DS3 abs fault

[Ds3]

Hello all. New to the forum.

I have a 2012 ds3 hdi and it’s got a few issues regarding the abs.

Now the fault comes up on the scanner as
‘Recycling pump fault ‘.

I’ve had the abs unit tester by ecu testing in derby who have said it is fine.
So I’ve tried to bleed the brakes and it won’t allow me to run the computerised bleed procedure. So I had a local auto spark specialist look at the wiring (they have Citroen diag ect ) and they confirmed the wiring ect to the abs is as it should be.
So back off the abs pump came again. And retested at ecu testing. Who confirm that the pump and electrics are as they should be.

So once I get it back and if it kicks me out of the computerised bleed procedure again (like it did first time). I’ve got a car with no brakes. But everything should be working.
It’s a real head scratcher. Anyone had this before ?
Ecu testing suggested it could be a blocked brake line. But all lines seem to run clear when the pressure bleeder is on.

Any help on the matter would be appreciated. Getting to the point I’m tempted to bypass the abs completely

There are some procedures that can't be performed of there are issues with the system.

Hi there. The only code that is in the abs system is

C1380- recycling pump fault. Not characterised - permanent fault.

Vin number is. : VF7**************[VIN obfuscated, can be read by forum staff]


Thanks for the reply.

Hmm, I was once told that an old school mechanic had figured out a brake issue, the fluid wasn't returning back
The reason was that one of the brake lines had clogged and was working as a non return valve. Might sound stupid but it may be worth a check

Thanks for the reply.

So this fault code specifies it's a lack of voltage to drive the pump. Don't overlook the indirect things like the electrical connections, the pins and the wires. Check the plugs for cleanliness and use electrical contact cleaner to clean them up where necessary - at BOTH ends of the connections. Check the pins are not corroded or loose in the connectors.

If OK, check the engine Fuse Box as that will be responsible for providing the supply.

Fault Code:	C1380
Description of Fault:	Recirculation pump fault. Internal fault. The voltage supplying the pump motor is too low.
Conditions for Fault to clear:	The following conditions have to be met: - After switching the ignition off and then back on - When driving above 11 km/h
Downgrade Modes whilst Fault is active:	Cutting of all the ABS/ ESP regulating functions except for those for electronic brakeforce distribution REF. Switching on of the warning lamp and/or warning message: Warning lamp ESP Warning lamp ABS
Symptoms:	Lighting of the ABS and ESP warning lamps with error message
Suspect Areas:	Fouling External conditions ECU supply Fuse board (PSF1)

Thanks for the information that’s really helpful. I’d assume that should have been checked at the auto electricians when they looked at it.

Going to be a silly question. But are the DS3 like the C3. And you should have two powers to the pins at the pump. I think from research it’s pin 14 for the C3. As well as the main power and earth. As that’s what is confusing me. I’ve two big maxi fuses. One for abs and one for recycling pump. But only one power at the pump. Which is why I had the wiring checked by a specialist auto electrician. And are these like the C3 and have an abs relay ?

I'll need your VIN to check as the systems can differ. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

This was suggested by ecu testing there could be a blockage in the line. Which is another thing I need to check.

Ok, so we have a slight issue at present, as the server has been changed and as we are tweaking things, I can't provide you with a full Hi Res diagram at present, so here is just a low res extract of the main part.

Re C3 / DS3, no they are not the same as it depends on whether the vehicles have ESP as well as ABS. Then there is the variant of Teves system fitted that makes a difference.

The pins you mentioned above are for a standard ABS system by the looks of it and no the same as all. This is the extract of the Teves MK100E fitted to your DS3: According to this the 2 power pins are on pins 1 & 25 for the ESP system. On the ABS only they were on 1 & 14.

I'll get a full diagram up as soon as I can later on today, barring any issues.

Ok thank you very much for that information looks like the auto spark didn’t check it properly as I’d memory serve me right when I did my quick checks with the power probe. I only have one power to the bigger terminal.

I've been out and have just got back and been in contact with my colleague and we won't have diagram functionality back up until tomorrow.

That is fine I won’t be able to have a look at the car until Saturday. So I appreciate the help

While all this is going on, has anyone checked the battery output, alternator output & ground wires? Could be as simple as that as the pump does draw a bit of current!
