18010/P1602/005634 - Power Supply B+ Terminal 30: Voltage too Low
Possible Causes
* Cables on the Battery were removed
* Battery weak (voltage)
* Generator Disfunction
Possible Solutions
* Check Battery Cables
* Check/Replace Battery
* Check/Replace Generator
Special Notes
* If multiple Control Module have Power Supply Faults stored, it's most likely to be one common Problem like the ones shown above. Otherwise when only one or two Control Modules have such Codes stored you better start searching at the individual Power Supply of these Modules.
