Will this code cause problems with auto locks and transmission torque converter. How to replace ECU?

Asked by for the 1993 BMW 318is
Your voltage is too low. How's the battery? What's the belt look like? Check the battery with a multimeter and make sure the charging system is working. If you can't figure it out check with Adrian at Milt's. He's the BMW guy around here. (707)643-7548
