SHIFT-UP INDICATOR

Shift-up indicator can be used when shifting up at a constant
engine speed from any gear while driving. It becomes a guide
for shift-up timing.

Shift-up indicator flashes approximately 500 rpm before reach-
ing the engine speed set. It illuminates when reaching the
engine speed set.
Shift-up engine speed can be set by the shift-up indicator setting
mode on trip computer. Refer to DI-29, "
Shift-up Indicator Setting
Mode" .
NOTE:

There may be a time lag between the shift-up indicator illumina-
tion and the tachometer indication.

If the battery cable is disconnected, the set engine speed becomes 7,000 rpm.

UNIFIED METER AND A/C AMP
Revision: 2006 November2007 350Z
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionNKS0006X
DESCRIPTION

For the unified meter and A/C amp., the signal required for con-
trolling the combination meter and triple meter are integrated in
the A/C auto amp.

Unified meter and A/C amp. corresponds a CONSULT-III func-
tion (self-diagnosis results, CAN diagnosis support monitor and
data monitor).
COMBINATION METER CONTROL FUNCTION

Unified meter and A/C amp. receives necessary information for combination meter from each unit.

Unified meter and A/C amp. converses with the combination meter transmits a signal through with com-
munication line (TX, RX) between unified meter and A/C amp. and combination meter.
Input/output signals between unified meter and A/C amp. and combination meter.
NOTE:
Combination meter performs fail-safe operation when unified meter and A/C amp. communication is malfunctioning. Refer to DI-7,
"FAIL-SAFE" .
