#1 of 9 pulling DTC codes from the computer by llaupert Dec 23, 2007 (7:54 am)
This morning I had the service engine light come on - when I got home I hooked up my OBD 2 meter to the port and no codes showed. So I think I set one in the DTC computer. I have never had to access those codes. My Cadillac I hit a combination of on/off and scroll button up and the computer codes are seen on the speedometer display. I am certain with the 2000 Buick Lesabre something like that is possible. I could not find anything in the searchs - can someone please help?
#2 of 9 door locks by cae4300 Dec 28, 2007 (11:55 am)
My battery went dead from leaving interior light on in a 95 Buick Lesabre. Since then the door locks on passenger and rear doors will not open using the interior lock and unlock button or the key fob. Replies to this message: imidazol97 (Dec 28, 2007 12:06 pm)

Replying to: cae4300 (Dec 28, 2007 11:55 am) It might not be related to the dead battery.   Check the battery terminals for corrosion. Turn off all accessories. Put AC on off.   Disconnect negative terminal. Disconnect positive terminals and check both cable ends. Check for corrosion between the cables. Then reinstall after cleaning them to get bright metal.   I assume the key fob will unlock the trunk but not the doors? Does the emergency button work?   If neither of these are true, then HOLD the key fob unlock and lock buttons down at the same time while standing next to the car (with the battery reconnected, grin), just in case...   That resyncs the radio lock and unlock somehow. After 5=10 seconds there will be a short horn beep indicating it has resynced.   Beyond that you need to check fuses. There may be a fuse or relay for the door locks in a 2nd fuse/relay panel above the passenger's right foot on the bottom of the A-pillar. Remove the thin plastic panel with about 5 screws above the passenger foot-that's the hush panel to quiet noises from the heater and motor area. On top of the hush panel is a small sticker showing the location in the open panel of the fuses and relays. I recall there may be one in there.   Beyond that the locks may be part of the body control module. But don't go replacing it. I've rarely heard people say one is a problem. Check everything else first.   And just a thought..., how's your battery? If it's several years old and it ran down, this may be giving lower voltage than normal. It might be a time to replace it with a new one. At least have it thoroughly checked. Most auto stores and Walmart will do that check. Some will do a full recharge free-Advanced Auto, e.g. They hope you'll buy a replacement there if you do need one.
#4 of 9 Codes from 95 LeSabre by gettinit Apr 21, 2008 (2:07 pm)
Is there any way to pull the codes from a 95 LeSabre without taking it to a dealer or mechanic? On my 94 Dakota you can turn the key on and off 3 times and the light will flash in sequence giving you the codes that are stored. Just wondering if there are similar tricks w/ this Buick? Maybe flick the lights, honk the horn, turn the key and rub my head and pat my stomach kind of deal.....

Replying to: gettinit (Apr 21, 2008 2:07 pm) I think 93 was the last year for the ADL 1 or whatever the right name is. You shorted two terminals on the connector below the steering wheel and it gave out codes. But after that the 94 was an odd year for connectors but Advance Auto, Autzone, and others should be able to read the codes for you. They do it free.   That may be the year where it requires a specific set of cables and some stores myay have them or not. Check with them!   Are you getting a light? If it's not flashing 90% chance it's a gas cap leak, or some other problem with the pollution controls related to the fuel system.

Replying to: imidazol97 (Apr 21, 2008 3:31 pm) I already tried the AutoZone type stores, they say that it has to be a '96 or newer. I Did have a 91 Taurus SHO that I jumped certain terminals and it gave the codes, any info anywhere on doing that w/ the LeSabre? Replies to this message: imidazol97 (Apr 23, 2008 4:36 am)

Replying to: gettinit (Apr 21, 2008 6:51 pm) Check with more than one store. Different stores of the same chain use different equipment in this area. You need one where the manager chose to get the adapted cable.

Replying to: natesalgado (Oct 08, 2008 8:51 pm) I can tell you whaat the code is for but unfortuantely I'm unable to tell what to do to repair it maybe someone else can give you technical help for the problem.   P0771 Shift Solenoid E Performance or Stuck Off   I was able to check the code on this site. http://www.obd-codes.com/trouble_codes/   Hope that helps.
