Help. All warning lights stay on after key removed & wont start
So I washed my 2003 ml350 with a Garden hose. Etc. drove 10 miles parked, restarted. Drove 5 min. Parked. Drove 2 min. Parked. Restarted fine. After 2 min. Noticed the car turned off. When I tried to restart. All the warning lights on the dash came on and car wouldn't even crank. I took the key out and the warning lights stay on. It won't turn off until I disconnect the battery. Then the doors unlock via remote and lock alarm works to. Once I put the key in pos 2. The lights all come on hazards blink and vent starts blowing. I can't connect the Obd scanner ( generic ). It says vehicle not responding. The key won't lock or unlock the car until I disconnect the battery
I have Replaced relay 12 but same issue occurs.
Any help would be appreciated.

It cranked and started.. the strange thing is when I turn the key to position 2 the speedometer needle vibrates until the car turns on . also all the other gauges stay off for a good 30 sec after start and then become active.
any thoughts?

i replaced it and it started right up... the only weird thing is that it takes a good 30 secs, for the gauges to activate ( Fuel and RPM ) and the speedometer shakes at startup.. and a weird ticking noise.

SO its been running fine for the last few days.. and today it turned off again while driving.. and i couldn't get it started. I did not wash it this time... so its definitely not the CPS. which i replaced.
I am going to try to remove the cluster and see if that does anything

Removing the I.C. will do noting at this point. The problem does not occur often enough.
It's time to have the codes read with a professional grade scanner, not a code reader.
