What exactly does this do?  I haven't had enough time to play with it and don't have an owners manual...so if someone has a quick answer I would appreciate it :)

When it's on, and you open the doors, the interior lights should not light up.  Good for sleeping kids.  I don't know if your '97 is like the mid 2000 and up trucks, but on them, you can press it 4 or 5 times, hear a chime, and then have manual control of the automatic headlights.  When you turn the truck off, the auto headlights reset back to auto mode.

Just as an aside for those of us North of the Border, GM Canada does not use the 4-5 push to override DRL feature.  Tried it on my Av2500, and it didn't work, so I consulted the owners manual, and low and behold, there in the fine print 'no go yo Canuck!!'

I guess that's because DRL's are mandatory up there?  Is that right?

Hey Tom

 

In order to pass Canadain Transport Regs, the DRL's have to be non-defeatable apparently.  Where the vehicle is made is not at issue, as the autopac has vehicles running across the borders all the time.  It is which country/area that the vehicles are sold into that they program for.

 

As a general rule, a vehicle built for US sale can not be sold new in Canada, and vice versa, unless it is inspected and certified to that countries standards.

My 2000 GMC Sierra was built in Canada, and I can press the dome button 3 times to turn off the day running lights.

I don't know about the made in Canada bit, but pressing the button 3 times still turns off the DRL's but it doesn't turn your interior dome lights back on.  The 4th time reactivates them.  I personally would find it irritating to not be able to override the lights.  It's nice to turn them off at Christmas light displays, fireworks displays and being courtious to the MPs and such at military bases.

Hey Guys

 

Yes, the 'one click on the parking brake' DRL disable is toast on Canadian trucks.  My dads 2001 Sierra, and my 2002 Av., both work as follows...

 

If started with Parking Brake on, no DRL

Release Parking Brake, DRL come on

Push Parking Brake, as many clicks as you like, DRL stay on.

To turn off DRL, set Parking Brake, turn off ingnition, and restart truck.  

 

No, I am not especially pleased with this either.  Frankly, another great example of a Canadian Beaurocrat re-inventing the wheel, and deciding square will work better than round.  Next trip south of the border, I may see if a US dealer can reprogram the body computer for me.  I doubt they will do it, but I am going to check.  Other option is one of the override switches.  Funny thing is, I can't disable the DRL's, but every RCMP unit (Federal Police Service) has a DRL disable switch (for obvious reasons).

 

Anyway, the news from North of the 49th

      OEM Trailer Hitch Receiver - Impact tightened by shop

      By SoCal Angler · Posted

      After my recent rear end bumper damage, body shop has made the repairs and included a new OEM receiver hitch.  I started thinking about how it was tightened...to specs or by hand or ??.  I called the body shop and asked and they said it was tightened by an impact gun.  I said I wanted it tightened to OEM specs.  They said no problem, bring it to shop today and they will torque to specs, which they say is 74 ft/lbs.   A couple of questions,,,,   1.  Should new bolts have been used?  If so, how many are there (bill shows one and four (I assume different areas of receiver).   2.,  Since they torqued with impact gun and now are going to probably loosen and then torque to spces, will that damage/stretch the bolts?   3.  If old bolts were reused (truck has 9000 miles), is that a problem?   4.  Any other things iI may have missed with regard to receiver replacement?   Thanks!

      Defective Brake Pad Wear Sensor?

      By newdude · Posted

      Is this supposed to be in English?  "close to 100 fake, new brake pads sign on the dash board"     Pull the wheels off.  Check the brake pad thickness.  Check the sensors out.  You could have good pads and the sensors aren't in to the worn out position, but have an electrical fault with the sensor or the plug wiring to the sensor.

      Tomorrow I go in for my third joint replacement in jus a little over a year year!  I am not worried about the surgery but I am a little annoyed about going through the recovery process again!  I keep my frustrations to myself as I do appreciate that I am truly lucky.  Knee, hip, and shoulder replacements are routine, safe and improve mobility.  The next couple of days will be slow but every day following will see steady improvement in my mobility.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Practical Application ISO 4406   I think this oil cleanliness thing is going to boil down to ones personal resolve. The information is there but applying it I believe will test your commitment to the machine. Implementation would involve building or buying a prefilter or purchase of an "ISOCLEAN" oil. Then installing a single digit micron bypass system. A good deal of testing and about 99.9% of you are saying at that point....yea.....not my cuppa tea. So what can you do?    You already did the first step. Get educated and leave the bias at the door. Be aware of the its, cleanliness, importance.    Do your own work if you can. Keep the equipment clean. Not just your funnel but the engine bay. Use sealed containers. Think it through.    I believe you will find, as I did, that the tightest absolute full flow filters (Beta 200) will be around 20 micron. That will yield on average a Beta 75 of 10-15 micron. They are few in number by brand and price point. Loose filters are a dime a dozen and even the best brands have lines of loose filters. Some cleverly marketed as "Extended Service". Others will market flow over efficiency. But I think the take away once informed is that the extra cost of the best offered is a bargain. There are cheaper filters with good efficiency that are equal in performance to niche brands with big prices. Your Quick Lube is about a 40 micron unit. This is where your dealer is a plus. the AC-Delco filter is a good step up from those places. Even better if you specify the UPF line.    Be skeptical of marketing. Buying an oil that is made from GTL advertised as the cleanest base oil is using a truth to support a lie. While GTL's are made from debris free gas the processing equipment and post handling is just like any other oil. It also ignores the fact that PAO's and Esters are also gas in origin. Any private prescreening testing you would do, and some have done, would yield a result only good for the batch you tested. AMSOIL and Schaeffer's have built a reputation for paying attention to this detail.    Context. Cold starts account for at least 75%, or more, of an engines wear. But of the remaining 25% ish, over 80% is caused by particle count. Now where do we find high milage motors that use this type of information efficiently? OTR trucking!      Now, anyone want to build a prefilter or off line cleaning system anyway?
