Couple of questions:

1. Now, the stereo is asking for the 4 digit code. Since I bought the car used and the previous owner never gave me this info, how can I obtain the 4 digit code for the stereo?

2. The car needs to do a California Smog Check soon, do I need to do a drive cycle before the smog check? If so, where I can find the details of the drive cycle?

Thanks

I recently disconnected my battery prior to my Cali reg renewal. After re connect I checked the readiness monitors with a code reader and my durametric, everything remained ready. You can have Autozone or Oreillys check their status or for ~$50.00 buy a code reader they are nice to have.


This works fine. https://www.autozone.com/test-scan-and-specialty-tools/code-reader/innova-obd2-tool-with-emission-readiness-monitors/273349_0_0
