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 fea-
ture that has faulted.
The only two faults that the BCM logs that con-
clude the replacement of a BCM are faults;
• # 06 - Internal BCM failure (replace BCM)
• # 31 - 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. Refer to the proper Body Diagnos-
tic Procedures manual.

enabled by performing the following:
(1) Insert the key into the ignition cylinder.
(2) Cycle the ignition key from OFF to ACC four
times without going to the RUN position.
(3) Leave the switch in the OFF position after the
fourth cycle. This puts the BCM into the LEARN
