Help-
I have a 1998 ML320 that will not run. It will sometimes starts and dies immediately , and sometimes the starter will cut out early.
My light on the dash above the fog lights does not come on and off as mentioned in other posts.
The code I get is p1570 DAS to ECM interrupted CN3/10 Drive authorization system
Does anyone have a diagnostic proceedure for this or any other info.
thanks in advance

Did you try using a different key to start the truck. The FOB might be malfunctioning...

I only have 1 key and wanted to diagnose the problem before I ordered a key .
thanks

The key is the MOST likely problem!

You're asking for trouble by only owning one key!!! If the DAS portion of the key fails, you're stuck!!! The first step in diagnosing DAS is using a known good key. In my experience keys are at fault about half the time. This week alone we've had three '98 ML's with DAS problems. One faulty key, one bad AAM and one bad immobilizer. Order a new key before you do anything else. Even if it's not the problem you should have at least two anyway.
