Christian Shawn Bledsoe Posted March 8, 2014 Report Share Posted March 8, 2014 Ive posted so many topics that im ready to set this car on fire.....lol....1997 Deville 140 miles these are the issues with the IPC once displayed low oil turn off car...oil level was fine hasnt happened since cd player is aftermarket and powers on by itself and then powers off and wont come on at all Ipc displays service airbag ipc displays theft problem car might not restart gas gauge..heater controls dont display ipc blacks out and comes back on defroster comes on by itself and i cant turn it off I replaced the battery and cleaned all terminals but the theft system prevented me fom starting car carr so i dissconnected battey and let it sit over night reconnected and it started right up to car to cadillac dealership..they flashed the ipc it worked great for a day then started doing werid things all over.they have no idea whats wrong with it.. im at a loss and spoke to a GM tech that rebuilds IPC digital panels..he said hes had this issue before and its a body ground... I think i should take out the ipc and send it off and have it rebuilt''''''HELP!! Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted March 8, 2014 Report Share Posted March 8, 2014 The tech's guess sounds good -- the system does need a clean ground and the behaviors you describe certainly sound like an electrical connection problem, not a problem specific to the panel.

Christian Shawn Bledsoe Posted March 8, 2014 Author Report Share Posted March 8, 2014 Ok thank you! other than the battery do you have any ideas where other grounds are? also i replaced the heater core which leaked everwhere on the passenger side is there a connector that could have got wet?

Bruce Nunnally Posted March 8, 2014 Report Share Posted March 8, 2014 So job 1 for maintaining a 97 Deville is you need to start monitoring ebay and other sources and find a Helms Service Manual for cheap. These are the encyclopedia for maintenance and repairs for your specific model and year. Like this one http://www.ebay.com/itm/1997-Original-Cadillac-Eldorado-DeVille-Seville-Shop-Service-Manual-Volume-1-2-/310887332341?pt=Motors_Manuals_Literature&hash=item48625439f5&vxp=mtr although it looks a bit beat up I don't have a shop manual for the 97 Deville. My 96 STS ground distribution for the IPC included turn signal, HVAC, glove compartment light, headlamp, cigarette lighter, door switches, rear view mirror, flood lamps, seat switches. So any frayed wiring or shorts along any of these systems could lead to a loss of ground. There are 15 - 20 diagrams in total for ground distribution. Certainly any breaks and repairs you have done would be candidates for where the short is. Also the aftermarket cd player would be a prime suspect for something not wired correctly.

Texas Jim Posted March 8, 2014 Report Share Posted March 8, 2014 Have you tried completely disconnecting the aftermarket CD player ?? I suspect that it's erratic and unusual operation may have something to with your other electrical issue. Link to comment Share on other sites More sharing options...

Christian Shawn Bledsoe Posted March 8, 2014 Author Report Share Posted March 8, 2014 is there a main fuse under the hood that goes to the ipc? i jigged the fuse block and it seemed like eveything started working for a second Link to comment Share on other sites More sharing options...
winterset Posted March 8, 2014 Report Share Posted March 8, 2014 The cars systems communication is on the purple wire. Make sure no one tapped into this wire anywhere. Also you might want to remove the rear seatback by unscrewing the 2 bolts from the trunk. Check all the connections back there. Also if you have an aftermarket radio, you shouldnt have chimes for warnings unless an aftermarket product was installed. Any of these items are suspect.

Cadillac Jim Posted March 11, 2014 Report Share Posted March 11, 2014 is there a main fuse under the hood that goes to the ipc? i jigged the fuse block and it seemed like eveything started working for a second I would pull that fuse and throw it away, clean the use block and the connections for that fuse inside it, and use a new fuse. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
