If DRL indicator light is off, check for battery voltage at specified DRL controller terminals. With coupler connected to DRL controller check White/Red, Violet/Green, Brown/Yellow and Black/White terminals. If all terminals have battery voltage and DRL controller ground does not have voltage, replace DRL controller.
For each wire terminal that does not have battery voltage, check circuit and related parts. Make repairs and replace parts as necessary.
