UPDATE: The problem was that my dashcam memory card had failed and it was my dashcam telling me that I needed to fix it. Took me quite a while to figure out it was the dashcam because 1) I mounted the dashcam on the other side of my rearview mirror where I didn't have direct line of sight or I would have seen that the dashcam screen was flashing an error message, and 2) the beep sounded like it was coming from behind the radio, not high up on the windshield. SMH 🤦♂️
Problem solved.
****************************************************************************************************
Here's what I've got:
2014 Chevy Silverado 2500HD LTZ Durmax w/133,000 miles
Aftermarket Kenwood Excelon DDX6906S entertainment system
iDatalink Maestro RR Interface Module (for radio)
iDatalink HRN-RR-GM2 Interface Harness (connection harness)
BullyDog GT Diesel Tuner plugged into ODBII port (to use gauges)
No warning/error lights on instrument cluster
No airbag system warnings/errors
No DTC (diagnostic trouble codes - used Launch 431 Pro scanner)
No chime control module
Every time I start up my pickup when it hasn't run in more than 10 or 15 minutes, 5 beeps mysteriously sound off. These beeps do not seem to correlate to anything I can find at the momemt (they happen whether or not my seatbelt is fastened).
When I first noticed the beeps, I had a "Change Engine Oil Soon" message on the DIC, but that's it. I thought that might be causing the problem (although it has never beeped in the past when I needed to change the oil), but that wasn't it.
The beeps are not of the same tone as the door open, "fasten seatbelt," or "keys in ignition" chimes.
The beeps sound like they're coming from under the dash somewhere but I'm not 100% positve. I do know they're NOT coming from the chime speaker attached to the aftermarket radio.
Nothing in the owner's manual about it.
Can't find anything that makes sense from internet and forum searches.
I'm at a loss.
Any ideas?
