    PSM operation

    Perhaps someone with technical experience could answer my query.

    When do any of the PSM functions work?

    They work only when the PSM light flickers or do they work in other occasions invisibly?

    I was told that the light only flickers in extreme situations but the electronics work unobtrusively all the time correcting more minor stability issues. What is the truth?

    Re: PSM operation

    Well the PSM englobes the ABS, ABD and ASR and these may work independantly as well and may act in instances were the whole PSM yaw correcting system is not kicking in, i.e. the ABS can kick in because of tire slippage under braking yet the PSM light does not necesarily come on. 

    I guess this is what they may be referring to?  but if the PSM needs to correct oversteer or understeer, I should think the light comes on always though, because that is PSM's "as a whole" job by using ABS, ABD, etc. So parts of the PSM system are always working without the light being on, but not the PSM "system". And conversly, if you switch PSM off, the ABS and ABD are still working. Semantics I guess....

    Thanks! So like in the case of ABS, equally the ABD and the ASR could correct some minor occurrences without the light coming on.

    Re: PSM operation

    AFAIK yes, because the ABD for example, works as an electronic differential for the front and rear axles, and when you disconnect the PSM for example, the ABD however is still ON always, independant of the PSM. Same as ABS. But I'm not 100% sure for the ASR though.
