    [h=2]Volvo Truck ABS Trouble Code Help[/h]
    I have a 2012 Volvo VNL780 with a TCS light that stays on all the time. Trouble codes (active) are MID 136 SID 78 FMI 2 and MID 136 SID 77 FMI 7. Can anyone shed any light on what I need to look for to correct these?
    VIN is 4V4NC9TJ7CN558798. Engine is ISX. Any help would be greatly appreciated.​

    This code is much cheaper, just pressure sensors wiring!

    Thank you . I will check the sensor connections. Those are located in the airbags aren't they?

    Depending on ABS/EBS configuration

    If u have truck with "traditional" foot brake valve demand sensors are used, if full EBS - sensor is built in brake valve.
