AIR SUSPENSION HAS NOTHING TO DO WITH ABS -

They have their own modules. If your compressor stopped working you need to get a rebuilt or new one - it should only run at startup for a bit, but if the air suspension has LEAKS, the pump is working overtime to keep them up at ride height, and it will FAIL and be burnt out - fix your problems first.

The codes in the EHC (air suspension) module are hard faults and need to be reset with DIS - so if you fix the leaking suspension you need the module faults cleared to be operational again.

Since you are saying all 4 of your wheels are low I assume you have EHC2 (2-axle air suspension) with the ride height button on your dash.

However, it is rare that all 4 air struts or bags are leaking, unless your compressor is dead completely I guess -

Get all 4 corners looked at to diagnose for leaks (I assume at least one or two are leaking, if not all 4) - Arnott Industries makes the replacements and sells a new compressor.

Worst case scenario your module might have been fried too - its a $700 part ending in 999 and needs to be coded to the vehicle.


The air suspension system works extremely well when it is fixed properly and quickly when something goes wrong. If you are having leaking air bags for weeks or months then you are also going to kill the compressor.
