UNIFIED METER AND A/C AMPPFP:27760
System DescriptionBKS001SK
For the unified meter and A/C amp., the signal required for con-
trolling the combination meter are integrated in the A/C auto
amp.
Unified meter and A/C amp. controls each operation for A/C
auto amp. For information regarding A/C control, refer to AT C -
24, "AIR CONDITIONER CONTROL" .
Unified meter and A/C amp. inputs necessary information for
combination meter from each unit by CAN communication and
so on.
And unified meter and A/C amp. outputs these signals using
communication line (TX, RX) between unified meter and A/C
amp. and combination meter.
The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (with display unit) using CAN communication.
Other input signals are also sent to the ECM, TCM, BCM and display unit (with display unit) using CAN
communication.
The unified meter and A/C amp. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor and data monitor).

CONSULT-II Function (METER A/C AMP)BKS001SO
CONSULT-II performs the following functions communicating with the unified meter and A/C amp.
CONSULT-II BASIC OPERATION
Refer to GI-34, "CONSULT-II Start Procedure"
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.
SELF-DIAGNOSTIC RESULTS
Display Item List
“TIME” indicates the condition of the self-diagnostic results judged by each signal input.
Normal: In case of operating properly at the present in spite of having malfunction in the past, then “TIME”
indicates “1-63”.
Malfunction: Soon after detecting malfunctions by self-diagnoses or current malfunction, “0” is indicated.
After returning to normal condition, every time when ignition switch is turned to “OFF” from “ON”, time will be
added like “1”→“2”→“3”···“63”, and when the key operation is performed 64 times, the result of the self-diag-
noses will be erased. And if any malfunction is detected again, “0” will be indicated.

CAUTION:
Even when there is no malfunction on CAN communication system, malfunction may be
misinterpreted when battery has low voltage (when maintaining 7-8V for about 2 seconds)
or 10A fuse [No. 19, located in the fuse block (J/B)] is disconnected.

CAUTION:
Even when there is no malfunction on speed signal system, malfunction may be misinter-
preted when battery has low voltage (when maintaining 7-8V for about 2 seconds).
