9. Select Monitor Function Mode

1) When a trouble code is not stored in memory, activat-
ing the FE mode causes the initial value to appear on the
select monitor display.

FE1—4: 159 mile/h

FE5—8: 255 km/h

FE13: 16.84 V

FE14: 5.00 V

FE15: The MM, B1 and A0 LEDs are on.
The AT and CM LEDs are out.
B4M0920
2) If freeze frame data is not properly stored in memory
(due to a drop in ABSCM power supply, etc.), a trouble
code, preceded by a question mark“?”, appears on the
select monitor display. This shows it may be an unreliable
reading.
3) When a trouble code is detected in the FE mode, a
question mark“?”appears continuously on the select moni-
tor display until the freeze frame data is stored in memory.
4) Freeze frame data and trouble code, stored in memory,
are cleared simultaneously in the FC mode.
