CCM Interface W/Passive Keyless Entry (PKE)

CCM Interface with Passive Keyless Entry (PKE)
The Passive Keyless Entry (PKE) module interacts with the UTD system (part of the CCM's operation) in the following ways:
^ PKE sends "Arm UTD" and "Disarm UTD" signals to the CCM.
^ Upon receiving a "Disarm UTD" signal from PKE, the CCM turns courtesy lamps "ON."
^ Upon receiving an "Arm UTD" signal from PKE, the CCM turns courtesy lamps "OFF," and momentarily sounds the horn to indicate security system arming.

The CCM-based UTD system interacts with PKE in the following ways:
^ CCM provides UTD status information to PKE.
^ CCM provides key-in-ignition switch status to PKE.
^ CCM sends a programming request signal to PKE when the appropriate DIC button-pressing sequence has been completed.
