You can also run BCM diagnostic codes without a scanner by turning your key ON
Then OFF
Remove your radio fuse
Turn your key back to Accessories for 5 seconds and your BCM will beep
"The Beep is the same noise you hear when your lights are left on, Key is left in the ignition ect.. that sound comes out of your BCM."
After you hear it beep Turn the Key OFF
Then Immediately back to Accessories
The BCM will beep again followed by the Security Light on your Cluster
will start flashing the codes.
1 flash pause 2 flashes that is a code 12 which = BCM Diagnostic System Check
It will do that 3 times then it will start flashing out the BCM Trouble codes..
