My DRL's are not working. I recently installed LED Switchbacks and they are working fine (as far as turn signals and parking lights goes). The only issue is no DRL's. I understand they should operate when the headlights are off, engine is running and emergency brake is off.
I am getting a B0502-RH DRL Relay Circuit and B0507-LH DRL Relay Circuit codes. I was getting the codes prior to the LED install. I just hoped they were bad bulbs, no such luck.
I am also getting a B2482-Backup Lamp Relay Circuit code since installing LED back up light. Backup lights are working fine even with the code.
