Adjustment of Steering Angle Sensor Neutral PositionAFS001S9
In case of doing work that applies to the list below, make sure to adjust neutral position of steering angle sen-
sor before running vehicle.
× : Required
–: Not required
CAUTION:
To adjust neutral position of steering angle sensor, make sure to use CONSULT-II.
(Adjustment can not be done without CONSULT-II.)
1. Stop vehicle with front wheels in straight-ahead position.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector on vehicle, and turn ignition switch ON (do not start engine).
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.
3. Touch “ABS”, “WORK SUPPORT” and “ST ANGLE SENSOR ADJUSTMENT” on CONSULT-II screen in this order. Refer to BRC-26, "
CONSULT-II BASIC OPERATION PROCEDURE" .
4. Touch “START”. CAUTION:
Do not touch steering wheel while adjusting steering angle
sensor.
5. After approximately 10 seconds, touch “END”. (After approxi- mately 60 seconds, it ends automatically.)
6. Turn ignition switch OFF, then turn it ON again. CAUTION:
Be sure to perform above operation.
7. Run vehicle with front wheels in straight-ahead position, then stop.
8. Select “DATA MONITOR”, “SELECTION FROM MENU”, and “STR ANGLE SIG” on CONSULT-II screen. Then make sure “STR ANGLE SIG” is within 0 ±3.5 deg. If value is more than specification, repeat steps 3
to 7.
9. Erase memory of ABS actuator and electric unit (control unit) and ECM.
10. Turn ignition switch OFF.
Calibration of Decel G Sensor (AWD Model)AFS001TQ
NOTE:
After removing/installing or replacing yaw rate/side/decel G sensor, ABS actuator and electric unit (control
unit), suspension components, or after adjusting wheel alignment, make sure to calibrate of decel G sensor
before running vehicle.
CAUTION:
To calibrate decel G sensor, make sure to use CONSULT-II. (Adjustment can not be done without CON-
SULT-II.)

turned on. Make that ABS warning lamp turned off while driving vehicle at approximately 30 km/h (19 MPH) or
more for approximately 1 minute according to self-diagnosis procedure. In addition, if wheel sensor 2 is dis-
played for wheels, check wheel sensor circuit and also check ABS actuator and electric unit (control unit)
power voltage.

CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc. may cause the G sensor circuit

restarting engine.
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
CAUTION:
When on a turntable, such as at a parking structure entrance, or when on a moving object with engine
running, VDC OFF indicator lamp might turn on and self-diagnosis using CONSULT-II the yaw rate sen-
sor system might be displayed, but in this case there is no malfunction in yaw rate sensor circuit. As
soon as vehicle leaves turntable or moving object, restart engine to return the system to normal.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK CONNECTOR
1. Disconnect G sensor connector and ABS actuator and electric unit (control unit) connector and check ter- minals for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace
terminal.
2. Reconnect connectors and perform a ABS actuator and electric unit (control unit) self-diagnosis again.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 3.

UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.

Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.

Digital meter is adopted for odo/trip meter*.
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.

Odo/trip meter, A/T indicator and ICC system display segments can be checked in diagnosis mode.

Meters/gauges can be checked in diagnosis mode.
Illumination Control
The unified meter control unit outputs the odo/trip meter and A/T
indicator lighting when the ignition switch is turned on. When the
lighting switch is turned on, light on for the combination meter dial,
illumination control switch and external lighting are output. In addi-
tion, when the lighting switch is turned on, the illumination control
switch on the left side of the combination meter can be used to
adjust the brightness of each light. The brightness can be adjusted
to sixteen different levels: From 0 (no lights) to 15 (maximum).
Pressing the illumination control switch will brighten or darken the
lights. When the ignition switch is in the START position, the combi-
nation meter dial lighting and illumination control switch lighting are
turned off.

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

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)]
