This template contains an examples of how to fill out the FMEA. Furthermore, it contains a number of failure modes which are bothstarting points and examples for the failures to be covered in your team's FMEA. N)TE* N!t every #iven 'ai%ure may a$$%y t!every team&s E%e"tr!ni" Thr!tt%e C!ntr!%+ The #iven 'ai%ures may a%s! be in"!m$%ete ,ith res$e"t t! y!ur s$e"i'i" system+A 'ai%ures t! the %ist. i' a$$r!$riate '!r y!ur system+

hange the complete example given, i.e. !o.", to suit your system. Add missing failure modes with respect to your car's system.#e as complete as possible, adding any failures that affect the safety of your car, the driver, or other persons. #efore submittingyour FMEA please ma$e sure it is complete. This way you will avoid unnecessary delays and %ueries.

&nly add additional failures at the end of the list to $eep the numbering scheme of the original template. This ma$es reviewing thedocument much easier and thus faster. o not delete any failures, if they do not apply to your system. (ust write )oes not apply.)

or similar with a short reason why.

*n addition to completing the FMEA page, also complete the +ystem escription page so that the technical udges can understandhow your system wor$s and the components that are contained within it
