Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I will assist you today."No Bus" means that the instrument cluster is not receiving any data from the other computers on the truck like the PCM (engine computer), air bag module, body computer, etc.Did you have this issue before the truck sat for 9 years?
Ok, the next step is to measure the CCD bus voltage at the data link connector You should have 2.5 volts at terminal 3 and also at terminal 11. Check that and get back to me.
Click on the link below to see the connector.
Hi Larry, No I want you to check The CCD bus voltage (Chrysler Collision Detection) at the data link connector under the left side of the dash. I will send the link again. You should have 2.5 volts at terminal 3 and also at terminal 11. Set your DVOM to DC and probe the terminal with the red lead and the black lead to a good ground.
I will send the link again.
Hello, just checking back to see if you received my last reply. Please let me know if you did or did not. I can always send it again.
Aha ! After you said that, I think that you may have a problem with the Central Timer Module (CTM ) or the over head console module. there are 2 possible locations for the CTM . It is behind the left kick panel next to the parking brake , or to the right of the glove box. pull that left kick panel , and if you see a thin module (plastic box with connectors plugged into it), then that is the CTM . Disconnect the connectors going to it and see if the problem goes away. let me know .
Ok , sounds like it is the CTM. it is just to the right of the glove box on that year Dakota. Disconnect it there, and then see if the no bus message goes away. Keep me posted .
The CTM does contain the circuitry for the door locks, dome lights, and wiper delay, but has nothing to do with the stereo or blower motor. However it sounds like you are getting close! And to answer your question about the amplifier, yes it is under the passenger kick panel. I think you are about to solve this!
You do not have to pull the dash. I will send you the procedure. Be right back.

Let me know if this helps.
