If the daytime running light is not operated well, Inspect the connector and terminals to be sure they are all making good contact.
If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
If the terminals look OK, go to step 4.
Make these input tests at the connector by using ETM.
If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the I/P (Instrument panel) junction box must be faulty; replace it.
