Please can anyone help? I need to fix the suspension so an engineer can take the car to replace the gearbox.
Replaced front height sensors
Replaced valve link under the front wheel arch.
Removed and checked the suspension valve block next to the reservoir - which appears to work fine.
Checked the steering sensor.
Checked for corrosion on ABS plug connections.
Not checked the rear height sensors yet.
There is a CAN bus fault.
I bought an iCarsoft LR V2 which gave this reading before I replaced or checked the above things:
It also gave this reading - which is the part number for the Air Suspension Control Unit - I am wondering if that is worth replacing or if it would be a good idea to check wiring first or corrosion on the plugs of the control unit:
I don't have a diagram which shows the route for the wires which does not help. I have the colours.
Can anyone help explain where the wires go?
Are there any other things on the CAN line which may cause the suspension to stop?
The history of the suspension fault - follows:
a) Tampering about with a radio which fell off it's speaker wire and I was worried in case I dislodged something.
b) Replacing a front anti-roll bar which required partial removal of the sub frame.
Before complete suspension failure, the left front suspension tended to throw that front side of the car in the air when going round left hand turns (I would assume pressure would be needed on the right hand side when turning left) - which is why I started the process of repair by replacing the height sensors at the front.
On the last journey (350 miles) the front of the car sank to the floor (-100%) and the rear rose to maximum (+100%).
Is it common for the EAS ECU to fail?
How can I reset the suspension when I plug everything back in?
I have tried a reset with 3 different diagnostic tools.
I tried to reset by turning the wheel.
Is there any open source PC/Linux/Mac based software to communicate with the car computer?
If anyone would help me with a route for the wires that would make it easier to test the CAN lines.
The gearbox is not working - so that is another fault - but I am assuming transmission it is on a different line to the suspension and will not cause an error in the suspension CAN lines.
THANKS
