damage, fault type G5).

Fault type:

^ 47 corroded/oxidized

^ A4 stretched

^ D6 sluggish

^ F4 no power flow

^ G5 noises in complete vehicle speed range

For damage code 28224 helical gear set/spur gear set, the fault type "36 noises" is replaced by "46 howling" (this fault type is to be used, for

example, for gear set howling).
