I have done the resistor pass lock on my 2002 impala (47000 miles) and the security light is still on. The car has never stalled or stranded me the security light is on steady then battery light and then service engine soon cycles on and on. Does this mean I need to take it into a shop or dealer to have a new BCM installed ? What options do I have ?

Not sure what you mean by doing the "resistor pass lock". Get the car scanned and you may figure out why your SVS light is on and off and get the issue fixed. It may be why the security light is coming on.

Thanks for your response. I used ZeeVerts post from May 2011 on how to bypass the security light problem using a determined value of resisters on the black and yellow wires coming from the BCM to the ignition switch. I was expecting not to see the security light when I started the impala up. But there it was just like before thus my question does this mean I need to replace the BCM. I think your answer is right in that I need to find some one to scan the Impala to find what is the cause of the light being on. Thanks again

Don't get on here much this time of year..Yes a scan is the way to go..Imo if the car is running I don't think it is a passlock problem.

Have you checked the battery? When my battery was on the way out in the Monte Carlo I had all sorts of random issues.

Yes I replaced the battery when the security light first came on. Then when it went dead after a couple of days. I done a parasitic test and found that the radio was drawing 1.80 amps all the time . So I have pulled the fuse for the radio and will have to deal with that problem after I get the security light problem fixed . I think the radio and the security light problem are linked and when one is solved both will be solved. I did a scan and my OBD II scanner registered no codes.

SES code is usually a B (body) code; unless you have a high end OBDII scanner all you will be able to read are P (powertrain) trouble codes. Airbag codes are A and ABS codes are C - if you have a really high end scanner you can read everything.

Thanks for your reply. My scanner is not capable to read the codes mentioned. So I guess my only option is to put the system back together (remove the resisters on the passlock bypass) and find a shop that can scan it for me.
