2001 Durango No Bus
information and found this, there seems to be alot of testing.... Hope this helps Vehicle: 1998 - 1999 Dodge Durango 3.9L 2000 - 2001 Dodge Durango 4.7L 1998 - 2000 Dodge Durango 5.2L 1998 - 2001 Dodge Durango 5.9L Symptom: Engine will not start. Gauges are inoperative. No BUS message displayed on odometer. System: Body/Chassis Electrical, Emissions/PCM/Fuel, Engine Electrical Codes: N/A Problem 1 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Crankshaft Position (CKP) Sensor. Test & Fix: If the 5v power supply circuit is shorted to ground, the CCD bus is unable to transmit messages and the Powertrain Control Module (PCM) appears to be "dead". The PCM is not damaged when the 5v power supply gets shorted to ground, but does need to be reset by turning the key off for 10 second after the short is removed. Using a DVOM or labscope, measure the voltage on the 5v reference wire at the Throttle Position Sensor (TPS) or Manifold Absolute Pressure (MAP) sensor. If 5v is not present, unplug the Crankshaft Position (CKP) Sensor. Turn the key off for 10 seconds. Turn the key on and measure the voltage on the 5v power supply circuit. If the voltage is now 5v, replace the CKP sensor. Problem 2 of 6: The 5v power supply from the Powertrain Control Module (PCM) is shorted due to a shorted Camshaft Position (CMP) Sensor. Test & Fix: If the 5v power supply circuit is shor

Won't start. As soon as ig.switch is turned on and try to start trans selector on instrument cluster switches down the line from P, R, D, 2, 1 over and over and then shows no bus error code. Tried to reset computer by disconnecting bat. Checked connectors on computer, unplugged and replugged in. Don't have a clue what to do. New member.

It is toast. IndyDurango __________________ - Truck of the Month:

Scott Crouch New Member Likes: 0 Does anyone happen to know what Error Code No Nu5 means in a 2000 Durango? Scott Crouch, Jun 12, 2016 Share Mopar-Related Post #1 t vago Member Likes: 8 I think it is actually trying to show "no bus", but one of your number segments is no longer working. What engine do you have in your Durango ? Does this occur all the time, or only after some period of time? t vago, Jun 12, 2016 Share Mopar-Related Post #2 Scott Crouch New Member Likes: 0 Hey, thanks for the response, t vago! That's it, "no bus". It's a 5.7. It started a couple of days ago and it's doing it after approximately three to five minutes of running/driving time.

I also can hear something turning on, like the sound of an electric fuel pump turning on, coming from around the engine compartment near the front left wheel. I've disconnected the negative battery terminal in an attempt to reset the computer but that didn't help. I was going to try anot
