COMBINATION METERS
Revision: 2005 July 2005 FX
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER
The vehicle speed signal and the memory signals from the meter memory circuit are processed by the
combination meter and the mileage is displayed.
Switch modes with following procedure.
When trip transfer switch is pressed, trip meter display changes.
If trip reset switch is pressed for 1 second or more while trip A is
displayed, only trip A is reset. (Trip B operates the same way.)
If the battery is disconnected, odometer mileage will be retained
but the trip meter is reset to 0.0.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
through 10A fuse [No. 19, located in the fuse block (J/B)]
to combination meter terminal 8, and
to unified meter and A/C amp. terminal 21.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 14, located in the fuse block (J/B)]
to combination meter terminal 7,
through 10A fuse [No. 12, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 22.
With the ignition switch in the ACC or ON position, power is supplied
through 15A fuse [No. 10, located in the fuse block (J/B)], and
through 15A fuse [No. 11, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 46.
Ground is supplied
to combination meter terminals 5, 6 and 15
through grounds M35, M45 and M85,
to unified meter and A/C amp. terminals 29 and 30
through grounds M35, M45 and M85.

SELF-DIAGNOSTIC RESULTS
Operation Procedure
1. Touch “SELF-DIAG RESULTS” on “SELECT DIAG MODE” screen.
2. Self-diagnosis results are displayed.
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:
“TIME” keeps showing “0” after returning to normal condition only in the case that malfunction his-
tory of “CAN COMM CIRC [U1000]” remains because of low tire pressure warning control unit, display
control unit (with NAVI) or display unit (without NAVI) malfunction.
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 SIG- NALS” is selected, main items will be monitored.

Components Description
NOTE:
*: This indicates in a few seconds for the system check during ignition switch ON.
POWER SUPPLY AND GROUND CIRCUIT
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 12, located in the fuse block (J/B)]
to LDW camera unit terminal 1.
Ground is supplied
to LDW camera unit terminals 6 and 12
through grounds M45, M85 and M35.
CAN CommunicationAKS00C6X
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with two
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
SKIB1784E
Component Description
LDW camera unit Detects the lane marker by the built-in camera, gives judgement for the warning according to the
result of detection and signals from each unit, and transmits the operation signal to LDW chime and
LDW indicator lamp.
LDW switch
Selects ON/OFF of the system.
Indicates ON/OFF of the signal with LDW system ON indicator.
LDW chime Gives a warning chime according to the direction from LDW camera unit.
LDW indicator lamp Installed in combination meter, and indicates the system condition.
Blinks when LDW system is functioning to alert the driver.
Stays on when LDW system is malfunctioning.*
BCM Transmits turn indicator signal to LDW camera unit with CAN communication signal.
ABS actuator and electric unit
(control unit) Transmits vehicle speed signal to LDW camera unit with CAN communication signal.
TCM Transmits vehicle speed signal to LDW camera unit with CAN communication signal. (For detecting
incorrect speed.)
