Vehicle Speed Signal InspectionBKS001S8
1. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) SELF-DIAGNOSIS
Perform the ABS actuator and electric unit (control unit) self-diagnosis. Refer to BRC-57, "
CONSULT-II Func-
tions" (with VDC system) or BRC-17, "CONSULT-II Functions (ABS)" (without VDC system).
Self
-diagnostic results content
No malfunction detected>>GO TO 2.
Malfunction detected>>Check applicable parts, and repair or replace corresponding parts.
2. CHECK UNIFIED METER AND A/C AMP. OUTPUT SIGNAL
1. Start engine and drive vehicle at approximately 40 km/h (25 MPH).
2. Check voltage signal between unified meter and A/C amp. har-
ness connector M42 terminal 26 and ground with simple oscillo-
scope of CONSULT-II.
OK or NG
OK >> GO TO 3.
NG >>

If monitor indicates “0V” constantly, repair or replace malfunctioning parts after checking each
unit inputting vehicle speed signal (8 pulse), harness and connector between each unit and uni-
fied meter and A/C amp.

If monitor indicates “5V” or “12V” constantly, replace unified meter and A/C amp. Refer to DI-34,
"Removal and Installation of Unified Meter and A/C Amp." .
3. CHECK CONTINUITY BETWEEN COMBINATION METER AND UNIFIED METER AND A/C AMP.
1. Turn ignition switch OFF.
2. Disconnect combination meter connector and unified meter and A/C amp. connector.
3. Check continuity between combination meter harness connector
M70 terminal 20 and unified meter and A/C amp. harness con-
nector M42 terminal 26.
OK or NG
OK >> Replace combination meter.
NG >> Repair harness or connector.26 – Ground:NOTE:
Maximum voltage may be
12V due to specifications
(connected units).

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).

DATA MONITOR
Operation Procedure
1. Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.
2. Touch either “MAIN SIGNALS” or “SELECTION FROM MENU” on the “DATA MONITOR” screen.
3. When “SELECTION FROM MENU” is selected, touch individual
items to be monitored. When “MAIN SIGNALS” is selected,
main items will be monitored.
4. Touch “START”.
5. Touch “RECORD” while monitoring, then the status of the moni-
tored item can be recorded. To stop recording, touch “STOP”.
Display Item List
