Had to do a rush job on 328 clutch, and a day out with new owner of one of our "ex race" 360 challenge cars, so have'nt touched it for a couple of days. I'd really like the full test procedure for the wiring diagnosis element of the TEVES system. I asked sydney for it but they sent the Bosch info so now I've got to beg and grovel all over again!! Malcolm, if you are able to fax this info from the manual, or if the manual is online anywhere...it's pages G40-60 or something apparently.... I'll give you the fax no. in a private email if you ask me to, but I wont do it if you're not allowed to!! |

Thanks again Malcolm very helpful. I worked at KHPC from 1987 to 1994. Then solo for a while until a 2 year sub-contract to DK engineering from 1998 to 2000. I've been in Melbourne since then, and started my own business in January this year after working at the race team for 3 years full time. I can't say I remember you, but I have spoken to many dealer guys over the years, so g'day anyway!

Phil Don't know if this will help but Teves are now called Continental Teves AG & Co OHG Aftermarket. There web address is www.conti-online.com might be worth a try MW |

Phil - sorry that's US dollars BTW Did you ever work with Ferrari in the UK, it's just your name's familiar - I've worked with Ferrari UK (or as it was known Maranello Concessionaires) for over thirty years, so maybe we've spoken before? Cheers MW |

Phil, Tom has a good point, there may be another manufacturer who will sell spare parts for the hydraulic unit, but we've tried before in the UK and no-one will supply parts separately. The trouble with a secondhand unit is as you know it could have faults of its own, however if you need a new unit we do have one in our warehouse costing $1800, MW |

Phil..If possiable get the part number off of the old unit. Try to get the non Ferrari number. Call up a supplier of these units maybe you can call Teves direct(don't know never tried) and find out if that unit is installed in any other car. I'm 99% sure it will be. I know G.M. Ford Cyrsler have all used a Teves unit at some point. BMW and Benz I beleive have their own systems. Maybe someother Euro car has the same unit and you could get it for half the price!! But then again, it won't come in the fancy yellow box.(oh well take the good with the bad I guess) |

Thanks Malcolm, for confirming. And JRV. I don't have SD1 or test procedure...that's what I'm trying to establish. No, Malcolm, I don't have a donor car either. But does anyone know where a spare Teves unit may be...??? How much for new one...??? I was curious to know if it's a fault anyone has experience of, and of course I know ferrari say "fit new"....but surely it can be repaired. Maybe not cost effectively in dealer eyes, but something somewhere must be available. If anyone knows how to do a wiring test...specifically, and not just a theory from the manual which is vague, I'd be very appreciative. Thanks again guys. Great feedback. |

Phil - sorry for delay in replying, I've had a chat with one of our Challenge Technicians and he's pretty sure that the fault is as indicated the rear return valve within the hydraulic unit. As long as you are happy that the line locker isn't having an adverse effect and that the limiting regulator is okay I would go for the hydraulic unit. Might be a good idea to check all the wiring from the ECU to the hydraulic unit just in case it's a poor connection. As the hydraulic unit is quite expensive, do you have a donor car you could do a swap with to proove the point before ordering a replacement unit? MW |

>>come on Malcom, I see you're out there...what about this one.....<< you can test the valves by running the system in test mode ....they make the typical clicking noise when powered and unpowered. |

Thanks JRV. The fault code means the rear return valve. Which I assume means the valve that controls the release and application of pressure to the rear brakes from within the ABS unit at the pedal box...but I dont know which part this is, how to test it, how to repair it or much about it at all really! I've checked all the wheel speed sensors. There was grease/dirt and un-even gaps on them etc,which I've fixed, but there was still no fault code relating to them so I'm only doing precautionary jobs there. |

Phil. the computer can only read the electrical parts of the system...therefore it would be one of the system valves in the front, if it's a valve problem. The best reference source for the ABS System and how to check & test w/values is the Porsche 993 WSM. The system is tested and bled w/key on & safety plug on pump removed, which runs the pump in manuel mode. The most common failure is a dirty/bad/loose wheel speed sensor... I would clean & test all the wheel speed sensors first and replace any that are not exactly within spec...and double check plugs & ground wires. HTH's It's likely it won't reset because it's picking up a fault as soon as you power it back up. |

How do you re-set fault codes. I thought simply leaving battery/ECU off would re-set, but with this car the problem keeps re-appearing even without any use, so I'm not sure if it knows the fault is there, or I simply have not reset it to clear?? |

JRV Thanks for input, but the return valve is part of the ABS unit at the pedal box, I'm led to believe. I think it's an internal component, with electrical activation..... My customer's car has two pressure limiting valves for rear brakes under the central floor, and two brake connector blocks to the rear subframe...one by where the handbrake cable should be (RHD), the other on the left with the clutch line. These are not valves, simply connector blocks, and I've just done a big belts etc service so all things have been re-bled and inspected along the way. Malcolm...can you shed any light?? Any other clued up dealer guys with info?? |

There is only one valve in the rear, the seperater that's DQ'd to pull the engine. Seems unlikely that could cause "no brakes". Is the line locker upstream or downstream of the seperator valve? |

1996 355CH, in road use. Equipped with the ATE Teves system. Apparently normal brake operation at normal road speeds but owner states lack of bite and dead pedal from 200-100kmh on track, then massive sudden bite. Age old problem from way back, been eternally frustrating. Car has after market engine management installed, but otherwise fairly standard, apart from a line locker installed in the rear brake line to act as handbrake when needed. I've tried the line locker and it seems to work. Even after battery and ECU disconnected for days and line locker NOT USED, fault code still appears. Fault code from ECU is 2.7, which means rear return valve. Which is this, how to test, repairable??? |
