UNDERBODY CORROSION PREVENTATIVE SERVICE
(SERVICE CAMPAIGN 991)
 IMPORTANT
Dealers must perform this service campaign on all affected vehicles prior to customer retail delivery
and whenever an affected vehicle is in the shop for any maintenance or repair.
Access the “Vehicle Information" screen via WEBDCS to identify open Campaigns.
Description: In some areas, a vehicle’s underbody may exhibit corrosion due to road salt usage. As
a preventative measure, cavity wax coating is applied to the internal surfaces of underbody
components, and an undercoating spray is applied to the bottom exterior surfaces of specified
underbody components. This bulletin describes the procedure to perform this preventative service on
certain Genesis Sedan (BH), Equus (VI), and Genesis Coupe (BK) vehicles.

6 digits of the VIN and date of repair on a piece of paper. Ensure the VIN and date of repair
are clearly visible. Finally, please ensure all captured pictures are completed according to
the steps in this TSB and uploaded to STUI. All claims submitted that have illegible,
incomplete, missing, or incorrect picture(s) are subject to debit.

 IMPORTANT
There are circumstances under which vehicles that are not currently registered or have never been
registered in a “salt belt” state may be eligible for this service campaign. These circumstances
include:
• Vehicles that were relocated into a “salt belt” area and/or
• Vehicles registered in a “non-salt belt” state and driven in a “salt belt” area
If it is determined that an owner of a vehicle within the affected VIN production date range
relocates or has operated their vehicle in a “salt belt” area, the dealer should perform this
procedure at no cost to the customer. The dealer must submit a Prior Approval request before
starting repairs.

Vehicle Preparation:
1.
Wrap the brake assemblies with plastic
bags to protect them from overspray. Use
tape to secure the plastic in place. Leave
the banjo fitting area exposed, as shown.
! CAUTION
•
The brakes must be sufficiently cooled
before it is wrapped.
May cause burns and melt the plastic.
•
2.
Wrap large plastic bags around the
wheel/tire/brake assemblies to protect them
from overspray. Use tape to secure the
plastic in place.
3.
Wrap the exhaust areas adjacent to the
front and rear sub-frames with plastic bags
to protect them from overspray. Use tape
to secure the plastic in place.
! CAUTION
•
•
The exhaust must be sufficiently cooled
before it is wrapped.
May cause burns and melt the plastic.

Applying Cavity Wax:
! DANGER
•
•
•
This procedure must be performed in a well-ventilated area.
Must wear safety goggles, face protection, and gloves. Rinse eyes with water or skin
with soap and water. Do not inhale spray. Seek medical attention if needed.
Flammable & pressurized. Do not spray near flames, sparks, or heated areas. Do not
pierce can.
Apply the cavity wax at each of the locations noted in the following steps.
Generally for coating interior surfaces, insert the “inside” nozzle as deeply as possible at each point of
entry. Spray the cavity wax while simultaneously rotating the nozzle, and slowly pulling the nozzle
out. Continue this rotating/pulling motion until the pink tubing is seen coming out of the hole. The
pink tubing indicates there is about 50mm of tubing left until the end of the nozzle. Stop spraying
when the pink tubing is seen.
Generally for coating exterior surfaces, use the “outside” nozzle, provided with the wax gun. Use this
nozzle if the inside nozzle is too large to access the internal cavity of the components.
1.
Use the marked areas as a guideline to
insert the cavity wax nozzle. Additional
access into the internal cavity of the
components might be possible.
TSB #: 23-01-034H

Wipe the excess wax off the exterior
surfaces of the components.
