Tu as beaucoup de chance, c'est juste une alerte de niveau de liquide bas dans la centrale. Si la vidange n'a pas été faite il y a moins de deux ans, fais faire une vidange complète et purge des 4 circuits, c'est le bon moment!JCP a écrit:Ils clignotent comme dans le dernier exemple.

It works!!! - ABS 2 fault reset (long)
I have just carried out a reset of my ABS 2 :dance:
This is for 99/2000 model LTs.
It is not for models with integral ABS.
It has been suggested that the only way to clear ABS2 faults is by placing it on the diagnostic computer at a dealers shop.
I have just proved that this is not true. It can be done at home relatively simply.
What I am describing clears the memory of faults and returns the abs warning lights to normal on startup. If however you have failed to cure the cause of the fault, eg bad wheel sensor, the warning lights will return to their warning state once the bike has gone through it's self test process.
Firstly you can do some investigation of your own fault codes.
Under the front seat and clipped to the frame there is a diagnostic connector. It is cylindrical in shape and has a removable push-and-turn grey cap.
Remove the cap and locate the pin 2 - connected to a brown/blue wire. Connect an analogue meter between pin 2 and earth. Turn on the ignition. The meter will initially settle at around 10V. It's what happens next that is of interest. The needle will fall to a number of lower voltages in a series of pulses. Count the number of needle drops. This number is your fault code.
The following codes have appeared on other forums. I cannot guarantee their accuracy but they may point you in the right direction:-
1.Front pressure modulator.
2. Rear pressure modulator
3. Front wheel speed sensor
4. rear wheel speed sensor
5 battery voltage too low
6.ABS relay
7.ABS control unit
8. sensor gap front or rear or other outside influence.
9. Unknown .....
16. Failed plunger test
Ok. This may help you cure the actual fault which is causing the alternating (wigwag)warning lights.
To carry out a reset, this is what I did. You need to get to pin 21 on the ABS controller. The connector is plugged into the abs unit which can be seen next to the battery holder towards the left hand side under the seat.
I removed the battery to create some space.
Now this is where it became challenging. I didn't want to remove the whole unit just to release the connector.
As you look down from above you can see a protruding rectangular steel clip at the bottom of the connector. You need to push this down whilst you prise out the connector from the bottom. No easy feat but I managed. Unfortunately, the connector continues to be held in at the top of the unit. The connector itself has a plastic lip which hooks under the top of the abs unit. You will see a small screw in the top of the connector. Do not remove this - it will not help - it has nothing to do with release.
Lack of space meant that I could not revolve the connector sufficiently to release the lip. After much knuckle bleeding I used half a junior hacksaw blade to saw the piece of plastic from the connector. This allowed it to come free. On final replacement I will tie wrap the connector back in place for security.
I then had to dismantle the connector to reveal the wire locations. I had to roll back the rubber protector tube where the wires enter the connector. This reveals two screws. There is another screw at the top of the connector. Remove all three screws and then pull the connector block from its housing so you can see where the wires enter the terminal holes.
The inner connector has its terminals numbered along the sides. Terminal 21 is vacant. I stripped a thin wire and threaded it through the hole and then bent a small amount over to hold it in place being carefull not to interfere with other terminals.
I then carefully replaced the connector onto the ABS unit and replaced the battery.
OK. The reset. I earthed pin 2 of the diagnostic connector and kept it earthed.
I then switched on the ignition. Both ABS lights were flashing alternately. I then grounded the wire from pin 21 and made a count of 8 seconds. As soon as I grounded this wire one abs light stayed on and one went off (can't remember which one). At the count of eight I removed the pin 21 wire from earth. This results in both abs lights staying on together.
I switched off the ignition and removed the diagnostic earth wire.
When I switched the ignition back on, both abs lghts were flashing simultaneously. Just as they should.
I'm going to leave the pin 21 wire in place so that I can reset in the future at will.
Hope this proves helpfull to you all.
