No , he is wrong the ABS should not be on beyond the initial start up. That means you have no ABS, once it detects an error it illuminates the light and disables the function. The trucks go thru a self test every time and the computer will reset itself once there is no error. Does your truck have RWABS or 4WABS? The rear wheel only codes can be pulled by you, the 4 wheel ABS codes need a good scanner. The rear speed sensor is most common thing to fail but pull codes 1st.
