3) Turn ignition switch and select monitor switch ON.
4) After display is shown, press slash“/”key.
5) After AT mode is displayed, press function“[0]”.
(Display returns to AT mode when slash“/”is pressed during
on-board diagnostic operation.)

4. READ TROUBLE CODE SHOWN ON DISPLAY.
1) Connect select monitor.
2) Designate mode using function key.
Press [F] [B] [0] [ENT] in that order.
3) Ensure trouble code(s) is shown.

5. 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).
C: USING AN OSCILLOSCOPE
A malfunction can be determined by displaying the waveforms
of input/output signals on the oscilloscope.
1. 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 consid-
eration about information other than waveforms.
2. APPLYING INPUT/OUTPUT SIGNALS
Connect the probe directly with the terminal of the signal.
