Air suspension pump testing.

<< < (6/9) > >>

Range Rover Blues:
Now you are asking.  I think ther may well be one for the pump under there.  I have a snealking suspicion there may have to be a relay as well, though I never hear mine click on and off. Otherwise the ECU is handling about 12 amps, that's what the pump draws off my battery charger.

DAVE39V8:
Just took a gander at the handbook and the 30amp fuse is for the air suspension compressor(maxi fuse)..Will check this 2mrw.

Is there anymore fuses I should search for incase that one ok:?:
Like I said before I appreciate all this help.

Range Rover Blues:
Now I really need to go look at a manual :wink:

I'll get back to you soon.

DAVE39V8:
Ok RRB thanks again

Range Rover Blues:
Right, if you found a 30 amp fuse under the seat then keeping it company are a large relay that gives the EAS a 30 second delay to self-level after turning off the ignition, a 5 pin relay that runs the warning light on the dash and a 4 pin relay that runs the pump itself :)

THis relay needs checking, even if it's just to see what's going on.

The pressure switch is if I understand correctly open circuit untill the pressure reaches 10 bar nominal, it stays that way 'till the pressure drops to 8 bar.
So if you disconnect it the pump should run.  Sounds wrong to me as there is no failsafe in that logic, but that's the way I read things from the manual.

The temp switch is better, it goes open circuit when the pump clears 120 degrees (ouch) and it goes to earth, so you need to check the continuety of the red wire on the motor to earth, if the contact is broken the pump won't run, so try shorting the red wire to earth.

If you are still struggling then I have found the pinout of the ECU for you, you will have to check through it in order to check what's going on.  You can also use it to manually inflate the EAS if you can get the pump to run.
