Switch the charging and control circuits cleanly with the Standard Ignition Battery Charge Relay / Multi-Function Relay (RY1948). A relay uses a low-current control signal to open and close a separate higher-current circuit, letting the vehicle's electronics energize the load without routing full current through the control side. It installs as a direct-fit replacement for the 2017-2018 Hyundai Ioniq [All] and the 2017-2018 Hyundai Sonata [All], with the listed applications using one relay.

  • Composite housing: built to hold up against heat and the demanding conditions of an under-hood environment.
  • Certified production: manufactured at TS16949- and ISO9001-certified facilities.
  • OE experience: produced by a global manufacturer of original-equipment ignition products, with quality control maintained from componentry through the finished part.
  • Connections: 12-volt relay with four male pin terminals in a rectangular connector.

Mounting bracket is not included. Country of origin: Japan. If a failed relay is the cause of a charging-circuit fault, RY1948 replaces it to switch the circuit again — diagnose the circuit first, since the same symptoms can have other causes.

Interchange: Manufacturer part number RY1948.

Frequently Asked Questions

What does the RY1948 relay do?

It uses a low-current control signal to open and close a separate higher-current circuit, so the vehicle's electronics can switch the load without carrying full current through the control side.

Which vehicles does this relay fit?

It is a direct-fit replacement for the 2017-2018 Hyundai Ioniq [All] and 2017-2018 Hyundai Sonata [All]. See the Buyer's Guide tab to confirm your vehicle.

Is a mounting bracket included?

No. The mounting bracket is not included with this relay.

What are its electrical specs and connector?

It is a 12-volt relay with four male pin terminals in a rectangular connector.

What are signs this relay may need replacing?

Intermittent or dead operation of the circuit it controls can be a sign. Diagnose the circuit first, as the same symptoms may have other causes; if the relay is at fault, RY1948 replaces it.
