ABS C1095 Hydraulic Pump Motor Circuit Failure

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.

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)

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.

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

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.

Planning to get there. What with one thing and another not been on the site for a couple of months - missed out on the sticker, takes ages trying to catch up with a few days posts let alone months.

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  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 ?

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.

So i can crack all external surrounding without fear because there is also an internal fixation of the cap ?

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.

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

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.

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.
