  • Idle Validation Switch on 09 X3

    Posted by atanas on December 7, 2018 at 12:37 pm

    Hey guys Happy holidays

    I cannot locate the idle validation switch on this bus 09 X3-45. in manual it shows nothing. I think it is the Potentiometer on the throttle pedal. I found this on another bus online.

    I have a another Potentiometer here in stock. i installed it but still get same fault code

    idle validation switch open circuit SPN 558

    I’ve responded to a few questions so far. The other day your bus was a 2018 and today it’s a 2009.

    Are you a tech at a bus company ?

    Apex,

    We have no problem with your participation on the forum. I regret we are unable to answer or comment on some of your questions, but that is because most of us are not skilled or trained technicians and blurting out a guess might just confuse an issue even more.

    What we would like is someone with your obvious expertise is participation in answering questions, but also providing us with information on how you ultimately solved some of the problems and questions you posted.

    You are always welcome.
