Subaru impreza 2017 - ABS (Anti-Lock Brake System); ABS Self-Check; Disc Brake Pad Wear Warning Indicators

Two types of control models can be used. The two control models are "direct with
normal security" and "SBO (Select-Before-Operate) with enhanced security". The
parameter CtlModel defines which one of the two control models is used. The
control model "direct with normal security" does not require a select whereas, the
"SBO with enhanced security" command model requires a select before execution.
The command sequence for a command with control mode SBO with enhanced
security is shown in figure
127, with control mode direct with normal security is
shown in figure 128.
