“Wait to start? I just turn the key until it starts.” This is the biggest piece of the puzzle for me. The next answer I hear is usually the same and I believe is part of the cause of the B2960 code. If the customer says the light was flashing after the no start or they say they didn’t notice the light, I will continue to proceed in this direction. If the customer says the security light came on while driving and the no start happened later, then my diagnoses will go a different direction. I will call the customer and ask them a few important questions when did you see the security light and do you turn the key to on before you start your vehicle. My next step is the most important once you get this far. Next I will check power and ground connections. First thing I will do is test the battery electronically with my midtronics tester and then load test it.
#Gm key codes code#
What I do next if there are no other codes that I think relate to the no start, the key code voltage is correct, no other security data pid problems, and after clearing the code it does not reset and the vehicle starts. I will check the key code voltage and see if it matches what it wants to see. I will see if there are any other codes in any of the other modules. When I get the code B2960, I will look through the security data pids for any problem. The information I give from here is from what I have seen and is my opinion for some of the problems that cause this code. I also get a U1000 code a lot with this code which may be related, may not be. So you then go and scan the vehicle and you get the code B2960 (key code incorrect but valid). Well we know many things will do this like the fuel pump, ignition components, starter, etc. I am sure many of you have had a GM towed in as a no start and when you go out to try to start it, it fires right up.
