BEFORE MIL TROUBLESHOOTING
• When the MIL blinks 1, 8 and 9 times, check the
following before MIL troubleshooting.
• Before starting the inspection, check for loose or
poor contact on the sensor unit 5P (Black) and
ECM 33P (Black) connectors.
1. Sensor Unit Power Input Voltage Inspection 1
Connect the test harness 33P to the ECM 33P
(Black) connector (page 6-17).
Turn the ignition switch ON and engine stop
switch " ".
Measure the voltage at the test harness termi-
nals.
Is the voltage within 4.75 – 5.25 V?
YES – GO TO STEP 2.
NO – Replace the ECM with a known good
one, and recheck.
2. Sensor Unit Power Input Voltage Inspection 2
Turn the ignition switch OFF.
Disconnect the sensor unit 5P (Black) connector.
Turn the ignition switch ON and engine stop
switch " ".
Measure the voltage at the wire side.
Is the voltage within 4.75 – 5.25 V?
YES – Turn the ignition switch OFF. Connect
the sensor unit 5P (Black) connector and
start the MIL troubleshooting (page 6-
48).
NO – GO TO STEP 3.
3. Sensor Unit Input Voltage Line Open Circuit
Inspection
Check the continuity between the test harness
and sensor unit 5P connector of the wire side.
Is there continuity?
YES – GO TO STEP 4.
NO – • Open circuit in Yellow/red wire
• Open circuit in Green/orange wire
