Bonnet switch
| Bonnet switch |
| General |
The bonnet switch is placed on the rear left of the engine bay and acts as a sensor for the bonnet. The switch is connected to pin 41 on the TWICE control module.
| Function |
A pulse width-modulated (approx. 3.5%) voltage is supplied continuously from the control module via a 1 kohm pull-up in TWICE to the switch. From this voltage, the control module can detect whether the bonnet is opened when the alarm is armed by testing the voltage at the input concerned.
