Crank, No Start: Code '4A63 EWS Manipulation'

Folks, this was an odd one. Probably my fault, but it seems to happen to enough people for various reasons that it's worth a thread someone can find in the future. Also, people get sold a new CAS when all they need is a simple software reset.

Symptom is that everything works, engine cranks fine -- but no start (and no SES light). Fire up INPA and you'll see various codes, but the one that's the problem is '4A63 EWS Manipulation'. Means that two modules aren't synched, so the car believes there is a security problem and immobilizes the car.

The fix is easy (with INPA). E60>>Engine>>N52 [in my case]>>Shft F6 EWS -- Start value comparison and Shft F7 EWS CAS -- Start value comparison. In my case, EWS CAS resynched the modules and the car started right up.

NOTE: My INPA had "valve" instead of "value". Since screwing with the valves in INPA is not something you leap into, it took awhile to figure the bad translation. Must have looked that this five times wondering what valves has to do with the EWS....

NOTE: Different engines have this selection in different submenus, I'm told. I didn't confirm this.

and NOTE: This can be caused by multiple issues with keys, but also by newbies getting too random while learning INPA. Probably what happened to me. I learned a lot while I diagnosed it, testing fuel pump ops and so on. Also, tried several Web suggestions (insert key in door twist left and right; or use valet key), and neither fixed anything.

So, if you get a "crank, no start", check for this fast fix via INPA. Good luck.

Good to know, thanks.
I wonder if this applies (value mismatch) to people who doesn't mess with coding via NCSexpert or INPA.

Don't know (of course), but in my search for the code I came across those who claimed it was out of the blue. Usually had something to do with getting new keys, thus requiring new key coding on a control unit in the car.

One more thing: there's no SES light. So, crank, no start, no SES light seems fairly unique. Even a bad fuel pump would likely trigger an SES light.
