electric issues e-ghosts...rear integration module, (RIM)
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 whilewill 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 bestanding by..........katzmans? you out there? 1999 sts

RE: electric issues e-ghosts...all over
Stomper..... thanks for the response, it must have been an off week when i posted :-)...... buzzing relay.. tryed that, new one, did the same thing....just thought that might give someone a heads up to pinpoint....... battery, 1-2 yr old and a bigbasta-d. alternater- 2yr old..... Stomp, i know its a ground, simply because once the car is drivin, and the sun is out and all isdryed up, things are fine, with a slight bounce in the fuel gague, at times.(goes to E then back)( could it poss be the sending unit???, and would that inturn through other things off?)..... i know there are about 15 grounds on the car (99 sts). g100, g102 have been redone a short time ago(service stability system)...... which one, or where do you think i should look now? as far as codes????? i'll have to check them (if i remember how) when i get back home. out of town for the week..... THANKS again.....

RE: electric issues e-ghosts...all over
Got my own electrical Gremlins, rickyd, but not for this post.No one has ever called me Sparky, but I did track down a short in my daughter's Buick brake lighting system once, took over an hour and a half.

RE: electric issues e-ghosts...all over
Stomper, yes you are correct..... i knew when i typed that, that i shouldn't have..... though wanted to give heads up that the problem hits that relay, and may give a clue to the e-ghost...... i should have said i have exchanged relays, and found nodifference, or no fix to thee-ghost problem......that being said, i have read the post..9792/tm.htm and agree 100%..... all of our timeis limitedand sure don't want to waist anyones, especially looking for help. i didn't take offence, and thank you for your response.... i will, as i said get codes for you all to review when i return home saturday.....i hope you will assist my e-ghost problem at that time.
i have done the internal code check from inside the car1 time.... would you please refresh my memory on that please..... sorry for the past post rickyd hey Katz....trying to get all you guys straight........... |

I get this feeling that you are becoming a valuable asset to this site. You learn as you go and dont wear a chip on your shoulders. Those are very valuable traits in this community. Of course we will help where we can. Time, as you mentioned, is limited. We all have real jobs and come here as "volunteers" .. right? |
RE: electric issues e-ghosts...all over
thanks stomoper..... i to am working and grabbing a minute or two or three to look in....see whats up. i enjoy the Forum a ton, and like to help.....only when i"ve been there, if you know what i mean......
thanks again........oh getting codes from with- in the car....99sts..... which thread or post..please direct me. rickyd |
RE: electric issues e-ghosts...all over
Stomper.....so i'm back in town and with the sts......however, while gone the week, i hadmy lady friend run the sts for me.......well, as she stated..she started it and run it down the block, and back and shut it off...... well when she went out friday...it would not start...... my fault, i should have told her to at least get the car warmed up, or to take it to work, etc.....imo the cvrss relay stuck on and killed the batt...... sunday morning, start right up with jump and ran new..... though maybe, she somehow disabled the starter, because the batt seems to be back up in just a 3 mi jont...
so, iran codes.....yikes!!!! stomper it seemed as i told it to do "all"EVERY code came up in history. i couldn't write them all down........ PLUS, and this really pi____ me off. the sts hasa couple spots of oil under it...taat N* is spotless.....i sure hope it was from me topping it off before i left for the week.. ill have to watch it.......so bad to the codes.... i'll drive it today and see what if anything pops up that i can get a code from, this is good because i reset all codes and hopefully the one that pops up will give us a starting point ......tell me if i'm wrong in thinking that.......is there any one catigory i should be looking for??????......yea, if you don't mind' stick with me here, and i'll be back at ya with this.....stomp, thanks alot rickyd>>>>>> hey,? that cvrss relay that buzzes, only 4 times sense Jan 07. should itbe replaced, i did get a new one and put in in and it buzzed like the old one.the guy was nice enough to take it back and i returned it...... that seems to buzz onlywhen the e-ghosts are all most visible.(all is going hay-wire)..... :-) tx again |
RE: electric issues e-ghosts...all over
Stomper..... in short...... i have some codes..... u1066.....u1056.....u1192........ what do these codes tell us....... the E-Ghost is at the starting stage, and will grow from here......the sts started its E-Ghost after a short run back from dinner. 3miles at most.....the car ran fine all day after the reset............when i shut it down, there was a delay with the electrics.......dr locks not unlocking (going into park).....radio will play after dr is open...... tilt whl will not go up......inter lights will not come on...... it is like everything that should happen is delayed 5/6 seconds. it gets worse from here, like the little gremlins infiltrate as time goes on....... now, fyi, i live near the lake, and my property is next to a wet-land....so, "very damp" surroundings........ any info you can give?????
thanks Stomper rickyd ..............Stomper, as i said the gremlins infiltrate......just went out to move the car and ran the codes again......check this out!!!! u1255,u1066,c1650,c1725,c1726,c1735,c1743,c1760,c1 780, and c1769.........for some reason the u1056, and u1192 didn't show, oh i think i cleared....yes i did........... all i did was move the car out of the drive way and back......HELP.......again tx |

RE: electric issues e-ghosts...all over
Lets find out for sure before we start frying the STS. Stay tuned, time for some web surfing!

RE: electric issues e-ghosts...all over

RE: electric issues e-ghosts...all over
After surfing around here's what I think you should do. Clear the codes. You have a record of them here so maybe you want to print them out. I am assumimg you know how to clear codes. Then disconnect neagtive battery terminal for 10 to 20 minutes. Reconnect and then do the GM driving cycle as explained below:
Complete driving cycle will perform diagnostics on all monitored systems and can usually be completed in less than fifteen minutes. Performing a GM OBD-II Driving cycle: [ul][*]Cold Start In order to be classified as a cold start the engine coolant temperature must be below 122°F (50°C) and within 11°F (6°C) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run.[*]Idle The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire and if closed loop is achieved, Fuel Trim.[*]Accelerate Turn off the air conditioner and all the other loads and apply half throttle until 55mph (88km/hr) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.[*]Hold Steady Speed Hold a steady speed of 55mph (88km/hr) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.[*]Decelerate Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 20 mph (32km/hr). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.[*]Accelerate Accelerate at 3/4 throttle until 55-60mph (88-96 km/hr). This will perform the same diagnostics as in step 3.[*]Hold Steady Speed Hold a steady speed of 55mph (88km/hr) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.[*]Decelerate This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.[/ul] After that check the codes again, hopefully the gremlins will be gone. |
RE: electric issues e-ghosts...all over
god katz....... thats good stuff......... thanks....thanks alot for that time.......... i'll be on that this week end when i am off road..(doing that work thing).. and be back at ya...... i'm hoping that will work...... i was about to have it taken to the shop......... now i'll give this a try...... when i got the sts in jan it was doing this..Gremlins all over.......thought it had cured during summer, reworked 4 - 5 grounds....... now all sorts of issues, as you have seen..with codes......... thanks again

RE: GM and Cadillac electric issues e-ghosts ... all over ...
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 ! [align=center]PERFECT ! [/align] . |
RE: GM and Cadillac electric issues e-ghosts ... all over ...
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 |

RE: GM and Cadillac electric issues e-ghosts ... all over ...
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. |

Question..... the sts, after my coffee run this morning hadtwo 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 |

Cadillac GM electric issues e-ghosts...all over
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. |
