Power Door Serial Data Link
The power door serial data link does not communicate with the scan tool via the
DLC. Power door serial data information is interpreted by the Driver Door Module
(DDM) and transmitted on the Class 2 data link by the DDM.
The power door serial data is used for serial data communication between the four door modules as well as the window switch driver.
Refer to Diagnostic System Check - Door Systems.
