OBD / TACH
NOTE: Read this section for non-hybrid vehicles where the
tach was obtained through OBD-II.
After selecting the OBD / TACH option in the previous
screen, TACH is displayed, along with the following:
•
Idling – the vehicle engine rpm reading
NOTE:
•
If the Idling rpm reading is lower than the Idle Point
rpm value on the second line, Stopped will be displayed
instead of Idling.
•
If the Idling rpm reading is higher than the Run Point
rpm value on the third line, Running will be displayed
instead of Idling.
•
If the rpm reading on the first line is not set to Idling,
check ECU OBD-II connection.
•
If the problem continues, obtain the tach signal from
a location under the hood. Refer to section 13.0 and
14.6 of this manual. The ECU and HS may need to be
exchanged.
•
Idle Point – a preset rpm threshold value
•
Run Point – a preset rpm threshold value
NOTE: The initial Idle Point and Run Point values may vary,
depending on the vehicle.
1. Check that the Idling rpm reading reflects the reading on
the dashboard rpm gauge.
2. If the Idling rpm reading is acceptable, press Set Tach to
reset the rpm thresholds.
NOTE: After Set Tach is pressed, the Idling rpm reading (on
the first line) is used to reset the Idle Point and Run Point tach
thresholds (the second and third lines).
TACH is displayed, along with the following:
•
Idling – the vehicle engine rpm reading
•
Idle Point – reset to 0.5 x the Idling engine rpm
•
Run Point – reset to 1.5 x the Idling engine rpm
