angela29150 Posted August 28, 2008 Report Share Posted August 28, 2008 Hi, I have a 1996 cadi sls 32v northstar. I have had one problem after the other with this car. I brought it 3 years ago. Recently I had it parked for 2 months because of other problems. I just fixed those problems last friday. (8-22-08) Now it is reading on the dash "service transmission" and "service engine soon" but the car is running fine. I don't see a difference in anything. I had the motor oil changed Saturday (8-23-08) and the guy said my motor oil filter was barely on. These lights were off until Tuesday (8-26-08). Sometimes one light will come on, or both, or none. I am so upset because it is one problem after another. I wanted to know if anyone had an idea of what this might be and how much for repair? I am a single mother of three and God knows I can't afford nothing major! Is this a sign of something major coming for repair? Should I just keep driving it? Some nice person please help!!! Thanks, angela Link to comment Share on other sites More sharing options...

Thanks, angela Okay I just checked the codes (I was wondering how to do that) and it states: PC0603History PC0717History (sounds like trouble, uha?) AC1348History No : TCS, RSS, PZM, IRC, RFA, CCP, SDM CODES AND AT THE END WAS PCM WITH A QUESTION MARK BESIDE IT. Also the service engine light was off when I first went out to the car before checking the codes. Thank you in advance for any information!!!

I have searched hi and low. I have never added, changed or checked the transmission fluid since I brought it in 2005. My father got in a bad accident in May and I drove the car pretty hard to get to his location and to take him to the hospital, do you think I messed something up in the mist of this???

Ranger Posted August 28, 2008 Report Share Posted August 28, 2008 P0603 - Control Module Long Term Memory Reset No big deal. might be from pulling battery power. P0717 - Input Speed Sensor Circuit Low Input This is what set the "Service Transmission" message, but I'm not sure exactly what the problem is. B1348 - Very Low A/C Refrigerant Pressure Add a can (maybe 2) of refrigerant. PCM? was asking if you wanted to enter the PCM mode. Answer no with the INFO RESET button till you see CLEAR ALL CODES? Then answer yes with the ON/OFF button to clear all the DTC's. Angela, how many miles where on the car when you bought it? Do (did) you know it's maintenance history? Most of may Caddies (driven nothing but for the last 35 years) have been relatively trouble free, but I buy with low mileage and maintain them. Maybe you bought the wrong one. Don't condemn them all.

Ranger Posted August 28, 2008 Report Share Posted August 28, 2008 Angela, the "dipstick" is actually a cap with the stick on the underside, just like the P/S cap. It is under the intake duct on top of the transmission side cover. You'll see it over the drivers side fender. Link to comment Share on other sites More sharing options...

It had 120,000 miles on it when I brought it for 4,000.00. I have replaced the master cylinder, EGR valve, brakes, heater coil, A/C stop working, other sensors that I can remember right off hand. I had a 1992 Deville, I replaced the starter, alternator, wheel caliber, rebuilt transmisson, radiator, sensors, the car had almost new everything. It was beautiful. Burgandy with a rag top trimmed in gold. Then one day it would not start. I took it to a shop and they said it was a bad wire in the dash. They keep it for 3 weeks, could not fix it, and charged me 350.00 to get it back for their time for looking at it. I had it towed to Cadillac and they said they didn't want to touch it. I had a 89 cadillac deville and it was over heating and I replaced the radiator then someone stole it. My SLS is gold with a green rag top trimmed in gold. It is beautiful and I love it but I get tired of fixing it and then something else brakes. My income is very limited and I just feel like giving up on this car. I guess I just pick all the bad cadillacs. My sls looks so good people don't believe its a 96 but it is. Do you know how much the sensor is and about how much a side person would charge to fix it?

Ranger Posted August 28, 2008 Report Share Posted August 28, 2008 No I really don't Angela. The sensor is cheap. It's the labor that's gonna bend you over. It's known as the $20 part, $2000 deep in the trans. That said, I'm sure you can get off much cheaper if you can find someone who does side work. Perhaps subtly ask some of the techs at the dealership. Wouldn't hurt to wear a short skirt either. You've had some bad luck. My '92 Deville had 125K and was relatively trouble free. Likewise my '97 at 106K. Link to comment Share on other sites More sharing options...

Likewise my '97 at 106K. I will dig out my short skirt NOW!! I do have a friend who is a mechanic at Jones Cheverlet. I just don't like to wear my welcome out. He just fixed it on saturday and he is very reasonable. I just don't want him to get tired of me ya know. I have a 1995 ford mustand. I brought it in 1999 for 6,000.00. It has almost 300,000 miles on it and still runs like a champ. Original motor. I wouldn't trade that thing for the world. It has never put me down on the side of the road. Oh, I also changed the ignition on the sls and deville. I guess a cadi was not made for me!!! And the window master control for the SLS. The float in the tank will mess up at times too and every now and then I get service ride control on the SLS. I heard that may be the shocks. Anyways, thanks for all the information and I am glad someone gets good luck out of cadi's. They are beautiful but I am gonna stick to Ford next time around. I try to keep two buggies going so when one brakes I will have another to haul me and my kids around. You know you can't depend on people when you need them. Thank you!!!!!

Ranger Posted August 28, 2008 Report Share Posted August 28, 2008 WOW! Looks like I'll never bring you back into the Caddy camp. You have had some bad luck. Can't really blame you I guess. Lean on your friend again and see what he says about it. Is it actually causing any problems other than the message? Try clearing the codes since it is historical and see if it comes back.

Cadillac Jim Posted August 28, 2008 Report Share Posted August 28, 2008 I would check the wiring and connectors on the transmission before I decided that the sensor was bad. It started when you had an oil change, and it seems likely to me that they disturbed some of the wiring then. -- 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.

I am worried about this causing a major problem in the near future. I will clear the codes in the morning before I take my kids to school. Thanks, for all the info!!!

winterset Posted August 28, 2008 Report Share Posted August 28, 2008 If the car was sitting, maybe the voltage was low, and the battery has a deep cycle short. I would give it a few days to see if it clears up. As mentioned answer yes to clear the codes, and wait & see. As far as the fuel gauge acting up, we recently had a discussion on this. Add a bottle of Techron to the gas tank. I believe you can pick this up at wal-mart, or a chain auto store for under $5.00. it'll clean the compounds off the fuel sensor in the tank, and at least you'll have an accurate reading. - A suggestion Many others on this board will be more willing to help you if you change your screen name. we are here to guide you before you take your car to a shop where they may try to rip you off, or direct you in a way to save you some $$. Also, these cars like to be driven hard. Drive it like that every once in a while. Good luck. Link to comment Share on other sites More sharing options...

Hi, after I let it sit, the battery was dead and I had to buy a whole new battery because my 2 year warranty was just up on it. I will get the Techron also. Oh, I will change my name because I surely need the help and advice. Thanks, Angela Link to comment Share on other sites More sharing options...

I agree with Jims_97_ETC. Check the wires going to the transmission. ASSUMING that your oil filter really WAS loose... the wires may be covered in oil and causing the SERVICE TRANSMISSION problem. It is possible that they just need a good cleaning and be plugged in again. Link to comment Share on other sites More sharing options...

BodybyFisher Posted August 28, 2008 Report Share Posted August 28, 2008 The P0717, is a big job to fix. The ISS speed sensor in the tranny is bad, it took me a month last year and I did a bunch of other stuff. Cadillac wanted $1500 to fix mine, and they were reluctant and would rather have rebuilt the tranny. I doubt that cleaning the plug will fix the P0717 code, that is the optimistic approach, but its the sensor. This is not a good car for you, if you are not doing the work yourself. Look, at the name you choose. Get it running and sell it, its not for you. Being a 96, problem after problem will crop up, if you don't do the work yourself, you are going to get bled. The car is too old for you to take it to get it repaired all the time. These are great cars for do it yourselfers, they are complicated cars, if you need to take that car in for repairs, forget it. I know that sounds negative, but I am just being realistic and reacting to the name you chose, you are already disgusted.

Cadillac Jim Posted August 28, 2008 Report Share Posted August 28, 2008 The way to reset codes is explained on our how-to page: http://www.caddyinfo.com/readingcodes.html Basically, when it gets to the "PCM?" prompt, it is waiting for input. The inputs are though the A/C FAN rocker, with Up for Yes and Down for No. Select Yes, then No until you get the prompt "Reset codes?" and then select Yes. This clears the PCM codes. You clear them the same way; when you see the"PCM?" code you select No and repeat until the three-letter acronym comes up for the module you want to clear, then select Yes... -- 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.

BodybyFisher Posted August 28, 2008 Report Share Posted August 28, 2008 Angela sent me this PM, I think its pertinent to this thread angela: good gravy it is not that serious!!! You men take thing worse than women. It is just a screen name. No harm meant seriously but everyone has been telling me to sell it. It is so beautiful and I have already put so much money in it. I would hate to sell it, buy something else and have to put money in that all over again. Thanks for your input though. Angela My response: Its not a man or woman thing for me, I would have said the same to a man who is not mechanically inclined and needed to take it in for repairs. I have been a mechanic for 45 years. I personally own a 96 and constantly repair this car. Older cars need LOTS of work, period. If you are not mechanically inclined and do your own work, male or female, its best to buy a new car as the repairs will KILL you... with any car Yes its beautiful, but YOU not I said, "NEVER BUY A CADDY"......., if you look at the top of this page we are ENTHUSIASTS, we KNOW they need repairs. I am just trying to make you realize its NOT that its a CADDY its that its a 96, and you will need repairs on an increasing schedule.. An older car is ONLY good if you do your own work. Let me know if I can help, I have a 96 service manual.

Cadillac Jim Posted August 28, 2008 Report Share Posted August 28, 2008 P0717 Input Speed Sensor Circuit Low Input If this code is current then you have a shorted or disconnected transmission cable to the ISS. "Low Circuit" usually means shorted to ground but almost as often means disconnected. In any case, "Current" means that it was detected at the last check, which was since the car was last started. If this happened at an oil change, then it most likely is the wiring and happened as an inadvertent result of that work. -- 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.

Ranger Posted August 28, 2008 Report Share Posted August 28, 2008 Jim, while anything is possible, there are no trans connectors or wires anywhere near the oil drain or the oil filter. I can't imagine how it could have been disturbed. I'm a bit leary of that scenario. Link to comment Share on other sites More sharing options...
