gift so he can do diagnostics (ie. check engine light) ?

pepboys..)

Buy a Hanyes manula or even the Chilton's version and learn to pull
codes WITHOUT a scanner, which quite frankly, is quite easy.

for the benefit of all readers, why not post your understanding of the steps
or perhaps a link that explains it?

especially if it is "quite easy"

many thanks in advance!

I found this via google groups, hope it helps (the author was ayeldram with a yahoo
address, no sig in original post)

There is 3 pin plastic connector sticking our of the middle console
next to drivers right foot, jumper pin 1 and 3 with a paper clip when
the Key is "ON" position but truck is NOT running.
The "check Engige" light will start flashing, it will flash each code
for 3 times. It is a 2 digit code it will flash the first digit then
pause and flash the 2nd digit, then lognger pause. e.g
flash-flash-flash-flash Pause flash-flash-flash-flash would be "44".
Once get the code either look at the Haynes manual or search the web
for what it means.

Ignore first code, which is 12 and it will flash for 3 times. All it
means it that computer is getting into the diag mode and also give you
enough time to get ready to observe the real code.

By the way "44" is the one which means Lean condition which could be
contributed to the O2 sensor or EGR Valve.
