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 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

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 ..

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 big  basta-d. alternater- 2yr old..... Stomp, i know its a ground, simply because once the car is drivin, and the sun is out and all is dryed 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.....

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.

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 no difference, or no fix to the e-ghost problem......that being said, i have read the post..9792/tm.htm and agree 100%..... all of our time is limited and 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 car 1 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?

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

Stomper.....so i'm back in town and with the sts......however, while gone the week, i had my 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, i ran 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 has a 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 it be 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 only when the e-ghosts are all most visible.(all is going hay-wire).....    :-) tx again

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,c1780, 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

Here are the code descriptions:
 

U1056 - Loss of Communications with RSS

U1066 - Loss of Communications with RIM

U1192 - Loss of VTD Class 2 Serial Data Com

U1255 - Class 2 Communication Malfunction (Serial Data Line Malfunction)
 

C1650 - RSS Control Module Fault

C1725 - Right Rear Damper Actuator Short Circuit to Battery

C1726 - Right Rear Damper Actuator Short Circuit to Ground

C1735 - Compressor Relay Short to Battery

C1743 - Speed Signal Fault

katz.......whats up with that??????    never heard of such a thing........... you?  i got to watch what i say....... does the word cracky mean anything to you??????

hey katz....give me your thoughts on those codes...... or isn't that your expertise......

Not the first time I've heard this but I think he missed a step. I believe you need to short one against the other while the positive is still attached. I do a similar thing on my GMC to reset the SES light, diconnect one lead to the computer then crank, truck won't start but it cranks, Reconnect and the SES light is out.

ok.... let me know how i would do this..... i'll try anything to get rid of the Gremlins....... should i disconnect the neg, and touch the pos with it???

Lets find out for sure before we start frying the STS. Stay tuned, time for some web surfing!

thanks dude

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:

• 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.

After that check the codes again, hopefully the gremlins will be gone.

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

hey Katz, Stopmer...... i did this test, pulled over and shut the sts down and ran codes....... DIM U1065....DIM U1066....IPC B1652....IPM B1652.....IRC U1016.......and PCM P1063.....came up........cleared them, turned around and brought her home....at 85 to ...well, lets just say out of the 8 min of 55mph  for the test, it took me 2 min's to return.....again checked codes and NO CODES....????????????? welllllll what do you all think??  thanks guys
