IV. BACKGROUND AND COMPONENTS
Toyota has received a number of reports regarding Frame Corrosion on
2005 – 2010 model year Tacoma vehicles, 2007-2008 Tundra vehicles,
and 2005-2008 Sequoia vehicles. In these reports, customers have
indicated that vehicles operated in specific cold climate areas with high
road salt usage may exhibit more-than-normal corrosion to the vehicle’s
frame. This condition is unrelated to and separate from normal surface
rust which is commonly found on metallic surfaces after some years of
usage and/or exposure to the environment.

• Because of variations in State and local laws, dealerships conducting H0F in certain states may

require government approvals prior to starting the campaign. Depending upon the state,
dealerships also may be subject to restrictions on the number of vehicles to which the CRC can
be applied in any single day, week, or month. Please refer to the Dealer Information Packet and
any Supplements for important information about any such approvals or restrictions that may
apply to your dealership. Your dealership must adhere strictly to these requirements.
• For a complete list of Site Selection Guidelines, Fire, Building, and Zoning Codes information for
your state, please refer to the Dealer Information Packet as well as any Supplements. Please
ensure your dealership complies with all regulations and all issued packets/instructions.

Note: Vehicle frame inspection is performed under WEP ZH9, for inspection instructions go to WEP ZH9
Technical Instructions.

VI. FRAME APPLICATION WORK PROCEDURE

Due to the flash point of the CRC materials, allow sufficient time for the vehicle and
exhaust to cool down before beginning the application process. By following the
FRAME APPLICATION WORK PROCEDURE in these Technical Instructions, the
vehicle will have additional time to cool before the CRC’s are applied. Please refer to
the SDS (Located in the Appendix) for flash point temperatures.

WORK AREA SETUP (SUGGESTED)

1. INITIAL SETUP CONSIDERATIONS & GUIDELINES

Ex

d

a) Work with your Service Manager to locate a dedicated work area and lift with the following
requirements.
i. In well ventilated area.
ii. Away from other vehicles to minimize the possibility of overspray.
iii. In a location that can be sectioned off by partitions.
iv. In an area that provides sufficient distance from neighboring stalls.
v. In an area that meets the minimal space requirements as outlined in Site Selection Guide of the
Dealer Information Packet (provided at the launch of H0F) and any Supplements.
• A fire extinguisher, rated “B”, “AB” or “ABC”, must be located in an area that is within
at least 30’ of application area.
• Important Reminder: Because of specific fire and building code requirements, make
sure to review the Site Selection Guide of the Dealer Information Packet (provided at
the launch of H0F) and any Supplements to ensure that the area where you will
conduct the CRC application is compliant with the appropriate requirements.

Note: area set up may vary depending on dealership layout. The following information is just one
example of how an area might be set up for frame CRC application.
