Chime
There is no actual "chime" for the backup warning. The chime is generated by the radio just like the "KEY IN IGNITION" or the "HEADLAMPS ON" chime. The Rear Parking Assist Moudle sends a signal to the BCM which requests the proper chime for the Radio to produce in the speaker(s).
Try turning the key to the on position then back to off 4 times, then press the driver's door lock button. You should hear a chime if it works.
Underneath the chrome trim above the license plate. Remove the 4 or 5 screws that hold the trim in place and the chime will be the round speaker attached next to the license plate light.
The warning chime is on the instrument cluster. It needs to be disassembled to get to, and it cannot be disabled because it is tied in to the instrument cluster.
