PGM-FI SYSTEM
ERASING DTC
• The stored
OTC
can
not
be
erased by simply disconnecting the battery.
Connect the MCS tester to the DLC (page
4-11
).
Clear the
OTC
with the MCS while the engine
is
stopped.
To clear the
OTC
without MCS, refer to the following procedure.
How to clear the DTC with SCS connector
1.
Connect the SCS connector
to
the DLC (page
4-11
).
2.
Turn the ignition switch
ON
and engine stop switch
"O".
3.
Disconnect the
SCS
connector
[1]
from the DLC
[2].
Connect the SCS connector
to
the DLC again while the MIL stays
ON
about 5 seconds (reset receiving pattern).
4.
The stored
OTC
is
erased if the MIL goes off
and
starts blinking
(successful pattern).
• The DLC must
be
jumped while the MIL lights. If not, the MIL will not
start blinking.
In
that case, turn the ignition switch OFF and try again
from step
3.
Note that the self-diagnostic memory cannot
be
erased if the ignition
switch is turned "OFF" before the MIL starts blinking.
CIRCUIT INSPECTION
INSPECTION AT ECM CONNECTOR
• Always clean around
and
keep any foreign material away from the
connector before disconnecting
it.
• A faulty PGM-FI system
is
often related
to
poorly connected or corroded
connections. Check those connections before proceeding.
• When testing at connector (wire harness side) terminal, always use the
test probe. Insert the test probe into the connector terminal, then connect
the digital multimeter probe
to
the test probe.
