Can anyone help me with the security light codes on the dash? It flashes 1 then 6. I assume this is code 16?
I had a crank with no start condition when I was putting the car away for the winter about 2 months ago. Didn’t get to mess with it until just now. I was going to start with troubleshooting the fuel pump but I noticed the security light was flashing while trying to start the car. When I went down today to try it again, it started and ran normally. That’s when I counted the 16 code. Finally after running for a few minutes the code cleared, light stopped flashing. Could this be related to my no start or just coincidence? I’m not very familiar with the car as my wife drives it way more than I do, so I don’t know if the light usually flashes?
Any help is appreciated.

If a problem occurs with the Passive Anti-Theft System (PATS), the indicator will flash rapidly or glow steadily when the ignition is in the RUN position. If this occurs you should check for faults in all of the control modules. If the problem is with the PATS, a fault code will be stored in the instrument cluster.

Thanks Doug. I assume this will be read through the OBD II?
Kinda makes sense if what I saw 1 6 may relate to 1600, that may give a crank with no start. Maybe I’m overthinking it. lol
 
The stored codes from the different control modules are accessed through the OBD Data Link Connector using the proper scan tool. Biddle suggests using the Blue Driver scan tool which pulls the most codes and provides suggested fixes.

Big Blue Driver fan and have 3 of them. It collects the DTCs and then pings a cloud database for causes of the fault for a SPECIFIC make/model and offers up solutions that have been used to correct it.
