I have installed new air suspension compressor, new front right wheel speed sensor and a new brake switch. U0416 sometimes gets cleared and registers as a fault while C1A96 doesn't clear at all.
Non of the height sensors reported as faulty during diagnosis.
I have unplugged them and have not seen signs of water intrusion.
How do I check it?
Where is it located?
Under the driver's seat?
I didn't see anything like ECU under seat.
Ok on some models it can be under the passenger seat . Did you look there?
Not there too.
Just located it. Do I need to program a new one?
I have just installed another air suspension ECU from another LR3 but the suspension fault signal on the dash is red with special programs off. No improvement.
Sure, the battery was disconnected.
U0416 and the brake switch errors are still persistent.
The brake switch was also from the other LR3. The new dealer ECU is an updated version. The suspension fault indicator was also red when installed. It only says wait without giving access to perform tests or clear errors.
Just got a new switch and nothing changed.
Ok there has to be a broken wire in the communication line then was this checked?
How do I check?
Just took my time to trace the harness and have found nothing.
UO416 and C1A96 refused to go out.
Where is the sill?
Are there specific wires to check?
Have spent much of my time checking the wires and all are good.
