Xantia HA2 problem
I believe my Xantia is stuck in hard mode.[xx(][:(]
I have swopped out the rear HA valve/solenoid and HA ecu (abit s/h).
Does anyone know the voltage that the ecu sends to the HA solenoid to operate the HA valve for soft mode?

I think that if one of the solenoids (front or rear) is disconnected, the computor senses that not enough current is being drawn and goes into that mode where it just gives a short burst every 30 seconds or so (presumably to detect if the fault has cleared). Do you hear both the solenoids operate for that brief pulse?
Bernie can you do an ohm's check on the solonoid coil ? (cable removed of course)
I dont have a clue on the power consumption on these valve coils.
If they consume something like a standard relay coil - then there should be some 60-120 ohm in the coil. This is an equivalent of some 0.2-0.1 Amps and then you can use a medium wattage - say 5watt (side/rear light) bulb - as a series resistor.

Thanks Mike, yes they are both humming.

I've asked about the ohms test before Anders and unfortunatly there is a diode across the coil.
The resistance across the coil is 4.2 ohms.
I just want a way of permanantly setting it in soft mode for the time being until I can sort out why it's so hard

That's one coil.
Same result both ways which would indicate the diode had gone open circuit but apparently not according to the guru's

Bernie, according to the Citroen workshop manual, the supply voltage should be 2.6 volts with a resistance of 4 ohms.

Is that a continuous dc voltage to keep the ha in soft mode?
