Question about 2002 Chevrolet Impala

Recently replaced BCM

Dealership had problems programming the new BCM, but did eventually get it programmed. Unfortunately, it now seems I have lost the ability to reset my Tire Inflation Monitoring system (cant reset with light switch OR through stereo menu) and my Air Bag light is now steady on. Dealership wants to charge $120/hr to find out why.. Help??

SOURCE: Tire pressure monitoring system

Don't know that much about these but depending on where you bought ur tires they might service them for free, I know places like big o and discount both service tires for free. My guess would be that the batteries just need changed since they're supposed to last ten years and the car is 11 yrs old.

SOURCE: Tire Monitoring System

Most likely have a pressure sensor bad. Have you had the tires replaced recently? The sensors are easy to damage when mounting and dismounting tires.

SOURCE: Tire monitor reset 1999 Corvette

You can do this if you have a strong magnet. Go through the options menu until the screen is clear with the key on engine off. Then hold the reset button until it says key fob learn. I think it was the e/m button I hit to go to the next screen. Then it has the tire relearn procedure. It will tell you which tire to put the magnet on. Place magnet by the valve. it should beep. go to each tire in the order it tells you and you're done.

Do bcm need to be reprogramed

Has to be programmed ,yes .
Body Control Module (BCM) Replacement
If the BCM is replaced, the following procedures must be performed in the subsequent order:
• BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for replacement, setup, and programming.
• Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent.

A new body control module (BCM) must be programmed with the proper regular production option (RPO) configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the RPO available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
• The battery is fully charged.
• The ignition switch is in the ON position.
• The data link connector (DLC) is accessible.
• All disconnected modules and devices are reconnected before programming.
To setup a new BCM, access the Vehicle Control Systems in Computer/Integrating Systems menu on the scan tool to program the BCM. Select Module Replacement/Setup and follow the instructions on the scan tool.
If the BCM fails to accept the program, perform the following steps:
• Inspect all BCM connections.
• Verify that the scan tool has the latest software version.

How i can replace BCM on Gmc sonoma 2000

Replacing the BCM is easy , There are some steps that need to be followed but still easy ! After the new BCM is installed that's when the average person gets into trouble , because they don't have the knowledge ! They replace the BCM an it won't start an other thing's won't work . Replacing a BCM is best left to the dealer or some other qualified repair shop . It needs to be programmed an then Passlock Learn procedure has to be done. You may be replacing it when it doesn't need replacing . What problem is your vehicle having ? Have you had it checked for DTC'S - diagnostic trouble codes ? An not OBD2 codes , BCM codes won't turn on the check engine (MIL) light .

2001. Where is the BCM fuse?

Under right side of dash. In order to remove hvac blower motor, you have to move bcm aside. I couldn't find a decent picture.
I just wanted to add, a new bcm will have to be programmed, probably by the dealership.

Program bcm

Well unless you have access to some very expensive car computers and software that is strictly a job for a dealership unfortunately and it's a something that they charge you about an hour of service to do which will run you about 105.00 dollars plus tax. Just had one done and I'm a mechanic. G

Need to program new remotes for a 2009 chevy hhr

As far as I know you need a special tool (Tech II) from Chevrolet to program the remotes. Don't think you can do it on your own. You can double check your owner's manual but unfortunately I think you have to go to the dealer.

My 2001 L200 Saturn has body control module problems. The mechanic just had it reprogrammed at a Chevy dealership, but he didn't replace the BCM. We've had it back for a couple of days, and so far, it...

reprograming is very common, this is done all the time even with newer cars, some times cars new newer or diffrent programing installed in them and dealer is the only one that can do it unless someone has a dealer scan tool.As far as replacing it would depend on the problem and i think the dealer would of told them the computer was bad. hope this helps.

2003 Saturn Ignition and Security System Troubles

Sorry to say but it's probably the BCM (body control module) that's going in her car. The BCM controls everything inside your car, from the gauges, locks, daytime running lamps, ABS... and yes the security system. I have a 2003 L200 which had the same problem and I had to replace the BCM at some cost ($400-$600) depending on where you go. The L-Series Saturns seem to have a problem with their BCMs and it seems that it's pretty prevalent. Unfortunately it will only get worse as time goes on and it's not something that you can do yourself as it needs to be programmed by the dealer. You also will need to get your remotes reprogrammed as well with the new BCM. Hope this helps.
