ELECTRIC OIL PUMP CONTROLLER INSPECTION AND
REPLACEMENT (RECALL 246)
This TSB supersedes TSB # 23-01-071H-1 to add 2024MY for the Tucson (NX4) & revise the
applicable production dates for the Palisade (LX2) & Tucson.

 IMPORTANT
Vehicle repairs related to safety recalls are critically important and must be performed properly in
accordance with TSB procedures. Review this bulletin in its entirety prior to beginning any repair
work.
As required by federal law, dealers must not deliver new vehicles for sale or for lease to customers
until all open recalls have been performed. Dealers must also perform all open recalls on used
vehicles, demo, and rental vehicles prior to placing them into customer use and whenever an
affected vehicle is in the shop for any maintenance or repair.
Access the “Vehicle Information” screen via WEBDCS to identify open recalls.

Description: The transmission electric oil pump for the Idle Stop & Go System (“ISG”) in certain
vehicles listed below may have been assembled with printed circuit boards (“PCB”) that were damaged
during manufacturing by the oil pump controller supplier. A damaged capacitor on the pump controller
PCB could impact electrical operation leading to heat damage to the electric oil pump circuit board,
connector, and wiring harness. The heat damage at the pump increases the risk of a vehicle fire in
addition to a potential Controller Area Network (“CAN”) communication disruption for multiple onboard
controllers.
This bulletin provides the procedure to check the ISG Electric Oil Pump (EOP) controller specification
and replace it if necessary for Palisade (LX2). For Sonata (DN8) and Tucson (NX4), 100% replacement
is required.
