Hi,

I'm having a hard time diagnosing my suspension issues. Both my front air shocks are down to their bump stops. The compressor runs for about a minute and stops. I get the amber light and the EAS is disabled from raising the car. I've serviced the dryer with new desiccant, filter and o-rings. I’ve cleaned the front valve block and checked for leaks but didn’t notice any. I used a generic OBD2 reader and read the following codes:

c113192
c1a0196
c1a0294
u042194

Anyone know what might be the cause of the problem. Thanks.

 

If the compressor is running for only a minute, then I suspect the compressor itself is on the way out or the system has a major restriction. If the amperage draw is too significant, the system faults. Or if it exceeds the maximum run time - but I know that is over a minute. If its running too much and overheating, the display will say as much. But you did not mention if the front end is even tasing a little. If its not, then it will also fault and you probably have an airline leak OR when you serviced your airblock, the lines were hooked up wrong (it has happened before).

 

Thanks for the quick response. The compressor didn't feel hot but that could be different than the internal temp. How can I measure the current draw? Would there be a code for the high temp or current draw?

I'll double check the air hose going to the front valve block. Hopefully it's something as silly as that.

 

I double checked the front valve block connections and they look fine. I've also performed a hard reset, but that didn't do anything.

 

 

Any recommendations?

 

Is it raising at all?

 

No. It'll just run for 30sec and stop. Then the amber light comes on.

 

And you had these issues before you serviced it?

 

I serviced the dryer and front valve block because of the front suspension and amber light issue. I thought there was a block somewhere.
