(b) Malfunction Code Indication
0 In the event of a malfunction, the light will blink
every 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 code.
0 After all the codes have been output, there will be
a 4.5 second pause and they will all be repeated
as long the terminals TE1 and E1 of the check
connector are connected.
HINT: In the event of a number of codes, indication
will begin from the smaller value and continue to the
larger.
2 Trip Detection Logic
Diagnostic codes 21 and 25 use "2 trip detection
logic". With this logic, when a malfunction is first
detected, the malfunction is temporarily stored in the
ECU memory. If the same case is detected again
during the second drive test, this second detection
causes the check engine warning light to light up.
The 2 trip repeats the same mode a 2nd time. (Howev-
er, the ignition switch must be turned OFF between
the 1st time and 2nd time.) In the Test Mode, the
check engine warning light lights up the 1st time a
malfunction is detected.
After the diagnosis check, remove the SST from the
check connector.
