2 Field ofa ppl cation

This International Stand rd a pl es to electronic sy stems including electronic control modules,as ociated

input sensor , output actuator and ind icator

The measurement rang es specified exclude certain dev ices for which specific test equipment is required

It do s not a ply to those sy stems which hav e bui t-n d iag nostic ca a i ties and do not require

For the purpose of this International Stand rd, the definitions of ISO4 92a ply

5 General requirements

W here the fu ctions to be tested are specified b the v ehicle man facturer, the test shal be car ied out in

ac ord nce with the man facturer’s instructions, which shal take into ac ou t the principles of5.1 to5.3

5.1 Acc s ibi ity of ele tronic system s

The electronic components of the sy stem to be tested shal be desig ned so that it is pos ible to make the

neces ary con ections to the test eq uipment Relev ant operational cir uits shal be easi y ac es ible and

identifia le for test purposes This ma be mad e pos ible throug h the input an output con ector or b

special con ector( s)

5.2 Sim ulation of vehicle g enerated input sig nals

I output sig nals hav e to be observ ed u d er specific operating cond itions, the pos ibi ty of substituting or

ov er id ing input sig nals is req uired

5.3 Sig nals in output l nes

Consid eration should be g iv en to the fact that, in some instalations, output l nes ma also serv e as input

lnes, and in that case shal conform to5.2
