Scan Tool Output Controls
| Output Control | Description |
|---|---|
| Control Module Self-Test | Initializes the self test procedure. Unlocks the control module so certain latched DTCs may be cleared. |
| Discharge Energy Storage Capacitor | Initializes capacitor discharge to prepare module for removal. |
| Energy Storage Capacitor Learn | Only to be used if B101D 00 is set. This initializes the capacitance reset. |
