2008 E350 Diesel Will Not Shut Down
My E350 Diesel van will not shut off. The key was turned back to the off position but nothing happen? I had to remove the Ravelco security key to shut the van off. After restarting the van it began to misfire and still would not shut off unless I pulled the Ravelco security key.
The van has been with the dealer for 4 weeks and they still can't find the root-cause. Here's is what has been done so far:
*Found a bad Diode (Week #1)
*Exchanged the PCM (Week#3-Did not fix the issue)
*Found corrosion in the Smart Junction Box (Week#4 replacement unit is on order)
As you can image, the dealer is stating the Ravelco system is the cause and Revelco is stating otherwise. With the recent finding of water corrosion in the SJB, the dealer is claiming water intrusion was due to Ravelco drilling through the firewall.
Has anyone experienced any water intrusion or corrosion to their Smart Junction Box? Will SJB failure keep the vehicle running even thought the ignition is on off position?
Your feedback is much appreciated!
