H-Bridge
•When output is off/disabled, the output is grounded.
When output is on/activated, the output is +12V.
Note: H-bridge are useful for driving motors in both directions, otherwise you never use this type of output.
For power hungry E-Throttles (like the BMW S54), it is recommended to paralell wire the outputs, see BMW S54.
Low driving (GND)
•When output is off(disabled, the output is not connected.
•When output is on/activated, the output is grounded.
High driving (+12V)
•When output is off/disabled, the output is not connected.
•When output is on/activated, the output is +12V.
Note: GPO 8 on all ECUs has a 660ohm pullup to either +5V or +12V (selectable in software)
Wiring a led to a GPO
Wiring a LED to a GPO can cause the LED to "always be a bit on" cause of the leak current, by adding a ~120ohm/3W resistor in parallel over the LED will solve the problem.
