General

This annex provides a general method for defining the acceptable performance of electrical/electronic functions of automotive electrical systems during and after vehicle immunity test for electrical disturbances from narrowband radiated electromagnetic energy. This method is based on the following considerations:

a) a vehicle can include one or several functions (e.g. an electronic unit can manage front wiping, courtesy lighting and low beam lighting);

b) a function can have one or several operating modes (e.g. low beam ON, low beam OFF, courtesy lighting ON, courtesy lighting OFF);

c) an operating mode can have several statuses (I, II, III, IV) (e.g. in low beam ON operating mode, the status II can be associated to low beam OFF during disturbance application with automatic recovery of low beam after disturbance suppression).

The functional performance status classification is applicable to each function.
