2004 Cadillac CTS 6 cyl Automatic

Hello,

I own a 2004 CTS and recently experience a problem as follows:
cruise won't work, temp & fuel guages won't work, anti theft indicator on continuoiusly, traction control indicator on continuoiusly, shifter position lights don't work, and key won't release after stopping motor.

Can anyone help?

thanks

Just the fuel gauge and temp is inoperative on the I/P, or is the tach and speedo as well? You could have a couple possibilities, a power supply problem, a communications problem, or even a faulty ECM. Try first disconnecting the battery cables and shorting them together. This removes power from all modules, and the shorting together discharges the capacitors. It can be considered a reboot. See if that corrects matters. If that makes no change, you are almost going to need a scan tool to see that you have all modules present, and can communicate with them. Was there perhaps a low voltage condition, or a jumpstart delivered to the vehicle prior to this?

Yes there has been a low voltage issue once
What should i do for that?

Check the charging system for proper output
See the guide below, it will help
