    real time clock is powered with small 3.6 v battery. It is Li battery used for ECM life. In electronic shops it is possible to solder new battery in and with DDRS you can set the clock

    SID 004 FMI 5 - broken ABS sensor wire, right rear wheel (you have Wabco ABS-E 4S4M system)

    Ty for response yea I found the problem for the wire In rear axle it's cut inside the drum somewhere I'm gonna fix it when I change the rear tires I can't get to it without removing the wheels but for the other fault I think I'm gonna leave it alone cause I heard it doesn't cause any problems for the truck. Does anyone know how to erase fault codes?

    freightliner dashboard reads codes as active, so fix cut wire with heat shrink and ABS code dissapeares

    Engine ECM code may be fixed in electronic shop. If you ignore bad clock battery it may leak acid and damage ecm iside. To desolder battery find shop with infrared solder station and ECM body heater, becouse if to heat battery only if may blow spiling acid on film and ECM be damaged out of repare

    Yes by all means replace the Abs sensor. Do not splice it back togeather! The Abs light will still remain on until you clear the active fault and then drive the truck a short distance. Make sure you check the air gap between the sensor and the exciter ring before you put the brake drum back on.

    push the sensor back with ring carefully to get minimal air gap but do it carefully to avoid ring be bent
