electric issues e-ghosts...rear integration module, (RIM) - Page 2

ok guys.......... keeping you posted, out this morning...my coffee run.... let the sts run all the time......trip took 15min.....sts warmed up to running temp.....home....parked and ran codes......i couldn't keep up......i think it would be better if i told you which ones didn't come up.......my first ghost thru the dash was the fuel gague flipping to E, then back to full...then 3sec she goes back to E and sets  (tank is full)......then went in for coffee, let it run......back out the security yellow light on...drove, and then get mess...SERVICE SECURITY SYS......thats a new one....  intermittent outside mirrors, inop....dr locks inop.... entire inside e-ghosts................any thoughts??????  oh yesterday my bose started cutting out (couple sec) then on.....I CAN"T HAVE THIS......need my radio.....    this car needs an exercist........HELP....please

Computer shot?

 
ok .. remind us what you have done so far .. item by item?

starting with my #1 question .. have you disconnected connector by connector, sprayed with contact cleaner and lubed with di-electric?   that would also apply to the huge connectors on the computers themselves.

let me put it this way .. have you ever plugged something at home into an outlet and had to wiggle the plug to get it to work?  well, you dont have that option in a car.    the dozens if not hundreds, of contacts have to be PERFECT !





.

ok.... i guess i haven't found the connection(s) that is the bad....... "where is the computer on this sts".......and do you think it is one or two bad connections with the 15 grounds on this car....i do.     ......and can we rule out or key in on one or two  specificly?.......
what i'v done.....1- cleaned and di-electric the two grounds under rear seat.. (i still think, its there, and am going to redo them) the main battery 1 and
                          one that comes in from the trunk...... this was done last year
                         2-also had g100, and g102 cleaned by  a tech, here where i live.
                         3- new cluster   got really takin on that......
                         4- new ignition switch
keep in mind.... the sts ran new all summer long, no E-Ghosts......its when the weather turned damp the E-Ghosts reappeared
thanks Stomper....thanks Katz......thanks Stealth............. you guys are the best

"when the weather turned damp the E-Ghosts reappeared "
THAT my friend, points  to only TWO things. 
a) oxidized connections
b) a cracked / damaged electronic component or connector, including BCM / ECM computers. I actually found one such bad component by applying a hair drier on high heat to each item see when the issue went away.

"3- new cluster   got really takin on that......"
a highly suspect "electronic" item as well as the connections to it

if i was a gambling man, i be betting on these.
Of course, what info you provide has to be correct.

Stomper......all info is correct...... i agree when the weather turned damp...etc............my problem, is where to start...lol..... what are the most vunerable connections in your opinion?......or should i start from front and go back.....i have a ground document id# 162408..... 1999 seville   though now wondering if it is the same for sts.......... i wish i knew how to load this, though  its from GM...maybe you could check    no big, i'm going to start with the grounds..... would you agree?
thanks again

     katz. trying to narrow down where to start looking for bad connection.................. the first 4 codes... what would cause them, and is there a connection/ ground that i could check?........tx.......rickyd

 
i start with the connectors to the computers, then restart at the front bumper and hit every connector, every bus terminal, all the way back.  you can do all that on one day if you have good lights and small hands for the tight places.

get tools to undue the connectors and tie-wraps to secure the ones that have broken latches.

thanks Stomper.............  sorry, just don't know where computers are........ i think there are two.........let me guess????? under dash(somewhere), and under rear seat????  how'd i do?

I think you should get the car scanned by a good shop and diagnoised. Loss of signals usually mean power supply interupted or wires disconnected. How's the battery, I know it sounds too simple, hows the alternator too?

your absolutly right Katz... i myself admit, its over my head......i called my gumba Vinny..he is AC Delco certified....he'll get it fixed.. ...... i have one more question though, and i won't post this thread untill after the sts comes back from Vinny's.......
Question..... the sts, after my coffee run this morning had two CURRENT codes......ipc u1255, and ipm u1255........ any other time all the codes we discussed were in history....... does this help pin-point the problem????       BIG THANKS to all that helped with this......you all will know the out come as it goes down.......... 
so what say you on these two codes?      thanks katz
rickyd

katz in post #36 whats the difference......ipc u1255 code, and ipm u1255 code?

good morning.... well now that the season is starting to change, ( nights are cooler and wet, and big moister on car in the morn) boy my electrics are wacky! fuel gauge, instrument cluster, security light, auto dr unlock, temp gauge, all have issues............ can anyone pin -point what ground or connection this might be??? there is also a relay that sometimes will buzz after shut down..... it is the cvrss dampers relay....... a simple disconnect of the battery for a while will shut it off.   i just had it in for a service stability system dic info, that was poor grounds at g100 and g102............so anybody?............ill be standing by..........katzmans? you out there?  1999 sts
rickyd

dang .. where was this?

i be replacing the buzzing relay yesterday,
check battery - how old is it? what type?
check alternator,
check battery ground,
check other grounds.
codes?

then report back ..

    i said wasn't going to post untill having vinny look at sts....though went out for coffee run this morn and it wouldn't start......! i  know stomper you wanted me to check battery, and alternator......both replaced with Delco parts june of '05.....79-6 delco batt....3211830 delco alt........ Question..... going to have checked......doyaall think that batt has bad cell?......... and would that cause all the E-Ghosts.......doesn't seem right to me , but then im not a tech...............tx guys              oh...post 37....????? please
rickyd

there is a reason we call them ghosts .. they show off where they they dont live.

as long as you go with the "i thinks"  the ghosts will seemly go through the hoops endlessly.   you  may hit where they are visiting only to see them travel elsewhere.   you have to hit their home.

sit down on a table, far from the car, writing down the LOGICAL possibilities based on the FACTS, prioritize, and systematically hit then one by one, w/o skipping a beat.  usually it isnt that hard, it does require patience.   for the most part, when you find the problem yo will be surprised how simple the fix is.  

lol   thanks dude.......

Does car still has the flu?

slowroll..... YES.....and its getting worse.......just got back last night from 900 mi trip, and the GREMLINS were at it big time......this is a new one, the radio, and drv dr back lights are increasing, and decreasing intermittently, among many other things.....the car goes down the road brand new...powertrain is 110%....it the electrics inside..... im trying to get it into vinny, GM DELCO certified......but our schedules aren't working, so i'll do what ever the Forum guides me to do........what say you, slowroll?

Sorry to here car is stll ill, I suggest check both G200 and G201, they are buss bar type grounds.Peel plastic box open and look for corrosion. Being you have all these suspension codes, you could have that system checked first or unplug module when it happens again, if it clears up it could be the cause. U codes are caused when modules are not talking and any one of them could be the cause.It can like when your kids are all fighting, and you're trying find out who started it. Its not always the obvious one.Hope it helps

Oh, by the way G200 and 201 are on both A pillars behind step mouldings, thought you may want to know.

those are the ones that i cant find....... tell me exactly where they are, please....... you say peel plastic box open?.....A. piller?......buzz bar type grounds?.....give me a little more info..... as to where they are.......are they  in a plastic box?
thanks slowroll......
rickyd

ya know.......? after thinking 'bout this a little, and with all you guys pipeing in to help......BUZZ BOX......... why didn't i look in the buzz box?.......well, found and took apart buzz box for grounds 4,5,7,8,9,12, and15...... (couldn't find grounds 2,3, and 6)........ took 20mi run, and no Gremlins!!!   i don't want to say that to loud, the sts is right out side, and might hear me....lol.......  we'll see......again THANKS to everyone, stealth, gary, katz, slowroll, and all.... lets hope the Gremlins are gone, and on their way to Halloween.

with the help of one of our friends, i am still working the 300 series grounds/ buzz box..... i think your the one that said "all can be done in a day, with the right lights, and TINY LITTLE hands.   i found where they ground bolted, but i can't get my hands on the buzz box to clean....will have to take seats out.....WHERE are the computers on this car please? also where is ground 306? (the only one i cant find) thanks to all
rickyd

JUST AN UP DATE......GOT TO GROUND/BUZZ BOX 300 TODAY (ALL LOOKED EXTRA CLEAN), GOING TO TACKLE GROUNDS 302, AND 306 TOMORROW......THAT WILL FINISH ALL GROUNDS..... SLOWROLL HAS SUGGESTED THE RIM, AND THAT MAKES SENSE TO ME.......SO IF ALL GROUNDS ARE GOOD THAT IS NEXT..... I HAVE FOUND A RIM FOR $215.00  (does that seem reasonable?)......I'LL INSTALL IT MYSELF......IS THERE ANYTHING THAT I SHOULD KNOW, OR DO WITH THIS INSTALLATION?...... OR DOES ANYONE KNOW IF THERE IS A CHECK OR A TEST FOR THIS RIM?
THANKS...............

With a GM tech 2 when condition is occurring look for the non communicating or missing module.
