3. PREVIOUS TROUBLE CODE READING
1) Connect select monitor.
2) Designate mode using function key.
Press [F] [B] [1] [ENT] in that order.
3) Ensure displayed trouble code(s).
USING AN OSCILLOSCOPEA malfunction can be determined by displaying the waveforms
of input/output signals on the oscilloscope.
Diagnosis
A simple comparison of the waveforms may lead to an incor-
rect diagnosis. To exactly determine the sources of the mal-
function it will be necessary to determine them under consider-
ation about information other than waveforms.
Applying input/output signals
Connect the probe directly with the terminal of the signal.
