Winter 19 Posted February 3, 2009 Report Share Posted February 3, 2009 Does ABS somehow trip-out in excessively slippery conditions? Mine did yesterday and again today. After switching off the ignition, normal service was resumed. In icy conditions, ABS is near-lethal because there is little or braking effect so I was wondering if there was some sort of flogging-a-dead-horse-type override in the system. Alternatively, might the behind-the-hub sensors have been contaminated with snow and slush? Of course in the dry and especially wet conditions, ABS is superb but in snow and ice . . . well, that's another matter. Quote Link to post Share on other sites
Jukka 17 Posted February 3, 2009 Report Share Posted February 3, 2009 ABS works well in ice and snow. Much easier to drive with abs than without. You can steer when braking and so on. In dry conditions no need abs. Looks like you need strudded winter tyres also in UK. Quote Link to post Share on other sites
Günter 28 Posted February 5, 2009 Report Share Posted February 5, 2009 (edited) If you spin your rear wheels to much (with an full standstill in front, or with different rotation-numbers on the wheels) the ABS does sometimes think there is an implausible signal -and it set an code. That was also on my car, in the time as it was my only car that runs (as it was an full-season car). After work i used it regularly to have some fun in the wintertime on short runs across parking lots (or more realistic for 'drifting'). I think there is an note about "excessive" wheel spin in the ABS section of the workshop-book ... @Jukka: do you really have some sort of 'winter tyre' on both ends of your car ?? I think there is still no winter-profile type available in 235/40-17 across the www. tire-dealers :-/ Edited February 5, 2009 by G Quote ********************************************************************* to name the things if I see them, that's what I call integrity.. ********************************************************************* Link to post Share on other sites
Winter 19 Posted February 5, 2009 Author Report Share Posted February 5, 2009 Thanks Gunter. This ties in exactly with what was happening. I live and work in Sheffield, England, and like Rome, Sheffield is built on seven hills. Hills, snow and wide low-profile tyres are not the best of combinations. I spent much of Monday and Tuesday of this week with the rear wheels turning much more then the fronts - as you say, good fun - so the ABS ecu could, understandably, have produced a safety-produced error code. I'll look in my Brakes Supplement when I get home tonight. Incidentally, I enjoy your authoritative contributions. What is your background/training? Best wishes.

Jukka 17 Posted February 5, 2009 Report Share Posted February 5, 2009 Ok, something like that may happen when fronts are standing and rears are turning fast. @Gunther I don't have winter tyres in Esprit. It's not my daily car and I don't drive it on very slippery conditions. Quote Link to post Share on other sites
Günter 28 Posted February 5, 2009 Report Share Posted February 5, 2009 "..authoritative contributions..." WHAT!? OK, on the other side of the channel I'm more known for stupid posts -just ask jimmibondy prior to '92 ->the only thing i was allowed to work on is bicycles and toy cars from '92-'96 ->specialized training 'to chop heavy metal', and fix trucks & cars -or parts of an truck/car from '96-'05 ->now legalized work as an 'professional' (idiot) -still the same company and the same old type of work... . Only one interruption: '96/'97, my type of 'duty for the community' and guess what -as military truck service technician ...hurray :-/ '05 up till now -> automotive engineering student, so you can say I'm pretty much focused [or on the other hand 'totally onesided'] ;-) Quote ********************************************************************* to name the things if I see them, that's what I call integrity.. ********************************************************************* Link to post Share on other sites
