Condition:
Cause:
North America
Remote Keyless Entry inoperative, no crank/start, B3031 stored , possible Ready
For Fob "X" message on the DIC.
Intermittent door lock cylinder input sent to the BCM causing entry into manual
fob learn mode.
Correction:
If you have a vehicle that presents as a no crank, no start with the active and passive keyless entry inoperative , a
"Ready For Fob "X" message on the DIC and possibly a B3031 stored in the BCM, complete the fob learn for both
fobs using SPS.
Then monitor the Drivers Door Window Switch data in the BCM for a Door Lock Cylinder Switch input that
intermittently ashes "Active".
Cycling the drivers door lock cylinder 5 times in 10 seconds will put the BCM in manual fob learn mode.
This condition is likely caused by an anomaly in the drivers window switch sending an errant message to the BCM
via the LIN bus.
Suspect the drivers window switch as being the cause.
