#126 of 6387 Passlock by dave5319 Dec 10, 2000 (8:18 pm)
Don't worry about using the "cheap" key there is no difference. Everything is in the ignition switch. I found the paper that explains this, the link is: www.internationalelect.com/vatts.htm There it will show you all the different types of passlocks. Dave..
#127 of 6387 Moving rear seat by krey Dec 10, 2000 (8:55 pm)
Has anyone tried to have the rear seat in a new Tahoe/Yukon remounted towards the back to gain a little leg room? Another 2-3 inches would be VERY nice.
#128 of 6387 ( krey) Knee room /slide in Second Seat by don434 Dec 10, 2000 (9:49 pm)
I`ll admit I`m a senior citizen and haul several senior friends. My chief design complaint with every chevy suburban since my very first - about 36 years ago - has been that it`s very hard for seniors to sit on the corner of the second seat and swing your feet around to clear the door post. There is not enough leg room to enter easily. I hope some one responds positively but I don`t think it can be done without a interior redesign. The floor suddenly is elevated just at the point you need to slide the seat to the rear. My mom is 96 years old and only about 5 feet - 2 inches tall. With her short legs she still has trouble getting in the rear. My wife reluctantly gives up her front seat whenever my mom rides with us. Are you listening GM! My sister in law also complains it`s hard to get in and she is only 46 so it`s not only an old fogey problem. As far as the physical characteristic of my part time nurse is concerned - I won`t comment except to say that: If my wife happens to be next door when the nurse arrives - she always returns home relatively quickly.

#129 of 6387 (zzack) Theft Deterent - Passlock Keys by don434 Dec 10, 2000 (11:56 pm)
GM has effectively driven me nuts trying to come up with a simple clear cut explanation. This section of the manual covers pages 8-841 through 8-882. Within two pages of the start of the section is a warning that under certain conditions an open in the pass-lock sensor system may NOT set a diagnostic trouble code ( DTC ). A scan tool is the auto mechanics major tool to locate troubles. Without DTC`s being set it`s hard to diagnose. On page 8-851 step 9 talks about RE-PROGRAMMING the SEED and the KEY.This is needed after you charge parts in this circuit. On page 8-880 advises that: The system is similar in concept to the passkey system.However the pass-lock system eliminates the need for a KEY MOUNTED RESISTOR. This system blocks the operation of the fuel injectors if the correct key is not used. All of this junk is fine but HOW IS IT that many have used a standard key - cut at many different key shops - and the truck has started and runs fine. If it was only one or two cases I might feel better. Makes you wonder just how efficient is GM`s Theft protection. Again the Service Manual advises one thing - practical experience dictates another. Did the original design intent cost to much or wasn`t easy to keep working - who knows. The service manual tells me outside GM keys don`t work - our friends say they certainly do.??????

#132 of 6387 Passlock (don434 & dave5319) by zzack Dec 11, 2000 (1:35 am)
Thanks for your replys. Don't know who International Electronics is but if what they say (see below) is true I fail to see any value in the system and why hasn't GM changed their Documentation or informed their Dealers? It's not that they haven't had time. Dave5319 I agree that a "cheap" key seems to work so I guess this is another little mystery of life. "Introduced in 1996, GM has changed the VATS anti theft system to Pass-Lock system. This is a similar device to the VATS system, in that there is a resistor present during the start cycle. However, in the PASSLOCK system, the resistor has been placed inside the ignition switch, instead of the key."
#133 of 6387 ? about rear dust guards by dejr_3 Dec 11, 2000 (12:16 pm)
Has anyone installed a rear dust guard - I think that is what they are called... We live in Boston and the rear window gets really dirty with the road spray. I assume that the rear air deflector would partially solve this problem. Has anyone had luck with them - do they work? thanx
#134 of 6387 Onstar unreliable by frankindc1 Dec 11, 2000 (1:20 pm)
I was first on the scene of a car burning in the heart of DC and pushed the emergency onstar button. The radio cut off but nothing happened. Help came later so I took off and called them when I got home. They said I should disconnect the battery to reset and/or get it serviced (great). Then the DC police call me asking if I got carjacked and that Onstar couldn't locate my tahoe (the guy I called didn't know this happened). In the morning, I pushed it and it connected to the phone call feature--then later a guy comes from nowhere and says "sir are you there?" So he says it works fine. It's comforting that it doesn't work when I need it.......
#135 of 6387 Passlock link (zzack) by bstrandb Dec 11, 2000 (3:01 pm)
The document I tried to refer you to was a petition for exemption from a federal parts marking standard, based on the effectiveness of Passlock. To get to the document try going to http://www.access.gpo.gov/su_docs/aces/aces140.html , then search on 'GM Passlock'. Choose the document titled "Petition for exemption...'. Here's an excerpt: 'Passlock...features an electronically- coded lock cylinder rather than an electrically-coded ignition key. Specifically, when the sensor detects proper lock rotation, it sends a code to the body function controller. If the correct code is received, fuel is enabled. If an incorrect code is received, fuel will be disabled for a ten-minute lockout period during which any attempts to start the vehicle will be unsuccessful."
