The various computer and electronic modules on your vehicle communicate over a "communication bus". This network or bus, is what allows them to send electronic messages back and forth so that they can "talk" to each other. When you get the "no bus" indication is means that this communication network has failed and the modules can no longer "talk" to other. At the same time this occurs all kinds of weird electrical issues are likely occur and this is all due to the bus going down.

2002 Dodge Durango. Got NO BUS, than it all comes back. No stalling etc., My air conditioning and rear wiper worked off and on, now not at all. 5 wire harness?


Usually the problem is the wiring harness or the body computer.
You may need a shop manual to get the wiring diagrams to troubleshoot it with.

Dodge Durango engine knocking and check engine light


P0300 is a Random Misfire
P0302 #2 Cylinder Misfire
U1120 The code U1120 means, lost wheel distance message. The powertrain control module(PCM) is not
receiving a signal from the anti-lock brake module. The problem could be a short in the bus circuit,
the PCM or the anti-lock brake module. This type of problem is best diagnosed by the dealer or a
local shop with the proper diagnostic scanning equipment. Hope this helps.

2002 Durango won't start change fuel pump, cramnkshaft sensor,


"No Bus" means something happened between the body computer and the engine computer. They are not connected to each other.
Usually a fuse, one of the computers, or the wiring harness in between.

Engine light comes on problem code is U1120


U1120 means the PCM doesn't receive a vehicle speed signal from the Anti-lock brake Module over the CAN C bus. This can be caused by the ABS module, PCM or something wrong with the can bus. This might be just an erroneous code and may never set again

What does it mean when it says no bus we changed out the fuel pump and the fuel relay.we let it run for 15 min but it just died out can you tell me what it might be


The ASD relay is your main power relay. Without it the car will not run/ Swap it with a look alike. Maybe your used fuel pump relay will be the same. We really need the code number to properly diagnose this.

Check engine light code p1698


A p1698 means the pcm is not recieving a bus message from the tcm. The vehicle bus is one wire that runs to each module as there means of communication. Could be a broken wire, bad connection, or possibly a bad module. Unless your pretty sure about what your doing and have some good wiring diagrams you should probably take it to your dealer.

1999 dodge durango 5.9 cranks but wont start no fire to coil,auto shut relay buzzes,has no BUS code on odometer,


It is your computer. I had this recently as well. No Bus means no connection to the on board computer. There is a company in Florida that repairs these computers, so don't get suckered in by the dealership for 750-1000.
