    PROBLEM IS SOLVED!!!!!!!!!
    There is two sensors for rear suspension pressure. The one on very top left if you are looking from the cab is rear suspension pressure for instrument cluster, marked as rear suspension pressure.
    The one which is for ABS module is on the very bottom left, marked as D2.

    Nice. I was going to send you this pic which shows the same thing but wanted to make sure it was valid for your build date. B58R is one but B177 is the one that signals the Bendix ecu. At any rate. Good find.

    Thank you. Very helpful picture. I figure out it by looking closer on the firewall from the engine side. There is T-connector for rear suspension airline to split pressure between two sensors. really hard to notice behind all wires and airlines.
    And one important things to notes. The damage was made couple months ago when I was searching for air leaks and sprayed firewall air fittings with dish soap water. Some water got inside the plug and cause corrosion.

    Having a similar issue, but the connectors look good, none of the air pressure gets displayed until I unplug the sensors and plug em back in then they work, turn the truck off and then on and they stop working again. Have no idea what's going on...

    Hello everyone!
    I'm in need of help in regards the TCS and ABS ( on the truck), please.
    The codes that I got on the computer are in the Brake ECU tab:

    MID 136 SID 89 FMI 2
    MID 136 SID 4 FMI 14

    My unit it's a 2012 Volvo vnl 670 ,Cummins isx ,13 speed.
    Vin CN 553443
    So the TCS light in the cluster it's solid ON, the switch on the dashboard it doesn't do anything if turned on/off.
    It started to be like this ,ON ,since I tried to enter the shop where the ground level was different, so I switched ON the front axle switch in order to move .Since then the TCS stayed on. While trying to switch it off from the button it doesn't do anything.
    I greatly appreciate your time and expertise into all your answers posted above. Hope you can help me.

    Thanks allot !
