Yep, the code 000602 “Closed-circuit current above limit (eEm)” is basically saying:
The car is detecting too much electrical draw while it should be asleep. So, look for a glove box light on, or it can be the AC compressor relay is stuck on as well which is common. Also, does this car have a CD player I would check to make sure a CD is not stuck causing the eject motor to run. I have also seen a weak battery cause this as well. Can I ask how old the battery is? If it is more than 5 years I would replace it. Please go over this guide which can help us find the problem.
