Chevy's Dead Bluetooth + Error Code: Quick Fix Guide

Had the same problem on my 2013 Chevy Cruze diesel last month. The Bluetooth connectivity issue wasn't just a simple pairing problem, it turned out the main control module in the ignition system was failing. When they scanned it, multiple electrical faults showed up related to the car's communication network. The issue needed immediate attention because these electrical problems can spread to other systems. In my case, it was already affecting the engine light and fuel system monitoring. The control module replacement was necessary, not something you can postpone since it can lead to more serious electrical issues down the line. Quick tip: Before heading to a shop, try disconnecting your car battery for 10 minutes. This sometimes resets the system and fixes minor electrical glitches. If that doesn't work, you're looking at professional diagnostic work. Just make sure to find a shop that specializes in automotive electrical systems rather than a general mechanic.

Thanks for sharing your experience with the control module issue. I had a similar problem with my Enjoy last year, definitely sounds like we're dealing with the same electrical faults. The transmission and drivetrain warning lights started popping up shortly after my Bluetooth died too. Quick question, do you remember roughly what you paid for the module replacement? I got quoted a pretty high number but wondering if it's in line with what others paid. Also, has everything been working smoothly since the fix, or have you noticed any other electrical gremlins popping up? I tried that battery disconnect trick last night but no luck. Think I'll need to bite the bullet and get it checked out properly before it spreads to other systems.

Just wanted to follow up, got my Enjoy back from the shop and it was way simpler than my previous control module problem. Turned out the Function restrictions error was just due to an incorrect pairing with the end device. Total bill came to 45€ for the fix, which was a huge relief after expecting something much worse. The diagnostic showed no deeper electrical faults this time, unlike my previous experience. All the warning lights are gone and the Bluetooth is working perfectly now. The steering and drivetrain warning messages that were popping up have completely disappeared too. Much better outcome than my last repair when I needed that full module replacement. Sometimes these electrical issues look scary but turn out to be pretty straightforward. If anyone else runs into similar symptoms, might be worth checking the basic pairing setup before assuming the worst.

Thanks everyone for the input. Finally got this sorted out and wanted to share how it went down. Took the car to a new mechanic who specializes in automotive electrical systems. The guy actually spent time diagnosing the issue instead of just throwing parts at it. Turns out it was a damaged wiring harness causing intermittent electrical faults in the entertainment system. The mechanic found some corroded pins in the main connector, guess that's what was messing with the Bluetooth and triggering those unusual warnings. Total repair included cleaning the connections and replacing a small section of the harness. Bill came to around €200 including diagnostic time, way less than I was quoted for a full module replacement. Been about a week now, and everything's working perfectly, no warning lights, steering system's good, and the Bluetooth's connecting like new. Definitely learned my lesson about finding the right specialist for electrical issues rather than going to a general repair shop. The proper diagnosis made all the difference.
