DRL's Stay On w/Engine Off
Searched the forums with no luck. I have a 2007 LS and the Daytime Running Lights (DRL) remain on after the engine is turned off. They remain on until the battery is dead. Tried to turn them off at the stalk with no effect. Bad relay? Bad switch? Ideas?

not entirely sure if the 'balts have relays for DRL, but the ion's don't. BCM controls the DRLs. i'm quite sure the BCM also controls the accessory delay and battery saver feature. perhaps you're in need of a reflash or replacement...

Thanks for the advice. I got the DRLs to go out after I disconnected then reconnected the battery. However, this is the second time they have remained on...first time lead to a dead battery at work. I'll try the relay approach as recommended and then move to the BCM.

Update: I think it's the low beams that are staying on, not DRLs. I pulled the DRL fuse from the engine compartment fuse box with no effect. I then pulled the fuses for the low beams (rt and left) and the lights went out. I pulled the fuse box out of the engine compartment (driver's side). The relays and fuses plug into a circuit (wafer) board. Volt/ohm meter was useless. Don't know where to go next.
