If you own a Chrysler vehicle and encounter a no crank, no start, no crank no start no click, read this post.
If you own a 2007-09 Chrysler vehicle and encounter a no crank no start condition, chances are you have a locked up Wireless Control Module (WCN). The wireless control module also handles keyless entry. Chrysler Technical Service Bulletin #08-007-08A entitled: No Engine Crank or No Engine Start Due to Electronic Lockup of the WCM or SKREEM, addresses the problem. SKREEM stands for Sentry Key Remote Entry Module. The bulletin applies to vehicles built on or before May 05, 2008 (MDH
You may also find that the remote keyless entry doesn’t work. Or the engine may crank but not start. The WCM is a computer and it’s susceptible to static electricity lock up. The condition may happen more often in dry or cold weather.
Remove the key from the ignition and then remove the IOD fuse. Wait 10-secs then reinsert the IOD fuse. If the vehicle starts, you’ve found the source of the problem. However, don’t think you’re done. This module will act up again.
Chrysler has redesigned the module and insulated it better against static lockup. The new module must be programmed in the vehicle to make it work. If your vehicle is equipped with an electric steering column lock, you must replace that as well. The affected vehicles are listed below:
2007 – 2008 (DR/DH/D1/DC/DM) Ram Truck (1500/2500/3500/4500/5500)
