Brake failure and engine warning lights after carwash

Post by **tailor** » 15 Jul 2011, 08:17

Hello to all

I have the above warning lights that came on when I left the touchless car wash. The temp gauge has also gone to zero, as well as the vehicle being in limp mode. I am hopeful that it is a temporary issue and it will resolve itself......... I tried turning th car off and restarting no improvement. All the fluids in the brake cylinder and water are full. Would a battery disconnect help?

Anybody have some good ideas,my thinking that something may have been dislodged or BCM gone on the frits.....nothing on the site appears to give any tips...

sounds like you have water in the cem pull wipers and cowel off on drivers side remove the cover and most likley when you pull the top plugs out you will find water in them there is a updated cover to prevent this from happining good luck

Well a sort of update, I disconnected the battery and that cleared the codes except the "anti skid service required" code, All went well for the first 100Km of a 250KM trip, then ABS, engine and oil lights came on, the speedo , tach and temp gauge all went to zero and would bounce back up and down. The Abs and the check engine light did the same thing, the oil light would be on occasionally as well. Another symptom was the A/C would shut down. The odd thing is that when I stopped to gas up, the lights stayed off for a while, and then the same pattern ensued. I also experienced a limp mode scenario. I have a Inovo 3100 which reset the Abs and other error lights and would solve the issue of the limp mode as well, the remaining light on is the Anti skid. I disconnected the battery again for 45 minutes while I had the wiper cowel off to check for obvious signs of water, none was found, but still no joy in resetting the anti skid. I took the car for a spin and so far so good no other error lights and the scanner shows no errors either. This has got to be the result of water causing a short circuit. I gave a good spritz of contact cleaner and cleaned all the grounds I could find, perhaps a little too late but I am grasping at anything to solve the issues I had/have.
I fear that the dealer is the only one able to reset the anti skid, am I right?
Any further input would be very welcome.

I own a 2004 XC 90 T6 as well as had similar thing happened to me except that I didn't go to the car wash. My wife was returning from work and noticed the vehicle jerking. A message came on the dash board stating "Brake Failure. Stop Safely". The lights on the dashboard went off and the speedometer went to zero. The engine was still on, but the windows could not go up.

I took the vehicle to work the next day and similar thing happened. When the engine is cool, it doesn't happen, but aftr driving the vehicle for 20-30 minutes, this message appears and when attempting to restart the engine, the "Check Engine" light comes on. After a while, the light goes off. When attempting to restart the vehicle, you hear a clicking sound on the dashboard and after a while, the engine comes on, and the brake light indicator goes off at times.

Could this be a problem with the ABS Module or the Sims Module. Please share your thoughts if you had this problem before or know of someone who experience similar problem.

Sounds like an ignition switch issue (electrical portion of switch). It's known to do the weird stuff you describe above.

I have just completed a 500 km trip and the only error lights still on is the Anti skid service light, everything else is working well. I will go to my trusted mechanic when I back in town. It is not the ignition switch.
Thanks you for your thoughts and input.

I hit a huge puddle and it stalled the car and made the dash light up like a Christmas tree. The engine was coasting an that was the problem.

A little more on the Saga....
Just to let you know the %$5%$54% sunroof drains where blocked and I had water cascading into the vehicle, after a rather recent hard downpour, on the steering wheel, radio, centre console etc.etc. The chaos that ensued was horn going off by itself the climate control unit jumped from one mode to the other..... in short(no pun intended) a nightmare.

My local "indy" checked the codes for me, (and cleared them) as many and as long as "War and Peace" ( artistic licence)
BCM SET ,SAS SET, SRS READY, TCM CHECKING, ECM SET, DEM NOT CHECKING, CEM SET, DIM READY, DDM SET, CCM SET, PDM SET, PSM CHECKING,ICM SET, REM CHECKING, SWN SET,UEM SET. Btw they are all back.
If you go to the section here,
https://www.matthewsvolvosite.com/downlo ... iagram.pdf you will find the definition of these codes, thank you MVS
These codes can also be obtained by simultaneously pressing the read button on the stalk and the rear fog light button twice(quickly), Press read to scroll through codes. Just so you know, they cannot be cleared other than by dealer or some code readers.
I decided to check underneath the front carpet and found that there was still some water, I removed the carpets and let them dry as the foam was saturated. In discussing the issue with of the "indy " they suggested that I should do a little more probing, "maybe its a blown fuse" . Upon checking all the fuses,in front, and rear I found that fuse # 17 in the rear,was blown, I replaced it and it blew again immediately. This fuse is for the All wheel drive control module, DEM( Differential Electronic Module), this module is in the rear of the car under the 2nd row of seats, I believe this is the problem "child" Once I get the fuse tester in hand I will trace the issue down, it
may also just be a short in this wire harness. If not I will remove the DEM and send it to BBA Canada to check: http://www.bba-reman.com/ca/index.aspx, as there counter part in the UK seemed to solve the issue. See post below:

There is another post it makes really interesting reading :

I do not have a definitive answer to the problem, but I am always hopeful that some smarter people than me will be able to offer some enlightenment. I certainly feel that I am grasping at straws at this stage.
Feel free to chime in!

More to come , no doubt.
