    Good morning,
    I’ve just developed an issue with my 2010 d13 with ishift transmission. Driver arrived at shipper dropped his trailer in a dock and went to designated bobtail parking. After about 30 minutes there’s no throttle response when he put it in gear but when in neutral the throttle responds. No error codes and the abs and tcs light are not on. Any info as to where to look will be highly appreciated. Thanks in advance for any help!

    I would start by shutting truck off and looking at batteries, terminals corroded, corrosion on batteries. Lots of electronic modules that rely on good clean voltage. Secondly turn battery disconnect above batteries. Let sit 10 min or so and then turn back on. Have driver check for loose connections on batteries.
     
    bonous Thanks this.

    Thanks! The truck doesn’t have a battery disconnect switch but he have checked the battery connections no problem there, also he disconnected the negatives for about 30 minutes and reconnected them back and still no change. When in neutral the throttle responds but in gear it doesn’t.

    I suspect that is the stability control stepping in and taking the throttle away.
    Is there someone near that can scan it just in case its a simple fix?
    Alternatively open the fuse box and remove the ABS fuse and see if that gets
    the throttle back.
    To open the fuse panel pull the cup holder out part way and remove the two
    T20 head Torx screws then pull up on the plastic cover and cup holder.
    There is a map of the fuses on the bottom of the cover.
     
    bonous and jason6541 Thank this.

    May have some corrosion in wiring harness connectors at transmission, or a chaffed harness. Also could be an air issue. Those I shift trans are heavily reliant on air pressure and good clean dry air.
    But at this point without looking at the truck or plugging in I am of no further help. Good luck
     
    bonous Thanks this.

    You need to find someone to scan it for you.
