Suspension inactive is the symptom not the fault. Whatever caused the fault must be remedied before clearing the fault does any good.

"Looks good" doesn't help with a sensor. Read active live voltage of all sensors. If one is not functioning properly you should see one with voltage range that doesn't fit in with the rest. If one didn't read at all you'd get an error but if it just reads high or low, it just won't get to a value it's happy with to be able to calibrate.
