Parts Information:
•
•
Please refer to TSB 23-01-036H-1 (or latest version) for the latest parts information.
Please consider the following:
• HECU Unit Assemblies (various part numbers): On CSP (Critical Parts Supply), VIN restrictive.
Dealer will require a valid service campaign 990 VIN to order the part. Due to a limited quantity of
parts inventory, this will assure affected customer vehicles encompassed in the campaign receive
priority part allocation.
• Multimeter DT-830D+ (HK589-DT830QQH): Each dealer was previously shipped 1 multimeter for
this campaign, with arrivals at dealerships starting 05/03/23.
Customer Mailing:
Owners of the affected vehicles are expected to be notified via First Class mail starting by end of June 2023 of a repair
available for their vehicle.
Customer Talk Tracks:
“As a regular practice, every visit to our Hyundai dealership we check your VIN number to see if your vehicle has any open
campaigns or recalls. We did confirm that your vehicle has an open service campaign which requires we inspect the Hydraulic
Electronic Control Unit (HECU) to verify if a fluid leak exists. In some cases, vehicles may exhibit the Electronic Parking Brake
(EPB) warning light on due to brake fluid entering the HECU (Hydraulic Electronic Control Unit) electrical connector. Even if a
fluid leak is present, the operation of the Electric Parking Brake (EPB) operation is not affected. If the inspection reveals that
there is a leak, we will replace the HECU for you at no cost and provide you with a Service Rental Car (SRC) if needed.”
