  2. Does anyone know what pin 6, 7 and 14 (SCI) on the data link connector are used for? I know pins 3 and 11 are CCD. I am trying to figure out why I am getting live data on my ODBii scanner such as speed, engine coolant temp, RPM etc and yet my cluster shows nothing. I was wondering if SCI is a link to the ECM or PCM that bypasses the CCD bus for the ODBii scanner. Furthermore is the data is coming to my scan tool on the SCI pins of the DLC, does that mean my PCM is ok? Any guidance? Thanks, Bill
  3. Hi everyone. I have a 2001 24 valve Dodge Ram 3500. Issue: Stopped for around 30 minutes and when went to start my truck, no instruments work and I get bus failure / no CCD. Truck runs fine with no issues on shifting. I do get wait to start light and several indicators light up on the cluster but stay lighted (like check engine, abs etc). ODBII Codes: P1698, P1694 and then P1698 again. Cluster Codes: 900, 920, 921, 940 and 950. Also 999 but I think that is just end of test. When I go to tranny DTC iwith ODBii scanner, I get P1687 and P1694 Other comments: Can't get to eng
