Car Forum / Volvo Cars / July 20051999 S80, Here we Go with Dashboard Errors - I owned it for a week now
I am seeing, usually first, an STC error, tells me to stop safely. Now is accompanied by the following messages: ABS Service Required STC Service Required Power Steering Service Required Emission Control Service Required Brake Failure, Stop ASAP I plug my ODBII scanner in and I get code P1633 (Manufacturer Aux Input/Outputs). I clear the code with the scanner, and all messages go away for awhile, sometimes a day. Sometimes an hour. Everything seems fine, no power loss or other problems. I understand this computer system uses a CANN system, somehow it multiplexes signals and sends them between the computer modules. Someone suggested that possibly one code could hit a trouble (like STC), and that the data buses can possibly flood themselves causing delays in communication with other sensors. The delays cause the computer to think other systems are down, causing the messages on the dashboard. I suspect a possible vaccuum leak on the brake booster, I hear a slight hiss - perhaps that is enough to throw the whole system out of whack. Since so many system seems involved, I also still suspect an alternator problem as well?!? Has anybody had the combination of problems? Not happy with my "new" S80s temper. Deacon Eisenhart i experienced a problem with a 98 s-90 i think it was had a burned ic chip on back side of speedo head unfortunately due to odometer tampering laws in us i was unable to purchase the ic chip to repair it myself ..just an idea to look at the dash is fairly easy to remove takes about 15 minutes i rebuild transmissions for a living and do automotive ecu repairs on the side at night...like i said not sure but could be a circuit malfunction on the backside of the dash since most main signals are sent thru the ic film on back of dash > I am seeing, usually first, an STC error, tells me to stop safely. > [quoted text clipped - 29 lines] > > Deacon Eisenhart > I am seeing, usually first, an STC error, tells me to stop safely. > [quoted text clipped - 5 lines] > Emission Control Service Required > Brake Failure, Stop ASAP Had all these errors when my ABS computer went south. Mucho £££ to fix. There is somebody who repairs them in the US but can't remember his name... Welcome to the '99 S80 owners club.

The services offered looks like an alternative if this is what you need. hummm...interesting web site and volvo info...thanx for the url........ http://home.earthlink.net/~vicrocha/ When I bought the car, I bought a 2 year unlimited mile warranty. I hope it all works out and the problems that need fixed are fixed. Thank you for the link, I did come across that before and bookmarked it. It seems like the Volvo computer is useless technology if one code triggers another. My car tells me power steering is failed. Why? I'll know when it fails when it doesn't work anymore. I really hope that somewhere out there, beyond this newgroup, there are people happily driving these cars without any problems. I bought a great christmas CD that I am going to play when things start lighting up. Maybe it'll help me cope.

[quoted text clipped - 45 lines] > > > > Deacon Eisenhart When there's a problem with the ABS computer, often the errors involve a problem with the computer reading the wheel sensors. This will then generate an error in all the systems that use wheel speed info, as the ABS computer is the one that reports this info onto the network. This would account for the STC message, and maybe the power steering message, if you have speed sensitive power steering. The brake booster leak is a fairly common problem on those cars as well. The "Emission Control Service Required" message it the equivalent of the check engine light, the code for that will be readable with a generic OBD-II scan tool.  SignatureMike F.

OBDII code P1633 = Volvo Code ECM-510F = Speed signal missing It would seem that the ABS ECU is failing or there is a problem with the CAN Bus. 1. Does anyone having any idea how credible this source for ABS/STC module repair is? http://home.earthlink.net/~vicrocha/Volvo_Parts/Volvo_ABS_FAQ.htm#HowLong 2. I have not had any errors from the car today. I have an appointment with the Volvo Dealer down the road in about a week, but I'm afraid that if I cannot keep an error on the system, they may not be able to confirm a module failure - or any problem at all. It seems like the braking messages are being erased when the car is restarted. 3. I don't know why this is, but if I turn off the STC system, where I get the warning light the system is disabled, usually within an engine restart or later in the drive the car will show all of the previous aforementioned codes. 4. Is there any place I can get a code translator or a computer scan tool for reading the special Volvo codes? Deacon >>> When I bought the car, I bought a 2 year unlimited mile warranty. I >>> hope it [quoted text clipped - 70 lines] > It would seem that the ABS ECU is failing or there is a problem with the > CAN Bus. I do not know anything about this specific repair place. (Thanks for finding it and postint the site) I know of another repair place just starting to repair ABS control units. I know of 3 ABS brains that have been repaired and they are working ok. The repair shop that I know about charges $180 to repair the ABS brain. The repair place that you mentioned sounds like alot better deal. I would not have any trouble sending them my ABS brain if (when) it fails. If I remember right, a new ABS brain is around $300 to $400 US dollars. Some repair shops and dealerships charge 1.5 hours to read codes and replace the ABS brain. At $80 per hour that is at least $120 labor alone. Follow the instructions, take your time and you can remove and install the brain yourself. BD ------------------------- > 1.

In addition, $75 per hour. I bought the E5 Torx socket from ebay to remove it from the ABS pumping mechanism. It sounds like these ABS repair shops are putting bigger current handling/heat dissipative components on the board inside the controller. The failure DOES seem to be heat/weather related. Humid warm days with rain tend to throw mine into errors whereas a nice cool day everything is fine.

No personal experience, but there's been nothing but good thing said about him on the brickboard. http://www.brickboard.com/ 2. Don't worry, codes are stored for quite a while, even after the lights go out 4. There is, but you need a laptop computer and big bux. https://www.volvotechinfo.com/ as far as I know, there's no aftermarket reader that will do everything. SignatureMike F. Thornhill (near Toronto), Ont. Replace tt with t (twice!) and remove parentheses to email me directly. (But I check the newsgroup more often than this email address.) My errors on my 99 S80 ( 80,000 miles) were limited to "Emission Service Required" and "Check Engine", and it took 3 trips to the dealer to finally resolve it. 1st trip - 2 Oxygen Sensors at over 200$ US ea., plus labor = 900.00 2nd trip - Reset computer, lights came back on in about 100 miles. 3rd trip - 2 more Oxygen sensors, another 800.00 incl. labor. Total was over 1700.00, and now all four sensors (2 forward, 2 rear) replaced. I just wonder if all 4 were actually bad, seems like quite a coincidence to me, especially since sensors have no moving parts, all decided to crap out at once.....Must have had some real dirty air moving accross them babies! Fortunately I had an extended warranty, so out of pocket expenses were only 150.00 Had I not, I think I probably would have removed all the warning lights from the vehicle after the first repair bill. Can't wait for the rest of the electronic miseries to occur. Truth is, though, this is a great car otherwise; I really love it. Of course I love my 89 780 too, and I'm just now begining to throw large chunks of cash into it....but at least it's not quite as finicky as the newer models! Good luck to you. >I am seeing, usually first, an STC error, tells me to stop safely. > [quoted text clipped - 29 lines] > >Deacon Eisenhart > My errors on my 99 S80 ( 80,000 miles) were limited to "Emission > Service Required" and "Check Engine", and it took 3 trips to the [quoted text clipped - 3 lines] > 2nd trip - Reset computer, lights came back on in about 100 miles. > 3rd trip - 2 more Oxygen sensors, another 800.00 incl. labor. My bet is that the wrong sensors were replaced on trip 1. There was probably only one actually failed sensor and it was probably one of the two replaced at the 3rd trip. No one will ever know for sure because the parts are probably all in the trash already.

Where are they located? INSIDE the Transmission? $500 labor to replace two O2 sensors!? The 240 I am looking at is starting to look REALLY nice! With the 4 sensors, you just spent about as much as I might on a very nice 240 I am looking at! Phewwww- I was told when I was young that buying quality tools was a good investment...

Did you purchase this from a Volvo Dealer ? & if so why was it not repaired free of charge to you ? I do not know what dealership performed this repair but I find that you are correct there is no excuse for the shoddy Diagnose & repair of your Vehicle this type of repair give all Volvo technicians a bad name do not think that all of us are clueless when it comes to correctly repairing your car right the first time G Klein Volvo Master Technician ASE Certified Technician Signature"*-344-*Never Forgotten" Is for the New York City Firemen who lost their lives on September 11,2001. The official count is 343, but there was also a volunteer who lost his life aiding in the initial rescue efforts. And I will never forget them as long as I live, nor should any American. True, without actually seeing the defective sensors, I am at the mercy of the dealer techs. In any case, it's pretty scary that the repairs could cost this much. Having no way to diagnose this myself, I didn't have much of a choice, and 3 trips really wore me out, I just wanted the problem solved once and for all. >> My errors on my 99 S80 ( 80,000 miles) were limited to "Emission >> Service Required" and "Check Engine", and it took 3 trips to the [quoted text clipped - 71 lines] >Volvo Master Technician >ASE Certified Technician |
