Appropriate modifiers are added to a base word until an object or system is uniquely specified within its context. Add modifiers as necessary or as desirable within the context, in the order of most significance to least significance. The most significant word will be the base word, which denotes the basic function of the object.
The most significant modifier will be adjacent to the base word, the second most significant will be next to that modifier, and so on until the least significant modifier is added.
For the sake of future clarity, an additional modifier can be added to a name at any time, even if there is no present conflict with another object name. When naming an object, it is tempting to choose the first modifiers according to the initial purpose for which the object was designed, but this will not always result in the name which is the most helpful in the long run to a service technician.
The information a technician needs is most often supplied by a term which describes a functional attribute, not purpose. See Table 1 for naming methodology of describing objects and systems using modifiers attached to base words. Table 1 — Modifier usage example Modifiers What is its purpose?
Where is it?
Which temperature? What does it sense? Base words which describe non-electrical objects e. When using a common multiple word modifier, see SAE JDA to be sure that the modifier is acceptable or if it should be replaced with a more precise term.
Specific information like this is provided by modifiers that are added to the base word. The following are examples of base words: diode, engine, module, motor, pump, relay, sensor, solenoid, switch, valve.

The base word is always a noun and the last term in a name. ISO E 6.
The range of modifiers is not limited and is used as necessary to uniquely describe an object in light of present knowledge, past experience and potential future conflicts. Although modifiers are used as adjectives, they are not necessarily terms which would normally be classified as adjectives.
Both modifiers are nouns functioning as adjectives because of their positions.

System modifiers can be added to object names to describe an object's purpose. Add an appropriate technological modifier to a name only when it describes the primary difference between two objects.
A technological term should be the first modifier conversationally farthest from the base word, the position of least significance , unless a directional modifier is also present. It is preferable to create a name first and its shortened form later, rather than the other way around.
Treat the individual acronyms, modifier abbreviations, and base-word abbreviations as words, separating them by space characters. While abbreviations are useful in text where space is limited, acronyms are particularly convenient for shortening verbal communication in addition to written materials.
For this reason, acronyms are often pronounceable, which also makes them easy to remember. They are especially useful if a name is long and bulky both on paper and in conversation. Acronyms and other modifiers may be combined in any meaningful order to modify a base word.
Also, avoid creating new acronyms by adding letters to those that already exist. Instead, use additional modifiers.
All of the letters of an acronym should be capitalized. Acronyms should not contain periods. Until an acronym is widely well-known, it should be accompanied by the spelled-out form when necessary for accurate reader comprehension in any given context. In the very rare cases of strong historical meaning across all manufacturers, the rules for naming and acronym usage may be broken.
However, vehicles no longer necessarily use a separate air injector reactor, but instead might have additional air injected to the catalytic converter. Unlike an acronym, an abbreviation should have only its first letter capitalized and should end with a period. Wire colours are an exception to the rules of capitalization and punctuation. They most frequently index base words, following each by its modifier s to enhance users' retrieval.
This document allows the designer flexibility to choose the indexed word s , while describing, in detail, the methodology for the conversational word order in text and illustrations. This section includes naming objects with base words, modifiers and technological terms , naming systems and building shortened names. An alphanumeric descriptor is not recommended for general use, but can be 6? ISO — All rights reserved ISO E built from a recommended term by replacing position modifier words with numeric digits, and omitting certain self-evident letters.
Alphanumeric position modifiers in an alphanumeric descriptor should be positioned to follow the base word, rather than the conversational practice of preceding the base word.
Table 2 illustrates how several recommended terms and acronyms can be further shortened into alphanumeric descriptors.Alphanumeric position modifiers in an alphanumeric descriptor should be positioned to follow the base word, rather than the conversational practice of preceding the base word.
A technological term should be the first modifier conversationally farthest from the base word, the position of least significance , unless a directional modifier is also present.

The SAE J standard defines a method for requesting various diagnostic data and a list of standard parameters that might be available from the ECU. The information a technician needs is most often supplied by a term which describes a functional attribute, not purpose.
