer: made by a global manufacturer of original-equipment ignition products, with quality control maintained from componentry to finished product.

Signs a relay may need replacing include an intermittent, no-longer-switching, or dead circuit that the relay controls. Diagnose the cause before replacing.

Frequently Asked Questions

What vehicles does the RY2003 relay fit?

It is a direct-fit replacement for the 2011-2015 Hyundai Sonata and 2011-2015 Kia Optima. Check the Buyer's Guide tab to confirm engine-level fitment for your vehicle.

What does this relay do?

It is an electromechanical switch that uses a low-current signal to open and close a higher-current circuit, controlling power to the load it serves.

Is this the same as a battery charge relay?

Yes. It is listed under both names — Standard Ignition Load Leveler Relay and Battery Charge Relay — for the same part, MPN RY2003.

What are signs this relay may need replacing?

Intermittent operation, a circuit that no longer switches, or a dead circuit the relay controls can be signs. Diagnose the cause before replacing, as other components can produce similar symptoms.

What interchange numbers does it cross to?

It replaces R7506, RLYB10237, AR7506, 375144R000, and 5144R000. Match one of these numbers to confirm you have the correct relay.
