2002 Oldsmobile Silhouette 6 cyl Front Wheel Drive Automatic 98000 miles
Ok while driving it takes about 30 miles down the road and then the gauges act erratice. Sometimes just one sometimes all. Then the radio will shut off, gauges shut off and the BCM will ding at me for low fuel. Then all the gauges will come back the door locks reset themselves (by unlocking then locking once) and the radio turns back on. Sometimes after this happens the radio shuts off imediatly after the key is removed other times it doesnt shut off when the door is opened (but the lights come on) (so I have to remove the radio fuse then reinsert and it fixes it). It started out every half mile but I have since replaced the BCM, Ignition switch, battery (it was 9 years old), and the alternator (was giving inconsistant readings on my volt meter which is now giving me consistant readings). Every time I change something it gets better to now it only happens after 30 miles and then doesnt do it again for another 30-40 miles.
I have removed the IPC and checked all the wires going into the cluster and found nothing wrong. I am trying to figure out how to check the passkey system so that I can verify if the pk3/theft lock is bad or not as I dont want to change it unnecessarily. The other items I replaced were all bad but didnt fix the origional problem.
sorry I did not see the edit button before now lol. Also the DTC loses power as once I had my Equus scanner connected to it recording live data and it lost connection with the pcm when everything else lost power and went awry. Sorry forgot to add that I have checked the body grounds under the hood and then the ground lug under the drivers side between the steering column and the cluster as well as the ground on the passenger side by the blower. When these problems occur the security light stays on until I shut the vehicle off wait for it to cycle through all the messages that display besides security (like rear hatch ajar, door open, battery power etc). As soon as those are done van starts right up. The engine does not stop running when this happens either as I will have the cruise control on and the van keeps that speed.
have the same problem?
