This one Kicked my *** the first time I got one
The crankshaft sensor shorts out internally and grounds the 5V wire the modiules use to "talk" to each other.
That's all, If you have a scan tool you think lightning hit your car 'cause you can't get any info from any module
climb under the passenger side of your truck with a new crank sensor and a 10mm ..... anything, one easy bolt holds it in!

John - thanks - you just saved me a bundle on trying to find a new PCM or paying $700+ for an instrument cluster (the local mechanic I use had the exact issue you said - no commo using the scanner & called a buddy at Dodge who said it was a circuit board on the instrument cluster that was overheating). Anyhow, I'll get one tomorrow and pray it takes care of the problem so me and my open fisherman can get some lobster next week! Greatly appreciate it - let me know how I can pay you back (I have some excellent cigars from the Canary Islands - could send you a couple!)
'99 Silver Durango 5.9L 2x4 w/ Tow package
ok im no mechanic well actully i rebuild alison transmissions or at least i use to but i have a 99 dodge durango and had the same problem no bus on the odometer i freind contacted a friend at the dealership and they told them it was one of three things its the computer, dash cluster or loss wireing but one thing that will tell you if its the computer is if you hook a scan computer up on the inside of your car and the vehicle powers the scan devise up but reads nothing then it is most deffenitly the computer gone bad which will run you about $375 rebuilt with auto zone which takes 4 to 6 weeks or you can get a used one no warrenty for the same price in about 7 to 10 days but i have another problem now i think my ignition is bad from the same time because it wouldnt start but i ran a targa switch from battery to starter selinoid and it started right up if its not one thing it is another
We have a 99 dodge durango that is stalling and we have replaced the crank sensor but, after picking it up today it stalled again! we are so frustrated as we've only had this vehicle for maybe 4 weeks and 2 of that its been at the mechanic trying to get it to stall so, they can read a computer code. HELP!!!!! we are at our wits end!
I have a 99 D that kept stalling and never under the same circumstances, hot, cold, just started or running for hours.....We tried the crankshaft thing and a control module thing they said would fix it, it didn't.... My problem was the PCM, and it was under warranty up to 80,000 miles, so they gave me the run around because they really didn't want to give me a new one for free....Go for the PCM, Good Luck.
I went ahead and bought a new/remnufactured one from ecu direct.com for $434 and it fixed it. But the trucks being repoed soon. So Ill be pulling the good one out and reinstalling the bad one. So anyone that wants to get rid of their "no bus" problem for good make me an offer and Ill let it go. My email is Custnam@aol.com Thanks
I'm trying to replace the crankshaft position sensor module. How do you remove the plastic grommets on the inner fender splash shields? I tried popping them off, but found that they were threaded in. The grommets are circular with a circular indentation in the middle. Not sure what kind of tool to use to take these off. Help please....
The "no bus" code strikes again. Truck was plowing for 22 hrs straight and died out of no where. I have a 2002 Dodge Ram V/8 manum ext. cab p/u with an 8" bed pushing a 7 1/2' western minute mount plow. Bought used in 2005, never a problem till recently. First the tranny lost reverse & had to rebuild with a h/d shift kit. Next came the headlights, lost the low beam, Brights worked but the low beam didn't. Had to replace the ground wire @ the module. Most recent is the infamous "no bus", after turning off the truck while refueling we started the truck and after putting it in drive and gave it gas it stalled.
We'll, My Durango (2000 5.9L) is getting the "no bus" as well. I am trying to determin if it is the ecm that went bad. The problem that I have read on other forums is that the board inside the computer may have cracked or wraped and if you move press in the the plugs your car will run again.
1. Key in the on position
2. Use your hand and press and move the wires around on each of the connectors that goes into the ecm. Listen for the relay to click (Relay box located right behind the battery). Now go back and start your truck. Mine happens to be the connector closest to the firewall. I have read others that the middle plug was the issue.
Here is another writeup on Shut-down Feature in Dodges http://www.ehow.com/how-does_4924742...l-driving.html Shut-down Feature in Dodges
Dodge vehicles have a similar shut down feature. The shut down feature in Dodge vehicles is located in the computer. It is called the auto shut down relay. It will shut the vehicle down if the vehicle rolls over. There is no way to manually turn it back on. If this switch goes bad, the only way to fix it is to replace the computer.
All vehicles have an idle air motor or valve. The idle air is governed by the computer and changes the idle. When you turn on the air compressor, you use some engine resources. This makes the idle speed on the engine drop. The computer senses this drop and sends information to the idle air to turn up the idle so the car does not stall. If this part breaks, when you slow down to a stop or to turn a corner, the car may stall.
Just today, my car wouldn't start by doing the above mentioned. When the transmission was in park. But, when i put it in neutral it starts. This was off & on incident. Decided to replace the neutral safety switch located on my tranny (part 56028181). This part is tied into the ignition system. I'm hoping that this fixes the problem. I will report back if this does not fix the problem. My thoughts are could somehow the swithch was bad, so, while your driving it tells the ecm that tranny just went to park and to shut down the motor? Any thoughts from more experienced techs would be great.
I will be replacing the ecm if the neutral safety switch doesn't fix it.

Are you using water wetter? I've heard good things about it's ability to improve cooling efficiency. I wouldn't use it if you have even the smallest coolant leak though. It reduces the coolants surface tension and will leak a lot easier.
