Configuration
The microcontroller configuration is defined during manufacturing through 4 zero Ohm resistors on the IHMI-
MPC board (cf. DOC02097).
Resistor

Too hot timeout 2 minutes 5 minutes 2 minutes
Reset button
Pressing the button reinitializes the power supply management microcontroller. The immediate effect is that
the system goes into power down state (state 1). Transition into another state depends on ignition signal
being on and temperature.
Note: the ignition signal state is taken into account 5 seconds after reset button is pressed.
