2. Disconnect actuator harness
connector from engine ECU.
Place ignition swtich in ON
position.
3. Measure
voltage
from
actuator harness connector
pin 33 to engine block
ground. Voltage should be
less than 1.5V.
If voltage is not as specified,
proceed with the following
steps.
4. Place ignition switch in OFF
position, disconnect actuator
harness
connector
from
engine ECU, and disconnect
actuator wire from fuel
shutoff solenoid.
5. Measure resistance from
actuator harness connector
pin 33 to all other pins in
connector. Resistance should
be greater than 100k ohms.
If resistance is not as specified,
notify SRA to replace engine
harness.
<1.5V
