Toyota has issued a Collision Restore Facts Bulletin (CRIB) reinforcing its position on some critical collision mend subject areas, including the prohibition from the use of heat to straighten entire body and frame elements, and right welding techniques. The bulletin applies to all Toyota, Lexus, and Scion motor vehicles.

Toyota’s updates serve as a reminder that repairers must look at for the authorized OEM process for each job, every single time, regardless of company. The bulletin should really not be regarded all-inclusive or a substitute for teaching, Toyota cautions.

Simply because substantial strength sheet steel is utilized for structural physique and body factors, it is essential that heat not be employed in repair service strategies, Toyota mentioned. Heat can change the crystalline composition of the metal, causing a sizeable lessen in strength, Toyota warned. Heat also damages the panel’s zinc coating, reducing its resistance to corrosion.

Weakened doorway intrusion beams should be replaced, and not fixed, Toyota claimed. Beams are designed to soak up, channel and dissipate strength in the party of a collision, and will no for a longer time perform as supposed if fixed. Total door substitute is named for when a beam is harmed, Toyota claimed.

For similar causes, destroyed bumper reinforcements have to be replaced, and not repaired, Toyota mentioned.

Frequently talking, body and frame deformations that are not able to be returned to first shape by cold straightening – pushing, pulling, and hammering – are labeled as kinks, in accordance to Toyota. Factors that are kinked will have to be replaced. Any deformation that can be addressed by cold straightening is categorised as a bend.

Welded body factors are to be installed working with fuel inert arc welding/metal inert fuel (MIG) approaches, Toyota explained. It specifies the use of ER70S3 welding wire and encourages repairers to ensure appropriate weld location and penetration with apply welds. Repairers have to not weld in excess of factory weld beads, and must clean afflicted repair service surfaces and use epoxy primer and matching topcoat, Toyota mentioned.

The only approved welding technique is a butt joint with out backing, Toyota reported. It warned that employing sleeves and inserts will interfere with crash electricity management types. Repairers are directed to guarantee correct root-hole, weld configurations, and penetration with practice welds, and to minimize and sign up for only in spots specified by the OEM.

Just before executing any electrical welding, experts need to transform off the vehicle’s ignition and take out the damaging link to its 12-volt battery, Toyota reported. Any ECUs in just 18 inches of the weld web-site should be taken off, and the key supplemental restraint process (SRS) laptop connector must be unplugged. Toyota advises repairers to hold out at minimum 90 seconds after these techniques to get started welding.
