Mode $01 (Current Powertrain Diagnostic Data)
WARNING: This page is about a different car, the 2012 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.
Refer to data denoting the current operating condition of analog input/output, digital input/output or the powertrain system.
