#11 of 433 Help Needed...BCM??? by mzmatthews

Feb 24, 2006 (2:58 pm)

I started experiencing the same problem with my 2002 chevrolet impala with the battery light coming on then the security light..soon the "service vehicle light", then then the ABS along with the brake light would come on then go off...thought it was the battery, had it tested along with the alternator..those turned out to be good..was told my serpetine belt had cracks, had that replaced. All was good for a week and then the same problems started occuring again. I am at my wits end for I am a single mom and all i need is for my car to quit on me in the middle of no where...could it be the BCM? Somebody PLEASE help me!!! I called the Chevrolet Service Dept and of course I was told to bring it in for them to charge $112 to tell me what is wrong...the guy would not try to help me in anyway ..and if it is the BCM what is the longest I can go until I can get the money to actually have it fixed?
Any comments or suggestions are greatly appreciated!!

#13 of 433 Dead battery by rockunzzi

HELP!!! Out of the blue, one morning I went to start my car and the battery was DEAD. No warning, no lights, no message, just dead. I jump started it and all was fine again for a week or so, then the same thing. This went on for a few days, had the battery checked and it was good. I pulled the negative cable on the battery and ran a multimeter in series on it and it was pulling way too many amps, so I pulled the fuses until I found the culprit. It was the BCM/Cluster fuse. A cheap quick fix was I ran a switch on that circuit and turn it off when I park my car for the night. That seemed to fix the problem, until about a week later, the battery went deat again without any juice going from the fuse box to the BCM. Does anyone have any ideas where I need to turn to next?? the dealerships want to just start changing parts on me and I don't agree with that.

I had the same problem with my 2001 Impala,dead battery.after many trips to the dealer,and along ten day stay,they found the problem.My radio stays on ,and that was apparently draining the battery. The dealer first replaced the BCModule,next was theICP Board,next was theIP Cluster Broard and the Radio.IHave not had any problems since.Fortunately this all happened a week before the three year warrenty was off.Hope this will help you.

From White Rock, Canada, just north of Blaine, Wash. - Over a number of months, I had my Impala towed to the dealer 5 times. I think the problem is finally fixed. The ignition switch was shorting the BCM, and so with both replaced, I think they finally got it. I had extended warranty for the first BCM replacement, then all the other visits were on the dealer's own warranty. They changed the BCM a second time two weeks ago, then it wouldn't start again, and they got a code to change the ignition switch, or cylinder. I might just buy a different car next time, what do you think?

My 2002 has been towed into the dealer 5 times in the last two months for the same problem. First time they said it was a light relay, 2nd time couldn't find the problem, third time they said it was a Bad Sears Diehard (2 weeks old, third battery in car doing same thing)but they changed Body control Module, fourth time they had a six days and said it was fine-no problem. Five days later...Dead again.Picked up car today after they said they finally duplicated problem caused by bad Negative Chasis Ground Cable. Let's see how long it lasts this time.
GM Assistance line basically said since I have the extended warranty they'll keep fixing it (or guessing).

If it happens again, tell them likely it's the ignition switch shorting out the BCM. It probably is as good a guess as theirs, and that actually was the case for me. Changing both seems to have solved my problem.

I have the same problem. (02 Impala) Once in a while the SECURITY light will flash and sometimes stay on.
 
I try to start the car and the ignition is dead.
Battery has full charge.
If I wait 10 minutes it usually starts.
 
Isn't the PASSLOCK system separate from the BCM?
 
The dealer told me to try different keys, apparently there is a computer chip in the key.
 
Tried the spare key, and still had the same problem!! Can any one help?

#19 of 433 2000 Impala will not start. by dingo299

Mar 17, 2006 (7:42 am)

I drove my impala into the garage last night and the came out this morning and all things seemed normal. But the car would not even try to crank. All lights and guages fine. Battery in good condition and charged. Still not even a signal sent to the starter as it seems to me. What is the deal on this??

Does the Security light blink intermittantly?
I am having a similar problem with my 02 Impala.
Another posting on this site suggests that the BCM and Ignition switch could be the root of the problem.
 
Chevy PASSLOCK/SECURTIY sucks!! The Impala BCM's are Junk!
 
I've had the BCM replaced on my 02 Impala when it only had 39K on it!!
 
I have 70k on my Impala and I suspect that I have the same problem again!! I guess that the BCM only works for 30-40k than you have to dump $400 to get the dealer to install a new one. Impalas are lemons!!
