Odor Remediation After Water Intrusion
Introduction

Some 2005 – 2022 model year Toyota vehicles that have undergone water intrusion may exhibit a
condition in which a musty smell is present. Follow the procedures in this bulletin to remediate the
odor and address this condition. The purpose of this service bulletin is to provide general guidelines
and procedures for odor remediation. This service bulletin provides a guide on how to prepare the
interior of the vehicle prior to an odor remediation being performed, as well as contact information
for an approved vendor who will arrange the remediation, and instructions on how to prepare the
interior of the vehicle for reassembly once the remediation has been completed. Refer to all model
and model year specific Repair Manuals and the EPA (Environmental Protection Agency) website
for the most up-to-date safety and precautionary guidelines. This service bulletin is to provide a
general overview and direction for the odor remediation process.
NOTE
 The procedures described in this service bulletin are NOT applicable to vehicles that have
undergone a severe freshwater or saltwater intrusion. Such intrusions could be encountered with
floods, storms, hurricanes, typhoons, or other incidents where the vehicle has been submerged or a
significant volume of water has entered the interior of the vehicle.
 This bulletin is NOT applicable for general HVAC odor concerns. This bulletin has been developed to
address water intrusion-related odors ONLY and should not be used to address HVAC-related
odor concerns.
 BEFORE beginning the procedures provided in this service bulletin, the source of water intrusion
MUST be identified AND repaired in conjunction with odor remediation. This bulletin does NOT apply if
the source of the water leak has not been identified and repaired.
 Follow repair requirements as per Warranty Policies 4.21 and 8.14.

*Liquid Applied Sound Deadener.
**For removal of the LASD, time studies have shown the following: Small vehicles and trucks ~8 – 10 hours and mid to
large SUV’s and vans ~10 – 12 hours. Utilize the Electronic Flat Rate Manual as a guideline to aggregate labor times
associated with the removal of the interior, taking into consideration overlapping labor. Time Punches and additional
documentation will be required (see Warranty Policies 4.21 and 8.14).
***The OFP should be the part number of the component that resulted in the water intrusion condition. If the root cause is
NOT due to a specific component that has a part number (e.g., seam seal leak on bulk head), the part number of the
related component should be used.
****Identify the appropriate T2 code.
*****Use sublet type “EC” for SERVPROTM odor remediation services. For repairs sublet to a body shop, use sublet type
“ZZ” (See Warranty Policy 8.22).

APPLICABLE WARRANTY
 This repair is covered under the Toyota Basic Warranty. This warranty is in effect for
36 months or 36,000 miles, whichever occurs first, from the vehicle’s in-service date.
 Warranty application is limited to occurrence of the specified condition described in
this bulletin.
 Per Warranty Policy 5.2, only one warranty claim per warrantable condition will be accepted

Odor Remediation After Water Intrusion
Inspection Procedure
CAUTION
ALWAYS use proper PPE per current EPA guidelines.

1. Prepare the door opening thresholds (e.g., door sills and B and C pillars).
A. Apply two layers of blue painter’s tape to ALL door opening thresholds as shown. This will
help minimize damage to the vehicle’s painted surfaces during removal and reinstallation
of the interior parts.
Figure 1.

2. Remove ALL parts surrounding the source of the water leak to complete a thorough
inspection of the vehicle. Due to the variety of possible water leaks, this process will vary
from vehicle to vehicle. In most cases, these items include but are not limited to:


The right and left front seat assemblies.



The rear seat assembly.



The second and third row seat assemblies (if applicable).



The lower trim panels (e.g., scuff plates, kick panels, pillar garnishes).

Inspection Procedure (continued)

3. Complete a thorough inspection of the entire interior floorboard areas to ensure ALL affected
areas are identified.
CAUTION
ALWAYS use proper PPE per current EPA guidelines.
Figure 2. Floorboard Inspection

4. Inspect ALL soft parts for organic matter growth and/or staining that would indicate
water contact.
NOTE
 Soft parts include items that DO HAVE an absorbent quality that will require them to be removed
and replaced with NEW parts if they have come into contact with moisture.
 Keep ALL soft parts that will be replaced away from the parts that will be reused.
Soft parts include:
 Floor mats.
 Carpet/Carpet padding/Jute padding.
 Insulated pads/Styrofoam pads.
 Dash panel insulator assembly (located behind instrument panel/dash pad).
 These parts should NOT be reused and require replacement with NEW parts once the
remediation has been completed.

5. Inspect ALL hard parts that may have been exposed to surfaces that have had direct contact
with water or that have evidence of organic matter growth.
NOTE
Hard parts include items that DO NOT HAVE an absorbent quality and do NOT need to be replaced.
ALL hard parts should be organized together in an accessible location near the vehicle, as they will
be treated together as part of a later cleaning step performed by SERVPRO™. Hard parts include:
 Plastic garnishes/trim panels (scuff plates, kick panels, center consoles, etc.).
 Plastic ductwork.

6. Inspect the dash panel insulator assembly
along the base of the instrument panel and
floorboard area for ANY signs of water or
organic matter growth. Perform this
inspection on BOTH the driver AND
passenger sides of the vehicle. If ANY sign
of organic matter growth and/or staining
that would indicate water contact has
occurred is found, the dash panel insulator
assembly will need to be replaced.

Odor Remediation After Water Intrusion
Disassembly Procedure

Due to the differences in vehicle design and the various water intrusion conditions that may
occur, specific steps for disassembly of the vehicle interior may vary. The purpose of the
Disassembly Procedure in this service bulletin is to provide general disassembly guidelines to
prepare the interior of the vehicle for remediation services.
NOTE
 Vehicles with second and third row seats will require removal of ALL seats in order to properly access
and remove the LASD from the vehicle, as well as ensure the entire vehicle is remediated during the
SERVPRO™ remediation process.
 For hybrid vehicles, the hybrid battery should be removed BEFORE the rest of the disassembly
procedure. Please reference applicable Repair Manual and be sure to follow all recommended safety
precautions for hybrid battery handling.

1. If equipped, remove the cabin air filter
and discard.

Figure 7. Cabin Air Filter
1

NOTICE
 There should NOT be a cabin air filter
installed in the HVAC during the
remediation process.
 A NEW high-performance charcoal
filter should be installed AFTER the
entire remediation process has
been completed.

The Cabin Air Filter Should Not Be Installed in
the HVAC During the Remediation Process

2. Remove ALL remaining interior components that cover the LASD located on the floor of the
vehicle. Refer to TIS, applicable model and model year Repair Manual for interior
component removal.
NOTICE
If the dash panel insulator assembly requires replacement, it should be removed and
replaced with a NEW part BEFORE remediation of the vehicle. On most vehicles,
replacement of the dash panel insulator assembly requires removal of the instrument
panel/dash pad assembly and the HVAC ducting. Do NOT attempt to cut out affected areas or
treat the dash panel insulator assembly.

NOTE
In most cases, the door panels and headliner can remain installed in the vehicle UNLESS they show
evidence of water contact.

LASD Removal Procedure

LASD is a vibration damping coating that is used on the floor of vehicles to reduce road noise. To
maximize the effectiveness of the remediation, LASD removal is required prior to the remediation
process being performed.
