Can you guys with 2nd gens perform this test for me? I think I have something wrong but I'm not sure.
Park truck in very quiet area
turn it off. Turn lights off, everything.
turn key to ON position, but don't start truck
wait for seatbelt chime to go away.
listen in the engine compartment
do you hear any sound? Mine is making an electronic hum, about as loud as a computer fan, but sounds like a microwave in use. If I press the brakes, the front continues to hum, plus I get a louder hum from the rear.
I'm wondering if ABS is tweakin out even though everything operates normally
