This unit describes the skills and knowledge required to diagnose and repair vehicle dynamic control systems. These systems include the functions of a vehicle electronic braking control module (EBCM), such as anti-lock braking, brake assist, descent control, electronic brake force distribution, electronic park brake, hill start assist, stability control, traction control and active roll-over protection. The systems used vary based on the work context. The unit involves preparing for the task, sourcing a diagnostic testing strategy, diagnosing the cause of the fault, carrying out the repair, performing post-repair testing, and completing workplace processes and documentation.
