I've tried doing a search on this topic but come up empty.

I'm getting a little tired of the lights popping up when it is still light out. How do I go about disarming this feature?

I don't know if it makes a difference but this is a Canadian vehicle.

Tried that already, doesn't work. Must be the Canadian cars having a lockout with the DIC.

Any other suggestions. :crazy:

Ragtop--Sounds like you have the Canook option. The tech has to disable it at the BCM. I have the same option and that's how its done. Its easy and it only takes a few minutes. :thumbs:

Actually, you can do it yourself. It took me about 7 minutes and $1.

Following information obtained on the forum, I did it as follows:

1. I used a CREDIT CARD to 'work'/loosen and 'pop out' the dash top defroster grill..

2. The Twilight Sentinel (TS) sensor itself comes in a base/housing that plugs into a female socket on the left hand underside of the defroster grill. It simply screws into its defroster grill socket, requiring only a 1/4 clockwise turn to 'lock' it into place like (eg.) a tail light bulb into its socket.

3. Before I did ANYTHING (even unscrewed the sensor from the grill), I tied some *black* fishing line (about 4 feet worth) around the ACTUAL WIRE connecting the sensor to the harness, ***JUST IN CASE the whole thing should accidentally slip down into the dash during the process***, so I could pull it up again... (THAT WOULD BE A PAIN - the head lights would then ALWAYS be on when the car was running, and trying to fish it out again looked like it would NOT be easy...).

4. I THEN unscrewed the sensor from the defroster grill.

5. THEN, the sensor itself simply plugs into a male connector on the end of the wiring harness lead, so I unplugged the sensor from its harness connector. (I used a small jeweller's screwdriver to release a clip to allow the parts to be separated).

6. I then reinstalled the (now disconnected) sensor back into the defroster grill (for 'looks' only, since it's now non-functional),

7. Next, I bent the leads on a 4.7K OHM ½ Watt resistor that I picked up today (6-pak for $1.49; needed only one), and plugged the resistor leads into the contacts on the end of the male wiring harness connector. (Real nice fit - tight but not too tight).

8. I then taped the resistor/connector up to prevent shorts and provide further insurance against them coming apart, using black electrical tape.

9. I then ***taped the connector to the sensor housing*** , the objective being to help ensure that it wouldn't flop around/rattle/make noise if simply left loose.

10. I then looped and tied the fishing line through a couple of bars in the defroster grill, leaving only about 4" of slack to its tie point back on the wiring harness, and cut off the surplus line with scissors - JUST IN CASE THE ELECTRICAL TAPE SHOULD EVER SOFTEN/COME LOOSE FROM HEAT IN THE CAR and the resistor/lead might decide to separate from the sensor and drop down into the dash as mentioned above and cause noise/be difficult to retrieve...

11. I then reinstalled the defroster grill and 'voila'.

Thanks Racer44,

Tired of having my lights acting like speed brakes when I'm dragging in the late evenings..... :mad

MYRagtop

Thanks guys. Just needed to gain control over those darn lights. :thumbs:

Should have it done later today.

With the Tech2 you can turn off the twilight RPO and permanently disable it!

Racer

Yes, but not all of us have access to tech2. :nonod: :cheers:

What do you mean by tech? Service ttech at the dealer? I also see people mention tech 2 and wonder what that is? I'm new and want to disable my twilight sentinal. My vette is originally from Canada.

The TECH II is GMs all in one interface computer and the only thing that can interface with the Body Control Module.

I removed the relay for that option in the passenger side fusebox, works great!

pjensen1954

Which relay are you refering to? Do you mean a fuse?, is so which one? Thanks you may save me a huindred dollars. The dealer wants a hundred to reprogram it.

sk7

Relay #44. No codes or issues whatsoever after removal.

pjensen1954

I did it this morning, and your right. The only issue i see is the lights won't shut off if I forget and leave them on, but they probably wouldn't anyways with the sentinal if I had the switch on. I ordered gadetmans relay yesterday before I knew about relay 44. I called few Chevy dealers here in the Detroit area about reprogramming , but none new anything about it. One dealer by my house said they don't work on vettes as old as mine
(2001) they're kidding right? 9 years old is too old? I'll do most of my own simple wrenching, but will find someone through a club or something that can refer me.

Zombie thread resurrection:
My 98 coupe apparently has the twilight sentinel but there is not an option for it on the DIC. It doesn't appear to be a Canadian car (all gauges are Imperial units). I'll try the stuff from this thread to get around it, but can anyone say why the car doesn't know it has the feature?
