#1982 of 3275 No Bus - Dead Dashboard
Jul 15, 2005 (9:37 pm)
I'm having the "No Bus" message show on my 1999 Dodge 1500 Ram pickup. it's a manual with a 318. This happens when I'm idling or on the road. It doesn't seem to matter if A/C is on or any other electrical device. It seems I just have to wait a period of time and it starts up again. The No Bus message in the odometer window dissapears then goes back to the mileage reading- that's when I can start it back up again. I saw another thread on a Dakota. Does anyone have any idea as to why this happens? the code reader brings up nothing!

On older RAMs the "NO BUS" message means that the Programmable Communications Interface (PCI) data bus circuit is inoperative. This circuit is the data exchange between the PCM and other various computer modules and circuits in the vehicle.
The following could be reasons for a "No Bus" message:
*A instrument cluster CPU, RAM, or EEPROM failure (includes bad grounds or broken circuits on the instrument cluster PC board)
*A poor or broken PCI data bus connection at the instrument cluster
*Certain instrument cluster fuses may be open

Thank you. Hopefully my Mech will have the right equipment to pinpoint and figure this one out! It turned off 3 times on me today already- 2 times at a busy intersection after 3 days of no problems.

I also have had this problem with my 1999 Ram pick-up Quad cab. We were on our way home from a camping trip (towing a 14 ft popup camper) and the A/C began blowing only from the window blowers (blowers were set to mid-body). The brake light and ABS light came on at the same time. The Cruise control stopped working all together and when we came to a stop, the speedometer didn't work until we got up to 20mph. Now the Check Engine light is on and the speedometer doesn't work at all. We have checked allof the fuses but saw that there is a sticker attached to the inside of the hood that shows a diagram with all of these things directed to somewhere. (couldn't figure it out! ) Please help!!!!! Thanks!

I am having the same issue on our 1998 Dodge Quad Cab, first the ABS light and Brake light came on then the spedo quit and check engine light came on. I ran codes and had a speed sensor fault, rpl speed sensor no luck. Problem seems to come and go, when spedo stops working is when check engine light comes on. A few times driving spedo starts working, I turned engine off restarted all was OK not warning lights, went a few more miles and ABS and Brake light came back on.
Any help is appreciated.
#1988 of 3275 Vacuum Hose

What is the best way to check vacuum hoses on my '98 1500 360ci? There is a hissing noise when running, and I have to crank twice before start. Thanks!

I've found that a good visual inspection with the engine off uncovers 80% of them. Look carefully at each line for splits and cracks. Move the vacuum lines around to expose split areas. If any lines are showing signs of embrittlement, these should be major suspects. Have you or anyone else performed any service on the engine recently? Look in those general areas that were disturbed. Many times the act of repairs cracked a brittle hose.
If that fails, obtain a stethescope and run it along all of the vacuum line with the engine running.
Good luck and best regards,
