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. **** correction to title. Won't crank. ***** |
Did you only wash the exterior with the hood closed?

it was washed and sat for an hour before I started driving.. the engine bay was dry. i did have some leaves in the hood / wiper area.. but no visable water in the interior |
CPS was repalced and now car cranks, BUT still not 100%

Won't crank. ***** 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? |

Remove the Instrument Cluster and its connector. Then try to replicate the problem and see if the problem still exists.

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. -Nick |
With the hood closed water cannot effect the Crank Sensor.

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. |
