#309 of 447 2007 chevy impala Keyless remote Problems
Jan 21, 2009 (1:58 pm)
I have a 2007 Chevy Impala LS. I recently have been having problems with the keyless entry. The remote will not work when I want to unlock the car. After I use the key to get in the car the and physically open the door the remote will work. When I shut the door and get out of the car I am able to use the remote. After a couple of minutes the remote will not work. I have tried two different remotes and I have the same problem. Any help would be great.
#310 of 447 Possible BCM Problem
Mar 27, 2009 (10:37 am)
For the last few months my air bag light stays on the when the car is started. Recently I have gotten numerous ABS/Trac Off and Service Traction System messages. Both front wheel hubs have been replaced (one had frayed wires) but this did not correct the problem with the traction lights. Could the frayed wires short out the BCM? What exactly does the BCM on the 2002 Impala LS control? I guess I am lucky that I don't have the passlock problem or the leaking intake manifold yet...
I have almost every other one though:
Hazard button/blinker shorting problem
Transmission hard shifts
Service Traction System with trac off/abs lights
Service engine soon (stuck thermostat)
Accessory outlet in front does not work
Steer shaft rattles
Break wearing problems (all four)
Warped Rotors (rear)
Head lights randomly shut off / multifunction switch broken
Heated seat driver side dead

I had a similar problem with my 2003 Impala.
My problem was the Body Control Module. (BCM)
#314 of 447 2005 Impala LS Electrical Issue
Apr 23, 2009 (5:48 pm)
My '05 Impala has run pretty well overall since I purchased it new in 2005. It has 74k on the odo. However, about 2 weeks ago a strange electrical problem occurred and continues. The radio (XM/AM/FM/CD) started making poping noises from the speakers:
-XM would blank out, change channels then cutout entirely.
-AM/FM/CD would work. Then the AM/FM/CD would start doing the same.
-Low or no volume and total shutdown of the radio.
-Fuses are ok.
-Onstar is in the vehicle but I do not subscribe.
-The problem does not appear to be stopped or repeatable by tapping, moving bumping the radio.
I removed the unit, checked the plugs and wiring and did not see any problems.
I took the car to a local well known and reliable AC Delco authorized repair shop. They placed the radio on the bench and found "numerous" codes in the radio including a "Class 2" trouble code, which apparently refers to a loss of communication to the BCM. They cleared the codes with their TECH II, reinstalled the radio and connected the TECH II again and found no codes present. The techs also looked at the amp in the trunk between the speakers and told me it was not the problem type of amp they have worked on before. The problem seemed resolved until it started again. I also disconnected the Onstar module in the trunk. Radio worked fine for several days then started again. The spooky thing is now the speakers in the car will emit popping and motor boating sounds with radio off, no keys in ignition by opening the door. It is a random problem. I have seen posts regarding the BCM as a possible cause of numerous electrical problems. Could it be the BCM or wiring somewhere in the car?
Sorry for the long post-hopefully someone will recognize the symptoms and provide some clues as to the problem.
#315 of 447 headlights and battery lights flash
May 11, 2009 (5:31 pm)
initially i had a problem with the security light flashing and then my car wouldn't start. i had to wait 10 minutes for it to start back up. that's been happening for about a year. now for the past couple of weeks, the battery light and headlights flash. it does this the whole time i'm driving and after i park it won't stop until i use the keyless entry to lock the doors. i was told (no diagnostic) by a mechanic that this is a passlock issue and that bypassing the passlock will resolve it. i was told that getting a remote starter would solve the issue since a bypass module has to be installed with the remote starter system. i got this done yesterday. i remote started the car and no flashing lights. as soon as i turned the key to the on position, the battery light and headlights were flashing. what could be causing this and how can i fix it???

You need to replace the BCM (Body control module)
I had the same problem with my 2002 Impala. Headlights flashing and dashlights blinking. Once the new BCM was installed everything was fine. Brace your self for a $400. repair bill!

I thought the BCM was the problem, but I was hoping there would be another solution. I just don't understand why GM hasn't recalled these cars for BCM failures. It seems like a very common problem with GM vehicles.
#318 of 447 02 Impala ABS light on
Jun 16, 2009 (5:28 am)
I have 02 mpala 114,000 miles and have had some of the problems in the the threads here but not all. radio changes everytime you turn the car on, volume of radio does not change to match noise, gas needle lately has been up and down. clicking and car wouldnt start(ended up being the battery)
Yesterday my ABS light came on and i heard the pulsing of the brakes. The light has went off and came back during the same drive. heard pulsing while i was turning but not every time. any help on what a fix for this is or how serious this problem is.
