Cadillac Battery Light ON & Message on DIC
Updated Friday Apr 06, 2018
Is your Cadillac battery light on? Are you getting "Battery not charging" on your DIC? These Cadillac problems including car not starting often happened because battery voltage is too low. The problem can be a bad alternator or old battery but it also a poor ground connection, voltage regulator, blown fuse, bad relay or even due to a parasitic draw. Cadillac electrical issues can be tricky and challenging to figure out.
The first step in troubleshooting Cadillac battery problems is to check battery voltage on the DIC by pressing the vehicle information button until Battery Voltage is displayed. Battery voltage should be in the 11.5 to 15.5 volt range. If the battery voltage is below this range, allow the battery to charge. If your Cadillac battery is old or not holding a charge you need to replace it.
If the message or battery light continues to stay on you will need to test the charging system including the battery and alternator. This test can be performed by your Cadillac dealer, auto mechanic or yourself if you have the right tool.
Below you will find instructions on how to test Cadillac battery and charging system yourself.

Battery Saver Active
If Battery Saver Active is displayed on the DIC it is because the voltage is dropping below the recommended level of 11.5 bolts. Your Cadillac will restrict power to certain features, power options and accessories to allow the battery to charge. You should turn off any unnecessary accessories as well such as rear defrost, phone and GPS chargers, lights if not needed.
Battery Volts Low
If the battery in your Cadillac is discharged significantly and voltage is below 10 volts a message will show on DIC stating BATTERY VOLTS LOW. In such cases, you will need to jump start your Cadillac. You will need to drive or let your Cadillac idle for at least 30 minutes or longer to charge the battery. Another option is to use a 12 Volt Battery Charger to bring your Cadillac battery back to fully charged status.
