4. Read the diagnostic code as indicated by the number of
flashes of the "CHECK ENGINE" warning light.
Diagnostic code (See page FI-26)
(a) Normal System Operation (no malfunction)
• The light will alternately blink on and off for 0.26
second intervals.
(b) Malfunction Code Indication
• In the event of a malfunction, the light will blink ev-
ery 0.52 seconds. The first number of blinks will
equal the first digit of a 2-digit diagnostic code and,
after a 1.5 second pause, the 2nd number of blinks
will equal the 2nd. If there are two or more codes,
there will be a 2.5 second pause between each.
• After all the codes have been signalled there will
be a 4.5 second pause and they will all be repeat-
ed as long as the terminals TE1 and E1 of the check
connector are connected.
HINT: In the event of a number of trouble codes, indica-
tion will begin from the smaller value and continue to the
larger.
5. After the diagnosis check, remove SST.
