Door Module Wake-Up/Sleep States

The dash integration module (DIM), which is the power mode master, is responsible for sending a power mode message on the Serial Data Class 2 line to other systems. When the power mode message is sent, other systems respond to this message by entering a power-up state and sending a State of Health (SOH) code message. This SOH message indicates they are able to communicate information between other systems.

The door modules are able to control or perform all of the door functions in the wake-up state. The modules enter the sleep state when active control or monitoring of system functions has stopped, and the module has become idle. The door modules must detect certain wake-up inputs before entering the wake-up state and monitor these inputs during the sleep state. The door modules are able to detect switch transitions that cause the two wake-up states, activated or deactivated.
