Suspension warning light

Having had various suspension issues last year I replaced the compressor with standard Hitachi and fitted a new air reservoir because the old one was leaking. So with great satisfaction all warnings disappeared and I had trouble free motoring and suspension for 6 months.

Then all of a sudden amber suspension warning came up a few weeks ago. Suspension seems to be OK, although it takes ages to lift to off road height and comes up with a message saying "suspension raising slowly" or something similar. So I took the plunge and bought a new IID BT from Ebay at a very reasonable £375. Smile

So I read the fault and it says this:

IIDTool BT V3.0 B2444 Suspension • C1A26-16 (AF) Temperature sensor circuit - General electrical failure - circuit voltage below threshold


Pump does work but the system temperature live value says 199°c which is obviously not right. So hoping it's a faulty sensor or wiring fault.

Has anyone else come across this?

Forbes.

I meant to say the compressor temperature is 199°c but the motor temperature is up to 52°c when running.

Hi, yes. It was a faulty temperature sensor. I managed to get a second hand replacement and it's working great now.

Mine is a Hitachi comp, but if you have the same fault code it's likely to be the sensor or a broken wire. Check wires first as the replacement sensor it got I thought was also faulty but it had a broken wire which I cut out and replaced.
