When i go to run a Self Diagnostic on my 2002 Dodge Caravan SE the odometer window displays Sof 4.1 with a fault code of 400.1.

I have an excellent PDF service manual "2002 RS/RG TOWN & COUNTRY, CARAVAN, AND VOYAGER" but some fault codes aren't mentioned such as the 400.1. What is that? Is there a newer version of this PDF manual available for my vehicle?

Thanks

 

Could you please advise where you were able to find a PDF copy of the Service Manual. I've been trying to find one for my '02 Caravan SE.
