Operation CHARM: Car repair manuals for everyone.

Door Lock Actuators

The CTD system uses the door lock actuators as one method to activate the alarm. The driver door module monitors all door lock actuators via a discrete input or the Simple Bus Interface (SBI) from the other three door modules. If the RIM receives a class 2 message from the driver door module that a door is open and the CTD system is armed, RIM activates the alarm.
