TROUBLE DIAGNOSIS FOR SYSTEM
1. Disconnect ABS actuator and electric unit (contro
l unit) connector. Then reconnect it securely.
2. Perform self-diagnosis again.
Do any self-diagnosis item appear?
YES >> GO TO 3.
NO >> Poor connection. Repair or replace the applicable connector.
3.CHECK ABS MOTOR AND MOTOR RELAY POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF and disconnect ABS actuat or and electric unit (control unit) connector E56.
2. Check voltage between ABS actuator and electric unit (control unit) harness connector and ground.
3. Check continuity between ABS ac tuator and electric unit (control
unit) harness connector and ground.
OK or NG
OK >> Perform self-diagnosis again. If the same result appears, replace ABS actuator and electric unit (control
unit). Refer to BRC-54
.
NG >> Repair harness or connectors.
DTC C1113 G-SENSORINFOID:0000000001327682
CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc. may cause the G sensor circuit
indicate a malfunction. However, this is not a malf unction, if normal operation can be resumed after
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 wh en on a moving object with engine
running, VDC OFF indicator lamp might turn on and self-diagnosis using CONSULT-III the yaw rate
sensor system might be displayed, but in this case ther e 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

1. Disconnect G sensor connector and ABS actuator and el ectric unit (control unit) connector and check ter-
minals for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace
terminal.

and electric unit (control unit) connector E56.
2. Check continuity between ABS ac tuator and electric unit (control
unit) harness connector and G sensor harness connector.
OK or NG
OK >> GO TO 4.
NG >> If the open or short in harness, repair or replace harness.

COMPASS
COMPASS
Precaution for CompassINFOID:0000000001328520
NOTE:
 Do not install the ski rack, antenna, etc. which is attach to the vehicle with a magnet base. It affects the oper-
ation of the compass.
 When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as it may c ause the liquid cleaner to enter the mirror housing.
System DescriptionINFOID:0000000001328521
 This electronic compass is able to display 8 primary directions: N, NE, E, SE, S, SW, W, NW.
 The inside mirror switch (2) is used to operate the compass and
automatic anti-glare system.
Switch Operation
NOTE:
For further details of the compass and automatic anti-glare system, refer to Owner's Manual
 All standard compasses determine direction relative to Magnetic North; however, this electronic compass is
designed to display direction relative to True North.
 The difference between Magnetic North and True North varies from place to place across the surface of the
earth.
 This electronic compass must be “told” approximately w here it is on the earth’s surface so that the Magnetic
North reading can be properly converted into a True North display.
 To tell the electronic compass where it’s at, the earth is separated into numbered “Zone Variances”. The
Zone Variance number in which the compass is to function must be entered into this electronic compass.
 Each zone is magnetically about 4.2 ° wide. Typically, anything under 22.5 ° total zone change is not noticed
on the electronic compass display. However, over 22.5 °, a reading may be off by one or more primary direc-
tions.
 On long trips, a vehicle may leave its original zone and enter one or more new zones. Generally, you do not need to reset the compass zone if you travel between 3 or 4 zones, such as business travel or vacation. The
typical driver will not notice any difference on the display within 3 or 4 zones. However, if the vehicle is “per-
manently” moved to a new location, it is recommended that the compass zone be reset.
TroubleshootingINFOID:0000000001328522
 The electronic compass is highly protected from changes in most magnetic fields. However, some large changes in magnetic fields can affect it. Some examples are (but not limited to): high tension power lines,
large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While
this does not happen very often, it is possible.
