    G15203868
  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).
  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.
    G15203869
  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.
    G15203870
    G15203871
    G15203872
  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.
    G15203873
  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.

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.
    G15203874
    NOTE:
    • 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.
  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.
    NOTE: 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.
  3. If the dash panel insulator assembly was found to be affected by water contact during the initial inspection, remove and replace the dash panel insulator assembly. Refer to TIS, applicable model and model year Repair Manual for instructions.
G15203875

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.

CAUTION:
  • Wear the required PPE (N95 certified respirator, safety goggles, AND protective gloves).
  • Ensure the vehicle is in a well-ventilated area, preferably in an area that has good airflow/circulation and is NOT enclosed.
  • Avoid scratching or damaging the sheet metal surfaces, as these areas will need to have NEW floor silencer sheets applied once the remediation is complete.
  • Do NOT use grinders, abrasive discs, or other similar tools to remove the material, as this can damage the anti-corrosion protection on the sheet metal surfaces.
  • Once removed, place all LASD debris in a plastic bag, seal the bag, and dispose of as normal refuse/garbage per EPA guidelines. (Do NOT use a vacuum to remove debris or old material left over from the removal process.)
  • If equipped, remove the cabin air filter and discard. A NEW high-performance charcoal filter should be installed once the entire remediation process has been completed. There should NOT be a cabin air filter installed in the HVAC during the remediation process.
  • To minimize the potential for damage to the threshold areas of the vehicle, it will be necessary to protect those painted surfaces. See step 1 in the Inspection Procedure for more details on this process.
  • Avoid removal of the urethane seam sealer where sheet metal panels join. If the urethane seam sealer has been removed during the LASD removal process, it will be necessary to reapply as needed AFTER the remediation process is complete.
G15203876

The appearance of LASD (color, texture) may vary (smooth vs. rippled) depending on the vehicle and application method.

G15203877

LASD Removal Procedure (continued) 

  1. Remove ALL LASD from the floor pan of the vehicle, including the cargo/trunk compartment, using a flat-bladed plastic scraper and a heat gun.
    G15203878
    NOTE:
    • Using a flat-bladed plastic scraper and a heat gun is the ONLY approved method for removing LASD.
    • Ensure ALL LASD is removed.
    1. Select a square area approximately 6 in. by 6 in. and begin heating the LASD with the heat gun for approximately 30 seconds.
    2. Check the heated sound deadening material with the plastic scraper to determine if it is pliable enough to remove.
      1. If the material is soft enough to remove, use the plastic scraper and remove the selected area.
      2. If the material is still too hard to remove, use the heat gun for an additional 30 seconds to see if the LASD is ready for removal. Keep track of the length of time necessary for effective sound deadening removal and adjust as needed.
      G15203879
      NOTE: Do NOT overheat the LASD. Heat the LASD just enough for it to become pliable.
    3. Continue this procedure until ALL LASD is removed from the vehicle, including the cargo/trunk compartment.
    G15203880
  2. Once removed, place ALL LASD debris in a plastic bag and dispose of it as normal refuse/garbage per EPA guidelines. Use a whisk broom and dustpan to remove ANY small debris on the floor of the vehicle.
G15203881
CAUTION: ALWAYS use proper PPE per current EPA guidelines.
NOTE: Do NOT use a vacuum to remove the debris left over from the removal process.

PREPARATION FOR SERVPRO™ REMEDIATION PROCEDURE

Prior to the remediation being performed, the instrument panel/dash pad and HVAC MUST be reinstalled and the HVAC made operational. If they were removed during the disassembly process to allow for installation of a NEW dash panel insulator assembly and have NOT been reinstalled, they must be reinstalled at this time. Reassemble the instrument panel/dash pad and confirm that the HVAC is operational. Do NOT install the center console or HVAC floor ducting/ductwork during this procedure. Refer to TIS, applicable model and model year Repair Manual for instructions.

  1. Adjust the climate control settings.
    1. Set the HVAC system vents to dash and floor vents. Do NOT set the HVAC system vents to defrost mode.
    2. Set the temperature to the medium setting (ambient temperature).
    3. Ensure the controls are NOT set to "Auto."
  2. Prepare ALL seat belts.
    1. Pull the seat belt from the retractor until it is fully extended.
    2. Hold the seat belt from the point closest to the retractor and fold over approximately 12 in. of seat belt back onto itself as shown.
      G15203882
    3. Continue to fold the seat belt onto itself until the entire seat belt assembly can be held in one hand as shown.
      G15203883
    4. Using a plastic/rubber-tipped clamp, place the clamp onto the top of the folded seat belt so it is secured and fully extended during the remediation process as shown. For vehicles equipped with second or third row center seat belts that are housed in the seat assemblies or roof, the same process of extending, folding, and clamping the seat belt should be performed.
    G15203884
  3. Complete step  2 for ALL the remaining seat belts.
    NOTE: It is recommended that the technician photograph the vehicle interior to document the preparation condition of the interior BEFORE the remediation is performed.

NOTE:
  • An email to TMNA HQ should NOT be sent until the vehicle has been FULLY prepped and is ready for the remediation services to be performed.
  • If a request to TMNA HQ is submitted and the vehicle preparation has NOT been fully completed, the dealer/requesting facility is at risk of not being able to have the remediation services performed on the vehicle at the requested time and being charged with a service-call fee.

POST REMEDIATION PROCEDURES

Once the remediation process has been performed by SERVPRO™, follow the steps below to prepare the floor pan of the vehicle for reassembly of the vehicle interior.

NOTE:
  • Post remediation procedures should NOT be initiated until the dealer has received a clearance report from ServPro Commercial LLC™ stating that vehicle has been cleared and successfully remediated.
  • The invoice will be sent directly from the ServPro Commercial LLC™, not the local franchise accounting group, and will be separate from the clearance report. The invoice should be paid by the dealership within 30 days of receipt of invoice or risk rejection of future services.
  • Post remediation procedures should be performed AFTER the remediation has been completed.
  • Do NOT apply seam sealer or floor silencer sheet to the floor pan BEFORE the remediation process is performed.

Urethane Seam Sealer Application Procedure

  1. Was urethane seam sealer removed during the LASD removal process?
    • YES -  Continue to step 2.
    • NO -  Go to the Floor Silencer Sheet Installation Procedure subsection.
  2. Ensure the floor pan has been cleaned properly and is free of any dirt, oil, grease, or other debris.
  3. Apply the urethane seam sealer using a brush to ALL locations where the urethane seam sealer was removed during the LASD removal process.
    G15203885
  4. Allow the seam sealer to dry for a MINIMUM of 1.5 hours.

Floor Silencer Sheet Installation Procedure

The floor silencer sheet will need to be applied in the areas where LASD was removed to restore the sound deadening function of the removed material. The floor silencer sheet comes in two different thicknesses (1.5 mm and 3.0 mm). Refer to the applicable Collision Repair Manual or New Car Features for details on the required thicknesses for specific locations.

NOTE: When the original LASD material exceeds 3 mm in thickness, application of multiple layers of floor silencer sheets may be necessary to match the original specification found in the Collision Repair Manual or New Car Features.
  1. Draw a rough outline of the area to be covered onto the appropriate thickness of the floor silencer sheet.
  2. Cut the floor silencer sheet slightly larger than the rough outline drawn using scissors, a utility knife, or other suitable cutting device.
    G15203886
    CAUTION: Use caution with ANY type of cutter to avoid injury.
  3. Spray 3M™ General Trim Adhesive to the back side of the floor silencer sheet and allow it to air dry for five minutes.
    G15203887

    Floor Silencer Sheet Installation Procedure (continued) 

  4. Place the floor silencer sheet onto the selected area and press it into position.
    G15203888
  5. Use a heat gun to evenly heat the floor silencer sheet over the entire surface to a temperature of 180°F - 240°F (82°C to 115°C).
    G15203889
    CAUTION: Use caution and wear proper PPE when operating a heat gun to avoid burns.
  6. Force the floor silencer sheet down into the floor pan making sure to form it into ALL the recesses as shown.
