USA car,? or not or Canada, sorry they are not all the same
DRL on the car? daylight running lights Y/N???
check all fuses first.
scan the PCm
check the DRL module for burnup's. seen many.
head lamps work key on and key off by law ,USA.
High and low beams dead that is 4 lamps.
car drives normal and no other electric failures??????
look for HL relays yet.

Hope this helps

first go for the easy stuff. do the tail lights come on? if so, then will almost guarantee it's bad bulbs in headlights. if tail lights do not come on I would check fuses first relay second. switch third.

Look in the owners manual. Most like under hood on top of fire wall fuse and high amp. Relays under cover.

The daytime running lamps in your 2001 Chevrolet Impala are controlled by the Body Control Module (BCM) Here is a description of how the system works:

The ambient light sensor is a light-sensitive transistor that varies its voltage signal to the Body Control Module (BCM) in response to changes in the outside (ambient) light level. When the BCM receives this signal, the BCM turns ON either the DRL or the headlamp relay for auto headlamp operation. Any function or condition that turns ON the headlamps will cancel the DRL operation.
Thirty seconds after you start the ignition with the headlamp switch set in the OFF position, the DRL will perform one of two actions:

Illuminate the high beam headlights at a reduced intensity in daylight conditions
Illuminate the low beam headlights in low light conditions
The DRL/EXT lamps fuse in the top of the engine fuse block supplies battery positive voltage to both the DRL switch contacts and to the DRL relay coil. When the BCM energizes the DRL relay coil, current flows through the right high beam lamp, to the left hand high beam lamp, to the energized DRL relay switch contacts, to ground G101.
The high beam headlamps are now in series, and split the voltage so that the headlamps illuminate at halt intensity. The DRL operates when the ignition switch is in the RUN position, and the parking brake is not set or the transmission is not in park. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate.

When the headlights go out, check for power to the low beams on the orange (RightT) and orange/black (left). If you're getting power, then the problem is on the switching/ground side of the circuit.

The body control module uses the ambient light sensor as an input and the headlight switch. If the light sensor see dark, the BCM provides ground to the control coil in the headlight relay. When the control coil is energized, it closes contacts that provide the ground path to the headlights. Since this is intermittent, I suggest tapping on the headlight relay with a screwdriver handle when the lights go out. It's located behind the glove box. Or, try swapping the relay with a different one and see if that solves the problem

It sounds like your DRL RELAY/Headlight relay. I had this happen with a 2000.

Please rate me if this helps You.

Here is some info that I hope is helpful to you.

This first part is how to disable the DRL
TOYOTA. From the Toyota technical service bulletin EL011-00 Web site for specific models determine where the module is; either the DRL relay or the body ECU, connector number, pin #. Oct 6,2000.

-disconnect battery- Then remove the wire with pin attached and tape to the harness. (consider just cut and tape the wire) -check operation- [except the 2000 MY-Avalon, additionally you need to ground the wire at the module end of the cut wire]


And here is the Headlamp relay part number.
