Data Monitor/Active Test

WARNING: This page is about a different car, the 2018 Subaru BRZ. However, it is still accessible from the selected car via links, so may be relevant.
  1. Data monitor
    CAUTION: In the following table, the value listed in the normal condition is a reference value. Do not depend on reference value only when judging if the part is faulty.
    NOTE: By using the SSM4 and reading [Data monitor], you can read the statuses and values for switches, sensors, actuators, and other items without removing parts. Because the non-intrusive inspection allows you to read the intermittent statuses or signals without interfering with parts or lines, it is very convenient. Diagnostic time can be saved by reading the [Data monitor] information at the initial stage of the troubleshooting.
    1. Connect the SSM4 to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn on the SSM4.
    4. Enter the following menus: [Keyless Access(Collation ECM)] →[Data monitor], or [Body Control] →[Data monitor], or [Brake Control System] →[Data monitor]
    5. Based on the contents of the SSM4 display, read the [Data monitor].
