SIMULATION TEST
34
①
Connect the connecting couplers of O2 sensor and
ECU properly with check harness.
②
Make the O2 sensor test in reference to "Normal
Test" in page 24 to 33.
③
If the sensor type is not sure by a process to the
above, select the zirconia O2 sensor.
※
To select the type of O2 sensor, press SEL Key
for 1 second or less in stand-by mode. (default
setting is zirconia O2 sensor)
※
Simulation test cannot be made for A/F (air-fuel
ratio) sensor.
※
Connect O2 sensor and ECU properly with check
harness before starting the simulation test.
※
An error code might be memorized in ECU and
warning lamp may lights up when simulation test
is made for rear O2 sensor.
Do not make the simulation test for other
purposes except for the checking O2 sensor circuit
and this instrument.
CAUTION
What is simulation test?
Simulation test is the function that outputs the
simulated sensor signal from SK-8402 and check
various defects of O2 sensor and ECU. In combination
with a scanning tool that can monitor the control
condition of ECU or sensor signal waveform, various
checking are possible such as control condition of ECU,
connecting defects of cable connections of O2 sensor
and ECU, or O2 sensor troubles.
