Lock/Unlock Sequence

When the passenger front power door look switch is pressed, the following events occur:
1. The Passenger Front Door Module (PFDM) will directly sense actuation of the passenger door power lock switch.
2. The PFDM will send a Serial Data Class 2 message to the Rear Integration Module (RIM) requesting that the doors be locked.
3. The RIM receives the request message and examines for the following lockout prevention criteria:
^ IGNITION SWITCH KEY PRESENT from the ignition switch
^ DRIVER DOOR OPEN message from each of the door modules
4. The RIM broadcasts a serial data link command message to lock all of the doors when:
^ The ignition key is out of the ignition switch.
^ The driver's power door lock switch is held in the LOCK position for greater than 3 Seconds (Lockout Override).
5. Each door module receives the command message from the RIM.
6. All four modules actuate their door lock motors, thus completing the locking sequence.
