Help!!!!!
 

My service engine light and security light are both on at the same time while im drivng does anyone have an idea of whats wrong ????

More info needed. could be many things.

Let me guess, bad battery ??? could be that or something electrical

Maybe try and pull the correct fuses and reset the computer and see if you can clear that out of there, just a suggestion.

JET

well i disconnected the battery and nothing happen the two lights still came on i went to AutoZone and they connected the little computer up and read it and it said nothing was wrong, i was thinking last night that the battery might be going dead

common gm failure for the security light is a failed pass-lock sensor, (lock cylder), ...just a guess, could be many things, but this will turn on both lights,
