C5 Suspension pump motor not stop

Post by Tsunami »

Hi all, i have Citroen C5 Mk1 and i have a problem with my suspension pump. It never stops running until i disconnect the small connector on the pump motor. Can anybody help me?

By the way if it is possible, i want to solve the problem without change or modify the suspension ECU. If not i can try to modify it but i couldn't find the which coil is for raise. Can anybody mark the soldering points?

Have you checked the lds fluid level, if low there might not be enough to raise the height to its normal level. May also be a level sensor fault, it is worth greasing the sensor pivot joints every now and again so they move smoothly. If it does this when the front wheels are turned to the left or right it could also point to a sensor problem.

LDS fluid level is ok, height sensor is ok, car can leveled itself correctly. And I can raise the car top position and lower to bottom without any problem except motor running continuous already lowering or balanced.
