Adams Car analysis failed (Toe out)

SamsonAkash
Hi guys, I am was trying to create an Baja ATV in Adams car. During acceleration analysis I get Toe out in front suspension geometry and it got steer itself even the steer input was locked. I was trying constant radius cornering and its getting failed. So please take a look at those video and have a look at my file and help me to solve my problem.
 
thanks in advance

    Hello, to check your model we need also templates and subsytems not just assembly.

    Too soft bushings? Try running with the suspensions and steering set to "kinematic".

    Hi, thanks for replaying. i tried running with kinematic but it didn't work. I attached my whole directory folder in my drive and link is below. Please take a look and help me to solve this problem.

    These are your communicators info during assembly opening

    WARNING: The following input communicators did not match with unique output communicators:
    baja_powertrain.cil_tire_force
    matched with: Front_tire_baja.col_tire_force
    also matches: Rear_tire_baja.col_tire_force
    baja_powertrain.cir_tire_force
    matched with: Front_tire_baja.cor_tire_force
    also matches: Rear_tire_baja.cor_tire_force
     
    I found that you have powertrain subsystem minor role any, it should by rear (your vehicle is rear driven),
    second thing, add brake subsystem
    third thing
     
    those communicators
    testrig.cil_toe_angle_rear
    testrig.cir_toe_angle_rear
    testrig.cil_camber_angle_rear
    testrig.cir_camber_angle_rear
     
    are needed to be connected
     
    fourth thing spring in front and rear subsystem are pointing to different database. I do not know why but i was not able to to change them to some existing spring property file from shared database. Program was mentioning about different variant, which is not there. I was able to change them only in text editor.
