SELF-DIAGNOSIS RESULTS

Self-diagnosis results

YAW RATE SENSOR

SIDE G-SEN CIRCUIT

G-SENSOR

CAUTION: If vehicle is on turntable at entrance to parking garage, or on other moving surface, VDC OFF indicator lamp may illuminate and CONSULT-II self-diagnosis may indicate yaw rate sensor system malfunction. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of turntable or other moving surface, and start engine. Results will return to normal.

Is the above displayed in the self-diagnosis display items?

YES: GO TO 2.
NO: Inspection End.

CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E125 and yaw rate/side/decel G sensor connector B73.

Check the terminals for deformation, disconnection, looseness or damage.

OK or NG
- OK: GO TO 3.
- NG: Repair or replace as necessary.

YAW RATE/SIDE/DECEL G SENSOR HARNESS INSPECTION

Turn off the ignition switch and disconnect yaw rate/side/decel G sensor connector B73 and ABS actuator and electric unit (control unit) connector E125.

Check continuity between the ABS actuator and electric unit (control unit) connector E125 and the yaw rate/side/decel G sensor connector B73.

ABS actuator and electric unit (control unit) harness connector E125	Yaw rate/side/decel G sensor harness connector B73	Continuity
6	3	Yes
24	5
25	1
29	2

OK or NG

OK: GO TO 4.
NG: Repair or replace as necessary.

YAW RATE/SIDE/DECEL G SENSOR INSPECTION

Connect the yaw rate/side/decel G sensor connector B73 and ABS actuator and electric unit (control unit) connector E125.

Use "DATA MONITOR" to check if the yaw rate/side/decel G sensor signals are normal.

DATA MONITOR STANDARD

When stopped	-4 to +4 deg/s	-1.1 to +1.1 m/s	-0.08 G to +0.08 G
Right turn	Negative value	Negative value	-
Left turn	Positive value	Positive value	-
Speed up	-	-	Negative value
Speed down	-	-	Positive value

OK or NG

OK: Inspection End.
NG: Replace the yaw rate/side/decel G sensor. Refer to "REMOVAL AND INSTALLATION ".
