If you suspect counterfeit wire, use the PDF's test methods:
Automotive parts — Environmental conditions and testing for electrical and electronic equipment — Part 4: Climatic loads
: Simulates high-humidity environments to check for structural swelling, insulation degradation, and latent short circuits.
is a technical standard established by the Society of Automotive Engineers of Japan (JSAE) under the Japanese Automobile Standards Organization (JASO) umbrella. The standard is titled:

Specialized automotive tests such as dustproof, waterproof, and solar radiation testing. Context in the JASO D014 Series
Given that JASO (Japanese Automobile Standards Organization) issues these standards, they are primarily aimed at the Japanese automotive market. However, the standards can also gain international recognition and application due to the global nature of the automotive industry.
JASO D 0144 establishes a standardized method for testing the durability and reliability of automotive electrical and electronic devices when exposed to sustained high temperatures and high humidity.
While full copies of JASO standards are generally proprietary, they can be purchased through the Society of Automotive Engineers of Japan (JSAE) or accessed via technical documentation providers like Test Navi and Scribd . If you suspect counterfeit wire, use the PDF's
Using wiring that adheres to JASO standards is not merely about compliance; it is about performance:
To check for degradation, thermal deformation, or functional failure. 2. Low-Temperature Endurance (Cold)
Evaluating corrosion resistance against saltwater (JIS Z 2371).
: Testing requirements vary depending on where the part is installed (e.g., the passenger cabin vs. inside the engine compartment). Determine "Z" Ratings JASO D 0144 establishes a standardized method for
The thin-wall insulation of JASO D0144 requires specific crimp terminals and tools. The PDF often refers to JASO D609 (for terminals). Using a standard ISO terminal on a JASO wire will cause "insulation crimp" failures (the crimp grabs air, not wire).
The official and correct designation of the standard is – note the hyphen before "4". The searched term "jaso d0144 pdf" omits this hyphen, but it invariably points to this document.
For Tier 1 and Tier 2 automotive suppliers, compliance with JASO D0144 is often a prerequisite for doing business with major Japanese automakers like Toyota, Honda, and Nissan. Adhering to these standards reduces the risk of costly recalls and enhances brand reputation for reliability. When a company references "JASO D0144" in its product datasheet, it signals to the buyer that the component has undergone rigorous, standardized validation. How to Access the JASO D0144 PDF
This translates to: "This standard describes the climatic loads that may affect electrical and electronic systems/components when they are installed inside or outside an automobile, and specifies the corresponding test procedures and requirements."
