Anti-Skid Temporarily Turned Off

nembilongmikelly · Mar 26, 2023

Hey guys, new to the forum here. I have a 2005 XC-90 2.5T with 200,255 miles on it. Bought it a couple of years ago and the previous owners took pretty good care of it. I don't have the service records as they were not passed on to me, but apparently there was a stack of them and I'm guessing that these guys took it to the dealer for service.

This past December I had a great deal of trouble getting any traction in slippery road conditions. After a bit of investigation I found that the AWD was not functioning correctly. I decided to take it into the dealer. I'm pretty mechanically inclined but decided not to spend the time on this one, plus I was a little nervous to perform this procedure.

I dropped the car off in mid January and they diagnosed it as a stripped out bevel gear. We went ahead and had them replace the bevel gear but when I picked up the car an ABS/Anti-Skid light appeared within a few minutes of driving. I have never had any sort of ABS light on the dash previously. I turned around and dropped it right back off at the dealer. The dealer was not super helpful, said it was unrelated, checked the sensors, cleared the codes, drove it around and said it didn't come back on. I drove back to the dealer, and the minute I turned the key I got "ABS/Anti-Skid Service Required". By this point I've had my Volvo at the dealership for 2 months and I'm super frustrated. I drove it away and figured I would sort it out the next week.

My climate control panel was also on the fritz, and I ended up replacing it yesterday with a junkyard unit. I wondered if the control panel was related to the ABS unit because the DTSC button is on that panel. No change after replacing the panel.

"Anti-Skid Service Temporarily Turned Off" has been on the message screen in this process. Currently I have:

"ABS/Anti Skid Service Required" & "Brake Assist Service Required"

Any thoughts on what would cause this and what I can do to resolve? I've done a good bit of YouTube research but wanted to reach out to this forum. Thanks guys!

Did they tell you what the code was when they cleared it? Finding someone local with VIDA would help alot, which is Volvos diag tool. It would show you which sensor is throwing the code.

I agree VIDA would help you with the first issue, but the CCM with dstc button may be the culprit of the brake assist service required message. You need a bcm that matches the setup of the car. If your car didn’t have Dstc before then putting in a matching but working ccm could resolve the issue. What was wrong with the Fritzy ccm? Still have it? If the knobs weren’t responding maybe pickup some contact spray and try that after a douse and spinning the knobs to clean the internal connections in the potentiometers.

Does you AWD work now? The angle gear input shaft goes into the trans collar sleeve of the 1st 3 pictures.
This is a dry non lubricated connection. Over time moisture will develop in the splines and start to rust.
As the rust builds up it becomes sand paper dust. Every time that the momentum changes, the splined sleeve
teeth will wear. The teeth edges are square cut. Eventually the teeth edges will be worn down to sharp edges.
The angle gear will start to slip inside of the angle gear sleeve pressed into the transmission and you now have
FWD only. Check your receipt and see if they replace the angle gear sleeve. If not, it should be replaced.
I have replaced the angle gear sleeve only and the AWD worked again with very worn angle gear teeth.
The angle gear is around $1800 for the part and the customer wanted to try the sleeve first.
As mentioned, you need to read the ABS code. The steering angle sensor can set this code.
As crap happens, it could be bad timing that the ABS code turned on and nothing that they did.

Angle-gear Sleeve is a flawed design.
This was why I simply install snow tires on my 2005 XC90 2.5T and done with.
My car (factory AWD) is essentially FWD.

The anti-skid message, search forum. I elected not to fix it.
Not worth it in my opinion.

Add some visuals to go along with the detailed description above Angle gear fail, 2008 XC90 V8 Sport, 050716, 100k miles

ChitownV · Mar 26, 2023

The pictures look good, but I would be more concerned if you can hear any grinding noises indicating the angle gear sleeve is slipping. If it was slipping before, then you shouldn’t have had weird slipping issues in inclement weather as the XC90 has open diffs, and as mentioned, you would be diving as FWD.

The very first thing is to check is the code. If you do a search on this forum, anti-skid could be a number of things, including a cheap fix: cleaning a dirty ABS sensor, medium cost fix: steering (wheel) angle sensor, to a more expensive fix: replacing the rear Haldex AWD module. As well as other parts as the traction is connected to, one example are the brakes.

Sometimes a dealership tech or service advisor are not willing to re-look at it since it’s a “return job” diagnosis they don’t get paid for. It happens. If you also search, often times dealerships don’t even want to work on the older XC90. Maybe they were willing to do it for a big job, but the tech had a difficult time because as mentioned how there can be rust, the sleeve was a bear to remove. Perhaps you didn’t need the angle gear to begin with.

I’d at least ask for the code at the dealership and if they say the light is out when they drive it, ask to ride shotgun next time they test drive it. If you aren’t willing to go back, then search how to set-up VIDA so you can check the Volvo specific codes.

The Anti-skid service required message can be caused by a number of things, and DFrantz is right about determining which fault has triggered the warning. The "Anti-skid turned temporarily off" appears, in my experience after the fault causing the "Anti-skid service required" message no longer appears. It can be helpful to pay close attention to other factors when these messages appear.
For example; when I turn into a perpendicular parking spot turning to the right, I will get the "Anti-skid service required" IF I've left the steering wheel turned to the right. When this happens, I drive a short distance away and stop the car with the wheels straight ahead, turn off the ignition, and restart after 30 seconds or so. Then when I restart, the "Anti-skid turned temporarily off" message is there, and then turns off after a short drive. There are no fault icons in the DIM, as the fault self re-sets. Maybe

.
When I first bought my XC, I had the "Anti-skid service required" message appear randomly, so I bought a steering angle sensor at the junk yard, as that was what all the discussions were about, at the time. That had no effect, so I got VIDA up and running and discovered the fault pertained to the "Brake vacuum motor" and found nothing on that until I came across a post about the ABS motor on the ABS block having the brushes worn out. Went to the junk yard and harvested a motor from a later S60 and swapped it into my XC90. Problem solved, until the right turn parking thing showed up years later.

As already stated....Codes drive everything. In general the ABS/Anti skid system is not very problematic with the P2 platform. That being said...It can be a bear to properly diagnose without all the information. XC90's used ABS sensors, YAW sensor and steering angle sensor (SAS) to determine IF a skid was probable. To replace your bevel gear sleeve the right front axel would need to be removed. So if there was no ABS issue before, it could just be the right front sensor has a connection issue or has failed. A lot of pounding on stuff to dis-assemble can result in unexpected issues. As several people have recommended... I would have the vehicle re-scanned for codes and if at the Dealer, can they tell you the freeze frame information. I.E. did the vehicle see the issue at idle or at XX-MPH. It would help just to know all conditions the vehicle is under when the codes are generated.

I mean... if it fails every 10-15 years, that's really not a failed design.. just not built for robust forever use. Fixing once now will probably last the rest of the life of most of these cars.

vince1 · Mar 27, 2023

Ditto what capndirk says on the symptoms. AWD is intermittent on ours and I think it corresponding to where the steering wheel is pointing.
It has been diagnosed as having a faulty steering angle sensor. I've bought another, just haven't had time to install it yet. BTW Canadian customers don't buy from FCP euro because they insist on using UPS and you will get ripped off on duty ($87 in my case).

cphvolv · Mar 27, 2023

I agree with DFrantz..........not a design flaw...more of a "designed" sacrificial part. Better to tear up a Bevel Gear coupler that the output shaft of the transmission or the Bevel gear itself. And after a good nights rest I'm inclined to recommend inspection to the tone ring on the right side axel. 2005 XC90....I've seen my share of rusted and broken tone rings that will give intermittent incorrect information.

No, they didn't tell me what code it is. I'm an hour away from the dealer so I'll probably see if I can get a guy locally that has VIDA.

The main issue with the CCM is the defroster would cut out intermittently. Not great in Wisconsin winters.

Good idea on the contact spray. I did install a used CCM from the junkyard but one of the controls seems to be sticky on that one.

I like it.

Thanks for all the info guys, I've got a lot to work with now! She runs and drives so it might be a few weeks before I make some progress on this.

Mine never failed, so I haven't seen it first hand, but I seem to recall someone posting pictures of a stripped coupler and a damaged spline to go with it. Could be wrong, though...

ggleavitt · Mar 29, 2023

See post #6. Rumor had it that the AW5 sleeve would strip before the input shaft, with the TF-80 the sleeve was hardened so both components fail. Photos are a good example of the combined wear. Still have a spare new "exchange" gear on a shelf in my garage for the Ocean Race someday. Agree fully with the previous posts, in my case it was wet rust when the Sport failed (as noted in the photos). Sleeve kit used to come with grease, instruction in the box to use the whole tube in the sleeve to gear interface. Can only guess how it takes for the grease to dry up. The 5 cylinder I think you can do on the vehicle, for V8 subframe needs dropped.

Another very common cause of this particular code / message light is older batteries.

Again XC-90s' have that larger battery, that seems to last only 4 years,...max.

There are a lot of XC90 owners who have batteries that last between 5-8 years. Yeah, crazy. Search for batteries or battery size and you will see multiple people with that lifespan, including me. You are right though, a low voltage can cause phantom codes, in general, on any vehicle that uses computers.

IPD makes some replacement knobs for the CCM, but they don't list it for the XC90. Maybe call them or perhaps someone here can chime in who has replaced theirs. Or maybe you can replace the knobs from your original one if they aren't sticky.
