head lights

Your lights are controlled by the computor????

You'd be surprized what all is module controlled. Have somebody sit in your hotrod and press the brake pedal while you stand behind to watch the lights. Notice which brake light comes on first....

I'd guess the third. but the hi low beam? Thought that was a function of the switch.

Roy

The switch is an input to the bcm which sends the signal to the fcm which runs each individual lamp. With the starscan, you can look at each individual lamp to see if it's on.

Denny

Okay, so now what does he do with the flasher that shuts off early?

Roy

Is this only on the newer models? My 99 1500 switch was overheating (could smell it) when I tried to wire in 4 headlights. I had put a newer style fron assembly with 4 bulbs dremeled out to have hi/low beams installed in all 4 holes.

Never mind. The trailer had 2 lights on each side. Eliminated one per side and all is fine.

See ya can learn every day. But learning from the Rabbit........

Thanks pal.

Roy

Yes - all references to computer-controlled lights apply to 3rd Gen trucks ('02+ 1500's, '03+ 2500/3500's)

Well, don't thank too much cause I didn't have alot of luck finding anything today. Could find nothing in techconnect about reprogramming for the higher load. Didn't have a chance to hook the scanner to a magnum to see if I could find anything to flip. Did ask a few of the guys to see if they had ever ran into this and one of them thought an extra module had to be connected to the trailer wiring at the connector. This module came from the local U-Haul outlet and was for this particular problem. He couldn't say much else about it tho.

So how's that for playing stupid?????? Really not much playing about it... There, I beat ya to it...

Denny

I'd say it was better than the average "dumbguy"

sorry fellas, with recent plays on names i couldn't pass that one up.
