Title: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 20th, 2007, 2:16pm Hi Both the Teves 20 controllers I have suffered from intermittent ABS light staying on until total failure with code: C1095 Hydraulic Pump Motor Circuit Failure. I broke one controller open & found bad solder joints on the pins to the pump motor plug, I re-soldered them & it works fine. So thought I’d just drill a hole in the other unit above the pins (22mm hole saw with no pilot - best done in a pillar drill so you don't go too deep), sure enough same fault, this one’s now working. I think the problem is that although the board seems firm enough it’s held in place with mastic, whereas the pins are fixed in the case so over time vibration causes the joints to fail. Check out everything else first as this code is fairly loose - just taking out one of the ABS fuses (can’t remember which) will produce it. http://i.imgur.com/EJsTlBb.jpg A bigger picture here: Here (http://i.imgur.com/loEraJM.jpg) Dave |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 20th, 2007, 2:45pm WOW that's brake through info !! There was also a problem with pin 2 which server the module with 12 V. Somewhere the power supply get interrupted. Running a separate wire to pin 2 also cures the problem (if necessarily) |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 20th, 2007, 3:24pm scorpio_man OK I'll save some higher res jpg's (they're in Corel Draw at the moment) - not great quality as they're done on a scanner. Octavian_P Talking of pins these connect (pin 8 in the main plug Teves20) via the circuit board, on mine if I pushed the pin sideways (for the motor) with the test meter probe I could get it to make & break contact http://i.imgur.com/L9kdsFX.jpg |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 20th, 2007, 3:38pm That's very good info. I'll test on my spare ABS pump / controller which i bought and gave me the same trouble >:( When i was referring to pin 2 i meant the power supply. That also causes the 1095 code in some cases. |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 21st, 2007, 8:38am How can i open the module. I have took it off the pump (4 star screws) and now i have the black box apart. The problem is that i can not take the cap of. Is it glued ? i don't want to crack it open ;D I have tried with a screwdriver but the plastic tends to crack where i force it. Does it got some good levering points or some clips ? |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 21st, 2007, 10:40am Afraid it doesn’t come apart easily, which is why I drilled a hole in the second unit – in the hope it was the same (maybe common) fault. First you need to get the locking washers off that go under the mounting screws, push something pointed into each hole in the washer in turn and lever it up. I used an old pair of pointed tweezers, maybe a dart would do. It’s well & truly glued on with some sort of mastic. There’s a channel all around the base that the cover is glued into. I had to break the plastic all around the base then gradually lever it off with a wide blade. Looks a bit of a mess but you should still have the inner part of the channel left on the base and the lip left on the cover so a decent mastic should still be able to seal it. The board is covered in soft clear mastic which you have to remove around the pins to inspect the solder but it scrapes off easily with something soft like a matchstick. If drilling a hole just make sure you don’t go too far, a pillar drill with a depth stop would be best, that way you can use a hole-saw without using the pilot drill. I used a 22mm hole-saw as it was the largest I had that would stay on the flat surface in the corner of the cover over the pins – keeping on the flat makes it easier to glue something over the hole. Hope it’s not given anyone false hopes. I thought if enough people had old dead units they could drill into we could see if it is a common fault. I could have a look at a couple of controllers if anyone wants to send me an old unit with this error code. Dave |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 21st, 2007, 10:45am So i can crack all external surrounding without fear because there is also an internal fixation of the cap ? |
||
|
Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 21st, 2007, 11:07am Yes, you'll be left with a single overlap instead of a tongue in a channel - assuming the glue on the inner edge is no stronger than mine was. Give me 10 minutes or so & I'll see if I can send a picture, a bit tricky getting detail in black on the scanner. |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 21st, 2007, 11:26am Thank you one thousand times, i have just opened mine :) Measured from outside it didn't have continuity. Now after some hammering and screw action it has... it'll just re solder the joints and try it on the car as it is, without mounting it on the pump. Fingers crossed. Well if it doesn't work i have another one on the car to start with, especially that i know that the 1095 was intermittent ::) |
||
|
Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 21st, 2007, 11:41am Great, hope it works :). I used a small pin vice to clean the pins (like a small drill chuck on a handle) - tighten it very-lightly onto the pin & revolve it whilst pushing. This removed the plating and some of the solder & meant the fresh solder went right up the pin. By the way I didn't need to clear the code, the light went out straight away. Don't do the screws up too tight, one of mine chewed up & wouldn't come out - fortunately a top one so I managed to drill through it. |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 21st, 2007, 1:58pm OK i had to stop testing, i'm soaking wet, it's raining cats and dogs outside. I have tried the "refurbished" module without actually connecting it to the whole assembly, i just have connected the multi plug and the 2 wires coming from the pump. The light is still on. I havent got the strength to measure if pin 2 gets voltage. Anyway, now the module on the car will be subjected to the same treatment especially now that i know it did work intermittently. |
||
|
Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 21st, 2007, 2:26pm Might clear when you drive, but I didn't have to. I did just check by plugging in both plugs on my spare unit without fitting it to the ABS block, & can confirm the light stayed off. |
||
|
Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 21st, 2007, 2:55pm Anyway what is interesting is that even if the module still doesn't work it did have the solder problem. Before opening it didn't have connection between (the two pins). After fiddling with it and resold it's OK from electrical point of view. I'll try some parts on it like diodes, and resistors using my trusty multimeter. Maybe we'll find even more "strange" ABS "happenings". |
||
|
Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 21st, 2007, 4:08pm I noticed a few areas where the clear mastic coat (assuming your's has this) was cloudy, underneath there was minor corrosion or residue from the solder. |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 22nd, 2007, 8:27pm I'm back with news. Today i had a bit of time to do a quick check on the module mounted on the car. Well i measured and theres no continuity as is should be. So from the start the problem repeats. So in two modulator i have they both have the same problem. Now all i have to do is to take it off the car and do some "brain surgery" to it. I even tried today to get it off...got 3 screws form 4 but the last one has rounded and could not get it of. I tried to saw it's head in 2 pieces and then use a big flat screw driver....but the blasted split and broke. Not it's half headless. I need to take the expansion tank out and somehow saw it from underneath. |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 23rd, 2007, 12:28am What a pain, I shall try & get some allen screws for mine. I drilled a 4mm hole sideways into it to break the screw - as in the picture, but that was on the top, I doubt you can do it on the bottom screws. http://i.imgur.com/51yGiuI.jpg |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 26th, 2007, 6:51am Hi there Finally i had a bit of time to take a second turn on this matters. I managed to saw of the screw after taking out the expansion tank. After opening the module at first look it seemed to be ok, but the multi tester measurement was telling something else. Alright i have removed the rubbery coating (i think it's silicone based), and look at the soldering points with a magnifier glass. Both terminals where cracked and unsoldered from the PCB. Took my trusty solder iron and soldered them back for good. After this i went to the car. Plug in the wiring, put the keys on....the abs light extinguishes after a second or 2 ... ALRIGHT ;D Went back in the house, and sealed the unit back with tons of silicone ;D. Went back to the car screwed back the module on the pump, i have connected the wiring and took the car for a test drive. Went all the way up to 50 mph, the light doesn't come on..., then at a more gentle speed i slammed the brakes on a mudy and wet piece of tarmac. The ABS came on, pump was wiring, and i could hear the brakes blocking - unblocking making thumping noises. In other conclusion now my ABS after more than 2 years of ownership it's finally working again. Thank you once again DAVE (Tompion) for sharing this. |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by petehull on Mar 26th, 2007, 9:05am :D Hey.. isn't this what this site is all about, this is brilliant fault investigation work, just shows it doesn't have to be a juck away world. I have had many instances of this type of repair work, I used to runn a (believe it or not,,, WARTBURG I had the car for 13 years during which time i carried out a partial rebuild and then later a last nut and bolt rebuild. I found I was having to repair bit ie POINTS of all things when I couldn't get them, switches, distributer etc etc unfortunately I was given a company car for 3 years during which time the Wartburg was stored in my garage, when I got it out again it was in such a state I couldn't be bothered to continue with it so I cut it up and scrapped it.... Oh well Anyway Very well done and keep the good work going.... Pete |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 26th, 2007, 10:25am Octavian That’s great news :D That’s exactly what happened to me it looked fine, but on close inspection with an eye glass I thought the pins looked a bit suspicious, once the shiny silicon was removed it was obviously bad. So between us we’ve had 4 units apart, all had the fault & 3 have been made to work by soldering the same pins. Still too early to say, but starting to look like a common fault. Also interesting that you didn't have to clear the fault code either. Not sure if you have an ABS test lead. Did you check for any other fault codes on your other module? I’ve just done a test on mine, I disconnected one of the back wheel sensors & drove it up to 30mph. After turning off the ignition & reconnecting the sensor the light stayed on but went out at about 15mph. Might be worth plugging the other unit in and tying it up somewhere and seeing if it clears when you drive. Dave |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 26th, 2007, 1:23pm In a week or two i'll meet with a friend who has an OBD-2 Cable compatible with ISO standard, so in other words it reads the ABS Codes as well. I'll take the "non-working" unit with me and see what codes does it bring and if they can be erased ;). Now i have a puzzling problem with my cossie. It has ABS + TCS and the 1095 code came a few times beside a rear wheel sensor which is always failing :P |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 26th, 2007, 2:28pm Does your cossie have the Teves Mk IV? I’ve not looked at one of those & wouldn’t be able to test one anyway, but if anyone has one with a known 1095 code they don’t mind sacrificing I could break it open & look for a similar problem. |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on Mar 26th, 2007, 2:38pm to be sincere i don't know how what model it is. It looks like this http://i35.photobucket.com/albums/d190/Octavian_P/untitled.jpg I think it's the same model as HERE (http://www.fordscorpio.co.uk/absmodulator.htm) But the pump plug still remains http://www.fordscorpio.co.uk/images/absimage17.jpg |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by jmdickinson on Mar 30th, 2007, 3:42pm I have a Teves IV and did the repair this week by drilling the case. This one is plastic as against what appears to be aluminium on those shown. So far the fault seems to be cured. I've had permanent C1095 for a while now although it started off as intermittent. It seemed to clear on one occasion after cleaning the motor plug connector but now I understand why if it was a bad connection inside the controller, :-* which I probably disturbed when disconnecting the plug. I have a '96 24 valve, the part number on the controller is 95GB 2C013 BB and when I contacted BBA they said they didn't do exchange units for these but could do a repair for £175 depending on condition. So many thanks for an excellent tip, maybe I'll be able to get my 42" plasma T.V now. :) |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on Mar 31st, 2007, 10:46pm I suspect the Teves IV is a lot more common than the Teves 20, so this is an interesting development. The case on mine is also plastic, but I played with the pictures a bit as the detail of the black case tended to get lost. Enjoy your telly. :) Dave |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by caspathescorp on May 1st, 2007, 9:00pm You can add me to the list of repaired abs pump fault. my abs light was on giving me code C1095. I have drilled my one today ,resoldered the pins, refitted the pump and drove around. the abs light went off as soon as i started the car and stayed off. I will test my other pump later this week to see if that is the same. It seems like there is some common fault to all these pumps. My one is the Teves 20. the letters start with 97 GG. Thanks for the advice everyone. Caspathescorp |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Tompion on May 2nd, 2007, 9:06pm Caspathescorp Glad you sorted it. Let us know how you get on with the other unit, either way. I’ve found contrary to what is often said you don’t need to clear faults for the Teves 20 to work, although the fault codes remain in memory until cleared. Dave |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by sector-9 on May 28th, 2007, 1:09am Well I did my Teves IV on Saturday. Don't have a code reader for ABS so no idea what codes I was getting but thought I'd try it anyway. Solder joints didn't look bad, but they don't always so I resoldered them both anyway. Imagine my frustration when the light came on several times later that day (always went out when ignition cycled and >11mph), but it hasn't done it at all today and I've done nearly 200 miles in the rain... Thinking about it, it's likely I've got more than one fault - previously it would either a) ABS light wouldn't go out at all (except sometimes at >11mph) b) ABS operates below about 5mph even under normal braking; light often comes on shortly after. After resoldering the motor pins the light now always goes off after a few seconds, but I think one or more wheel sensors are duff because (b) still happens. Any idea how to find out which it is without a code reader or a trip to FMD? Darren |

Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on May 28th, 2007, 9:42am Hi there. it should be like this: 1) each sensor has a resistance of about 1100 ohm (or 1150 - can't remember exactly) 2) with the wheel suspended and rotating a slight voltage should appear between the pins of the sensor eg. 0.2 Volts (alternative current) 3) print out the schematics here http://www.carsoft.ru/avtorepair/sierra_el.html and look if all the sensors have continuity at the pump connector. 4) If all is ok from the electrical point of view, it could be that one sensor is dirty. The dirty sensor should produce a smaller voltage than the others. But a multimeter is not that precise. If you have access to an oscilloscope you could actually see the waveforms. |
||
|
Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by sector-9 on May 28th, 2007, 10:57am Thanks for that - I do have an 'scope but just couldn't be bothered to learn how to use it and the problem is so intermittent that I don't think I'd see it unless I was very lucky. Still, if a dirty sensor does output a lower voltage or a different waveform then that would be a valuable clue. Darren |
||
|
Title: Re: ABS C1095 Hydraulic Pump Motor Circuit Failure Post by Octavian_P on May 29th, 2007, 8:56am Also just remembered, you could check if the front hubs have the protective plastic caps. On my cossie i lost one, and the sensor and the ring were exposed and full of dirt |
