UNIFIED METER AND A/C AMP
Revision: 2007 April2007 M35/M45
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionNKS003UG
For the unified meter and A/C amp., the signal required for controlling the combination meter are integrated in
the A/C auto amp.
COMBINATION METER CONTROL FUNCTION

Unified meter and A/C amp. inputs necessary information for combination meter from each unit with CAN
communication and so on.

LANE DEPARTURE WARNING SYSTEM
Revision: 2007 April2007 M35/M45
NOTE:

When a DTC is detected, the LDW system dose not operate.

When the DTC except “ABNRML TEMP DETECT [C1B03] ” is detected, the LDW indicator lamp turns ON.

When the DTC “ABNRML TEMP DETECT [C1B03] ” is detected, the LDW system ON indicator lamp blinks.
DATA MONITOR
Operation Procedure
1. Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.
2. Touch any of “ALL SIGNALS” and “SELECTION FROM MENU” on selection screen.
3. Touch “START”.
4. Display the data monitor.
5. If necessary, touch “COPY” in turn, and print data.
