BHI replacement

[MGmike]

No. Every good idea will be tried and reported back. The pump runs, all fuses good. Still F019 on the diagnos and suspension faulty max 90kmh.
Fluids on right level in tank.

If the pump runs, the two fuses required for the suspension must be good. If the car reaches the set height there must be enough LDS is in the system, therefore, I would suggest you look at the height sensors and dog bones to see if one is snapped or seized.

Thanks Marc.
Do you have a picture of the fuse box etc under the bonnet and or a wiring diagram for the car so I can start to see where the cut cables are supposed to go.
Thanks again to you and everyone else for the support.

The car doesn’t rise but I have full servo and the fluid reservoir are ”full”. I can hear the pump but has no communication to the computer. Quite interesting but frustrating.

[Kees]

It's a bit strange, you hear the pomp running, but the car will not rise, where is the pressure then going to?

[Cittotraang]

So, I have gone thru the fuses and finds no-one blown. What puzzles me is that I now have three different references of F39 but not one on the plastic.
When I have said that they are good, it is of the hard way by pulling everyone.
From the different pages here on the forum, I identify number 1 and number 4 from the top in the short standing bank "B".
The pic are of my fuses beneath the dashboard.

[Kees]

On the vertical blok, the 10A is the right one.

[Cittotraang]

Thanks. As MGmike said, there is two, which is the other one?

[Kees]

This is a mistake, the other one he means is the 40A fuse in the box near the accu.
But if this fuse is broken, the pomp doesn't working at all.
The suspension system use only these 2 fuses.

[Cittotraang]

Ok, so today after messing about with the fuses, I disconnected the pump and it stopped. BUT after I inserted the contact it hasn't started again.
I still have servo functioning, does it have its own pump anyway? The sportmode works but not up and down. I get suspension faulty but not with the max 90kmh warning.
The same error is, communication error in diagnostics.
Merry Christmas anyhow to everyone.

[Kees]

Ohh, i understand now, what you mean with servo.
You mean the pomp of the powersteering.
Because I have a 3.0 V6 this pomp is driven by the auxiliary belt, and not electrical.
This is why i ask, is the pomp (suspension) is running, where is the pressure then going to.
Now you have to find out, with somebody to help you is the suspension pomp does something, or nothing at all.
If it runs normal there is a distinctive sound, but when the pomp sucking no LDS, you hear a soft Buzzing sound.
If there is no sound check the 40 A fuse again.
Greetings,
Kees.

[Cittotraang]

Yes. My beautiful and the utterly intelligent wife and mechanical engineer have diagnosed the suspension pump as ”non functioning” and the 40amp fuse is good. Is a replacement of the suspension ECU the next step now?

[Kees]

Before this decision i should disconnect the connector with the 2 thick wires from the pomp motor and Measure if the 12 Volt is present.
If not, then look again at the 40 A fuse, but if the voltage is oke, then you have to replace the pomp.

[Cittotraang]

Ok, I'll do so. Can you take a picture of your fusebox so I can try to locate where my loose cables can be fitted?

[Kees]

Here you can see the red box, the location is in the left front side behind the left head light.
But remember i have a V6, so if it's not there in your car, send a question about the location in your car to Givemeabreak (Marc) with your vin number he can help you with this.
Greetings,
Kees.

I have that same little fusebox on my 2013 4-cylinder 163hp C5 as well.
