if the computer sees more than one

occurrence:

different times.
(Codes have unrelated causes.)

--Notice how the codes are grouped and
the code group is repeated.
NOTE: Some early fuel injected models
(typically 1986 & 1987) may use short
flashes for displaying
all codes. The
flashes are 1 second long with a 2
second pause between codes. Both
single and 2 digit codes are sent as one
long series of flashes. For example, a
trouble code 13 would be displayed as
13 consecutive short flashes (instead of
1 long and 3 short flashes).
5) Write down all displayed Trouble
Codes.
6) To view codes a second time, turn
the ignition key OFF and then back
to the ON position.
7) This completes trouble code
retrieval on these vehicles. Turn the
ignition key
OFF. (The
engine
computer is
back to
normal
operation.)
