it's not the bcm it's the drl resistor very common problem.here is a bulletin
Daytime Running Lamps (DRL) Inoperative (Inspect/Replace DRL Resistor)
2005-2006 Chevrolet Equinox
2006 Pontiac Torrent
2002-2007 Saturn VUE
[/align]Some customers may comment that the daytime running lamps (DRL) are inoperative
The DRL resistor may be cracked and corroded.
Inspect the DRL resistor to determine if the resistor is damaged using the procedure below:
[ol]Verify the condition.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in SI.
For Chevrolet and Pontiac, loosen the left front corner of the inner wheel liner to front fascia. Refer to Front Wheelhouse Liner Replacement in SI.
Visually inspect the daytime running lamps resistor located on the left front frame rail for cracks and corrosion.
If the resistor is cracked or corroded, replace the resistor. Refer to Daytime Running Lamps (DRL) Resistor Replacement in SI.
If the resistor appears to be good, Do Not
proceed to the next step. Refer to Daytime Running Lamps (DRL) Inoperative in SI.
Assemble the new DRL resistor with the new washer and bolt as shown in the graphic above.
Install the DRL resistor to the frame rail.
Tighten the new DRL resistor bolt.
Tighten the bolt to 6N·m (53lbin).
Connect the DRL electrical connector to the DRL Resistor.
For Chevrolet and Pontiac, install the left front inner wheel liner. Refer to Front Wheelhouse Liner Replacement in SI.
Verify the operation of the daytime running lamps. might want to check this first.[/ol]
