I would like to disable the DRL for my 1999 Tracker which I think is very close in design to the Vitara.
I want to upgrade my headlight bulbs to the Sylvania Silverstar and do not want the DRL using up my lamp lifetime, instead I would rather disable the DRL or switch them onto an alternative light source as a secondary fog or driving light.
OK - I think I understand now what you're looking to do.
Let's start with the headlights - what I have access to is the Suzuki manuals, not the Tracker ones, so there may be differences.
First step is to determine what "light control" options you have, there were two different options available on the 1999GV - DRLs and 'autolights' and we need to know which you have.
DRLs as I mentioned before run the headlights at partial brightness during the daytime - engine must be running, and I believe the vehicle in gear with the handbrake down. You should be able to start the vehicle and leave it in park with the handbrake up and have the head lamps stay off.
Autolights turn the lights on automatically when the vehicle is in the dark and the engine running - based on an ambient light sensor on the dashboard.
Does your car have both of these options or only the DRL?
What happens if you unplug the "DRL" controller - do the lights go off, not come on or what? Sure I understand "it doesn't work for me" - but exactly what happened?
I thought my Vehicle only has DRL's, no autolights. Just went out and checked - in enclosed carport with engine running the lights are on with and without the handbrake on. Out of the carport with the engine running the lights go out when handbrake is on. So now I think I must have autolights.
Unplugged the DRL Module and everything stayed the same, but i had not turned of and then on again the engine...will have to check that part out more.
Working on a headlamp wiring harness right now before dark sets in so I will run back and forth from time to time to check the thread.
I have the Tracker service manuals for about a week and there are a ton of pages but everything is here if you need a pic.
I still want to check if the DRL control module dis-connect works, like your thread says.
I do want DRL's but not with the headlamps...with secondary driving lamps would be ideal.
If I could power the driving lamps through a relay from the parking brake as my main power so that they would come on and off through the DRL module, but how to get it to not goto the headlamps is the thing. Does this make sense?
That link has most of its images pulled. That and the discussion within the thread seems to point out different model / year systems are (for the most part) all different with regard to component and wiring colors. It's confusing to me at least. Although I have no first hand knowledge of the subject and I have no desire to disconnect my DRL's, I thought I'd throw that out.
Also want to adjust the sensitivity on the auto-lights
(less sensitivity - they come on when it is before twilight when it is overcast)
That's up to you, but personally I think that's a bit over ambitious and a lot of needless effort. It works well as designed. If you don't like the function I'd eliminate it before I'd play with adjusting it. There are many variables (rain, clouds, shadows, obstructions) to try and achieve what you desire IMO. Just a thought.
For the ambient light sensor I have taken it apart and it seems that if you put the casing upto the light it will shine through but only if good amount of daylight is out, no clouds, rain etc., so I am going to drill a 1/8th inch hole in the casing at the top and seal it.( first i'll try scotch tape, then maybe glue from a gluegun to let in a bit more light)
I don't know how I should measure the difference so as to get back to you all but each person has their own level of comfort.
here's a pic of the ambient light sensor (ie: auto-lights sensor).
Also a link to a Tracker site referencing that - CanadianDriver Chevrolet Used Vehicle Review: Chevrolet Tracker, 1999-2002
"The ‘99 model was a major step forward in terms of styling, comfort, road manners and performance. I should also point out that the same can be said of the Suzuki Vitara and the V6-powered Grand Vitara. Not only do they share the Tracker’s mechanical pieces, they’re also built on the same assembly line in Ingersoll, Ontario."
