How to disable daytime running lights and not throw error codes?
I pulled fuse #2 to disable daytime running lights, but every 160miles or so it throws error code 0507/0502 (no driver/passenger dtrl). Reset, and 160 later the code comes back and the check engine light lights up again.
is there any way to disable dtrl without getting those 2 error codes thrown all the time an dhaving the check engine light keep coming on?

Why would you want to not have the running lights?
Anyway, just remove the light bulbs. Keep the fuse in the fuse box where it belongs.

Here is how to disable them permanently and it is reversible and does not affect the operation of any other lights.
1. In the passenger foot well, lower the front carpet.
2. Remove the foot panel.
3. Locate the IPEC (Instrument Panel Electrical Center) it looks like the fuse box next to the battery.
4. Remove the cover of the IPEC.
5. Turn it over and find the diagram of the components.
6. Locate relays 38 and 40. (38 controls the right DRL and 40 the left)
7. Pull each relay and carefully remove the cover.
8. Insert some type of insulator between the relay contacts (matchbook cover cardboard or the plastic from a coffee can lid works well) that you have cut to fit.
9. Replace relay cover, replace relay, replace IPEC cover, and replace the foot well.
10. DONE!!

Btw, stupid question time - I don't want to do the jumper (I don't have anything small enough in my electrical toolkit to do it with atm) and I can tell if I remove the cover from the relay I'm going to snap the stupid plastic clips (or worse ) ..... can I just cover the area in the panel with electrical tape and call it a day? I assume so since the alternative text directions (that you posted) say to just insulate the relay contacts inside the relay ........ so it should make no difference if I stick the relay back in witht he contacts insulted inside the cover, or if I just cover it with electrical tape, no?

annnd the answer is you can't do that - with no relay in, the turn signals don't function, so the dtrl relays obviously control more than just the dtrl.
hence the jumper mod .... but I can't understand how insulating the relay contacts is any different than not having the relay in place.....

No jumpers involved, just cuttint the flow off to that circuit.
Cheao way around, pull your parking brake up one notch and they'll go off, only issue will be brake light on dash.

But I don't understand how opening up and insulating the relay contacts is any different than just not having the relay in there. WIth no relay in, my front turn signals don't work, and my rear ones flash at hyper speed.

because there are four legs on the relay and you're only disabling one set not both.

Pull the e-brake 1 click up. I just have the fuse pulled but I could care less about a code.

And yellow DRL are illegal in UK thats why mine is pulled + my side repeaters are constantly on if it isnt pulled. But the e-brake pulled up 1 click works also. I wouldnt not recommend the jumper. There is a reason why there is a fuse in there and you can fry your relay box or cause an electrical fire if a short occurs.

Not sure anyone actually answered your first question
The answer is that with any of the DRL mods you will still get the DIC codes because you've disabled the DRL circuit and the car is telling you that.
I did the jumper mod and I still get them.
As explained, the jumper mod protects the turn signal circuit but inhibits the DRL circuit by hard wiring the circuit in lieu of the relay.

Hoho, 2hrs later and I finished it - I didn't have any prongs of the proper size, so I used some of my oversized ones and slowly ground/test-fit/ground it until it fit in nice and snug
ooooo, I hope I don't get any problems with the no #2 fuse + no 38/40 relay + jumper mod ...... I don't care if the DIC quietly stores the code, but my problem is that every 150miles or so the bloody 'check engine light' pops up (dtrl code) and I'm getting tired of re-setting it.

There's no need to. Pulling the fuse effectively opens that circuit. If that circuit some how miraculously received a short, in lieu of having the fuse removed, nothing short of disconnecting the battery would help.

Great option if you do.

Ummm,....... "Tork Stik" asked that question over 3 YEARS ago.
