Causes for Low Battery Error Code from Blue Ox Patriot Braking System BLU37TR
Question:
Is there a internal battery in the unit? I keep getting error 4 low battery alert?

Expert Reply:
The Blue Ox Patiot supplemental braking system # BLU37TR and the original Patriot model BRK2012 do have internal batteries. Based on the error code you're seeing you have the original model according to my Blue Ox technical contact.
The 04 low battery alert code indicates that either the towed car's battery is depleted or that there is another issue such as a dirty 12V power outlet that is not passing enough power. The cigarette lighter outlet that powers the Patriot must output at least 13.1 volts for proper operation.
Check the condition of the vehicle battery to ensure it is fully charged; you can use an AC-power charger like # CTEK56353 to ensure the toad battery is fully charged before heading out.
