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 Dealer Informaton 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, and fire, building, and zoning code information for
your state, please refer to the Dealer Information Packet (provided at the time of launch) as well as
any Supplements. Please ensure your dealership complies with all regulations and all issued

a) Lower and raise the spare tire with the tools provided with the
vehicle and ensure it is operating properly.
Note: Do not operate the spare tire carrier with an impact
because damage will occur to the spare tire carrier.

b) Completely lower the spare tire and remove it from the carrier
2. VISUALLY INSPECT THE SPARE TIRE CARRIER PLATE FOR RUST COROSSION

c) Inspect the bottom edge of the spare tire carrier plate for rust corrosion around the perimeter; confirm that
rust corrosion does not cover the entire perimeter.

Note: If the spare tire passes the inspection
CRC will be applied to the spare tire carrier plate.
• If the spare tire carrier does not pass any of the inspection criteria, the spare tire
carrier will need to be replaced.
• Do not replace the spare tire until all rust has been removed from the frame and
you have confirmed it has passed the final frame inspection (section VI. B.1.b.)

1. PREPARE THE VEHICLE

LS

A.

d

Due to the flash point of the CRC, allow sufficient time for the vehicle and exhaust to cool
before beginning the application process. By following these Technical Instructions, the
vehicle will have time to cool before the CRC’s are applied. Please refer to the SDS
(located in the Appendix) for flash points.

a) It may be necessary to pressure wash the vehicle’s frame,
depending on its cleanliness.
Note: Time has been allotted to pressure wash the frame in
the flat rate time.
b) Place the vehicle on the lift and raise the vehicle.
Once the vehicle is raised to the desired height,
install screw jacks to the front & back of the vehicle.

c) Remove the wheels.
Note: Mark the wheel assemblies with tire to ensure they are
put back in there original location.
d) Remove the engine under cover.
e) Remove the rear quarter panel mudguard LH/RH side.
f) Remove the rear bumper cover assembly.
g) Cover any identifying label (i.e., VIN label, etc.) on the frame
with tape.
h) Cover all exposed electrical connectors with tape to protect from
over spray.
2. REMOVE RUST FROM THE FRAME AND CROSS-MEMBERS.
a) Using a scraper or chisel remove all loose rust and rust scales
from the frame and cross-members areas identified in blue.

Note: The use of power tools is permissible during the
cleaning process. Toyota has found air scalers to work very
well.

Power Tools are Permissible

b) If rust perforation of 10mm or larger is found during the rust
removal process, confirm that it is located in the green inspection
area (p. 10) and proceed to Frame Replacement TI.

To adequately clean the rear cross members and
frame assembly, ensure that the rear bumper cover
assembly has been removed.

Notes:
• Make sure to wear protective eyewear, gloves, ear plugs
and a dust mask when removing rust and cleaning frame.
• Be careful not to damage the wire harness or brake lines.
• Be extremely cautious not to injure your hands.
• DO NOT scratch or remove the identifying labels (i.e., VIN
label, etc.) from the frame.
