S10Wildside Posted October 10, 2003 Report Share Posted October 10, 2003 Let the electrical troubles begin! This morning I pulled my SS out of the garage, turned it off, got out, locked with the remote, closed up the garage, pushed the unlock button on remote, and the entry assist lights on the side mirrors did not come on. I tried playing with the lock/unlock button on the remote, but they still would not come on. It was very dark outside, so the lights should have come on. After I got to work (still dark), I pressed the unlock button on the remote and the lights DID come on. It's obviously not a fuse...so what's going on? I was hoping the electrical gremlins wouldn't show up until after a few years and after I sell the truck (who knows, it could happen). Link to comment Share on other sites More sharing options...

S10Wildside Posted October 10, 2003 Author Report Share Posted October 10, 2003 This is the only time I noticed that the lights did not come on. As a side note... I think I'm going to order the 2003 CD set from Helm. I hear there are a lot of modules in our trucks now and that one wire no longer necessarily serves just one purpose. Sounds like we've got data streams running all over the place. The CD set covers many newer GM vehicles, including the 2000 S-10 Blazer, 2000 Firehawk, and 2003 SS in the family. I guess that would be a good investment considering I do all the work on my vehicles. The CD set is $300 and the part number is GMPT02CDSI16. Now I'm kicking myself for ordering the 2000 Camaro/Firebird manuals for $120. Wish I would have known about the CD set sooner. Link to comment Share on other sites More sharing options...

S10Wildside Posted October 10, 2003 Author Report Share Posted October 10, 2003 Have you reset your computer yet for daylight savings?? Oh crap! I'll have to do that when I get home. I'll let you know how it works. Link to comment Share on other sites More sharing options...

S10Wildside Posted October 10, 2003 Author Report Share Posted October 10, 2003 Where does it say that I need to do that? What does that have to do with the problem? What he's saying is that the computer is out of whack because it thinks it's in a different timezone because of daylight savings. However, we don't set the clocks back an hour until later this month. I suppose GM could program the BCM to only activate the assist lights at a certain time of day, in which case timezone would matter. However, that's just plain silly and he's only joking with us. I just went along with it for kicks. But seriously, I'd like to know how those lights are wired in. Must receive a signal from a module (BCM maybe). Don't know why they didn't turn on. Guess I'll have to get the service manual to know how it all works. Link to comment Share on other sites More sharing options...
BenKey Posted October 10, 2003 Report Share Posted October 10, 2003 I would try turning the feature off, then turning back on, with a crank in between, or resetting the PCM. It's just a computer and we all know that they have quirks. My desktop at home has it's moments also. The precedure for resetting PCM, straight out of the huge manuals that slimsoftball purchased is: -disconnect neg batt terminal -turn ignition sw to start and hold for 15-20 secs -release sw and turn back to off -reconnect batt terminal This is quite a bit different than other procedures I have seen. He helped me fix a problem I had. I would try doing it if nothing else seems to work. Link to comment Share on other sites More sharing options...
Krambo Posted October 10, 2003 Report Share Posted October 10, 2003 Do those lights work when the dome light over ride button is engaged? Never tried it but sounds like a viable answer..... Link to comment Share on other sites More sharing options...

03_SILVERADO_SS. Posted November 1, 2004 Report Share Posted November 1, 2004 I believe the light sensor tells the bcm if the lights should come on, I noticed that if it's light out, my backup lights and drl's do not come on when the doors are unlocked. Just a thought. Link to comment Share on other sites More sharing options...

You will not get an indication that the PCM has been reset other than whatever problem you may have been having goes away. Link to comment Share on other sites More sharing options...
