Please help. I was driving home from a nearby town, and my CEL came on, all of my dash gauges quit working and the odometer says "NO BUS". When i got home, I scanned for codes and came up with these:

-P1698 - No CCD, message fom TCM

-P0383 - Generic Grid heater relay

-P1687 - No mechanical instrument cluster BUS message

-P1694 - No CCd message from PCM - Aisin transmission

-P0122 - Low imput throttle position sensor circuit low imput - I replaced the apps 2 months ago with a Timbo unit.

Any insight would be much appreciated!

--- Update to the previous post...

Any chance i have a bad ECM?

I am glad it is fixed. Thanks for this thread.

Well I was right about the diagnosis but as for location that a bit tough... But like I was trained for Computer tech support you want to look back over any modification that the owner last did. It might provide a clue. Even I tend forget about my own advise at times... :banghead:

I agree. Usually I assume that something I did may not have gone quite right. In this instance, it had been so long, I had forgotten that I'd even replaced the switches. On the bright side, these types of problems always pay off as a learning experience. --- I am here: http://tapatalk.com/map.php?bvc4fo Sent from my iPhone using Tapatalk
