Learned Features
The BCM has the ability to LEARN additional features in the vehicle, provided the appropriate switch input and PCI data bus messages are received.
Refer to the LEARNED FEATURES table.
When replacing a BCM there are three modules available:
-
Base
-
Midline
-
RG - Export
The Midline controller is used on vehicles that have Power Door Locks. If a vehicle is equipped with the Vehicle Theft Security System, the Midline
controller becomes a Premium when the theft feature is enabled.
CAUTION: Do not swap Body Control Modules between vehicles or body controller's off the shelf.
The BCM has internal diagnostic capability that assists in diagnosing the system error. When an OPEN or a SHORT circuit exists, the diagnostic tool
can be used to read the BCM faults. The faults are very descriptive in identifying the appropriate feature that has faulted.
The only two faults that the BCM logs that conclude the replacement of a BCM are faults;
-
# 01 - Internal BCM failure (replace BCM)
-
# 1F - J1850 Internal Hardware Failure (replace BCM)
Otherwise the appropriate diagnostic procedures for each of the features should be taken when the BCM logs a fault.
