Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello and thank you for using just answer!
The daytime running lamps on your vehicle are controlled by the body control ECU. Yes they can be turned on and off but the only way to do this is using the dealers multiplex body control system compatable scan tool in the "customized features" menu. This is not a feature that you can turn on and off by your self at any time, it can only be done on the scan tool.
