Bonnet Ajar Indicator Description and Operation
Bonnet Ajar Indicator System Components
| • | Body control module (BCM) |
| • | Hybrid Powertrain Control Module 2 |
| • | Driver information centre |
| • | Bonnet ajar switch, part of the bonnet latch assembly |
Bonnet Ajar Operation - Body Control Module
The BCM applies B+ to the bonnet ajar signal circuit and monitors the voltage to determine the position of the bonnet. The bonnet ajar switch contains a multiplexed resistor. This resistor will vary the voltage seen by the BCM by pulling down the applied voltage based on the position of the switch.
Bonnet Ajar Operation - Hybrid Powertrain Control Module 2
The hybrid powertrain control module 2 applies B+ to the bonnet ajar signal circuit and monitors the voltage to determine the position of the bonnet. The bonnet ajar switch contains a multiplexed resistor. This resistor will vary the voltage seen by the hybrid powertrain control module 2 by pulling down the applied voltage based on the position of the switch.
