2019 Chevy Cruz used radio
Another shop installed a used radio. Worked for 30 seconds then stopped and says it’s locked.
We haven’t looked at it yet. We already told the customer it Probably cannot be fixed. Just wanted to do our due diligence and see if it’s possible to write the vehicle VIN into a used radio for this? Before we waste the money and time in trying.
Thanks in advance.
I did a 2017 the other day. Warned the customer it probably wouldn’t work but lo and behold it did.
Is it setting vin mismatch codes or environmental identification codes?
not 100% sure yet. Sounds like we just need to get out there and try ourselves.
Most GM vehicles from 2013 and above tend to be globa a archtype, basically vin locked. I haven't had any luck programming them thru conventional means (techline, sps). If you can find the eeprom for the original radio you might be able to swap it fromt the original to the new one (used radio) and that would transfer the vin but its a hassle and no one pays for the time it takes.
The short answer is no you cannot program them with sps or mdi if vin is in the radio. I can clear the VIN on most silver box tuners on my test bench but GM in Their infinite stupidity took the ability out to clear VIN on the global a radios.
I have cleared the vin on “global a” radios before via obd
Thanks everyone. I love being apart of a huge network of technicians. I’m going to inform her its locked and needs a new radio.
This will take two vin slots, Program the radio with the vin for the donor radio, this will unlock it. Ignore all the warnings. Then program the radio with the vehicle vin. This worked on the last global A vehicle I did, I think it was a 13 or a 14 regal. Hope this helps.
John, That is a pretty cool trick. Now I want to try it and see what happens.
John, for this to work you manually identified the vehicle with the VIN from the used radio? And then running a programming event didnt corrupt any other modules? (That is a question i am inquisitive about ) And then to program again with the correct VIN…. it will allow you to program again with current level software?
Yes, it did not corrupt the other modules. This was on a 2013 or 14 Buick Regal, SPS2 will warn you it is the wrong vin, just keep going. I don't know if this will work on a 2019 or not, I haven't tried on anything that new. That type of work always carries risks. I can't take credit for this, I got the information from Patrick Masters on one of the Facebook groups I am on.
I've had good luck tapping into the eeprom with a test clip and clearing it via chip editor on a pc. I just have the radio pulled and take it with me, though I could do it on site if needed. Takes around 45 minutes total. This is also me assuming this is a myLink setup. If you clear the eeprom, it will pull necessary info from the vehicle on startup and work like a charm.
