My wife is driving my pickup while I am deployed and the SES light came on, she took it to Auto Zone and they said it was fault code P0380. I have a list of codes but only for 2004 and the fault was not in there. Does anybody know where I can find the fault code list for 2002 along with an electrical schematic? I know her dad can do the work if I can give him a place to look, he is a competent mechanic just not a diesel mech. I would appreciate any help.

If you mean a P0380 I've seen them when the key was left in the start position for a extended period of time,truck not running.

P0380 is a Glowplug DTC.If the truck is running well and doesn't repeat I wouldn't worry

The problem has repeated. I just need to know where I can find a list of the codes and what causes them for the 2002 and an electrical schematic.
