SELF-DIAGNOSIS RESULTS

Self-diagnosis results
YAW RATE SENOR
SIDE G-SENSOR CIRCUIT

CAUTION: If vehicle is on turn-table 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. And after doing spin turns or acceleration turns with VDC function is off (VDC OFF switch "ON"), too, the results will return to a normal state by re-starting vehicle.

Is above displayed in the self-diagnosis display item?

YES: GO TO 2.
NO: INSPECTION END.

CHECK CONNECTOR
1. Disconnect Yaw rate/Side G sensor connector and VDC/TCS/ABS control unit connector and check terminals for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or replace terminal.
2. Reconnect connectors and re-perform a VDC/TCS/ABS control unit self-diagnosis.
OK or NG
1. OK: Connector terminal contact is loose, damaged, open or shorted.
2. NG: GO TO 3.
CHECK YAW RATE/SIDE G SENSOR HARNESS
1. Turn ignition switch OFF and disconnect yaw rate/side G sensor connector and VDC/TCS/ABS control unit connector.
2. Check continuity between VDC/TCS/ABS control unit harness connector E218 and yaw rate/side G sensor harness connector M99.

OK or NG
1. OK: GO TO 4.
2. NG: Open or short in harness. Repair or replace suspect harness.

DATA MONITOR CHECK

Check "DATA MONITOR" for yaw rate /side G sensor. Check that results are normal.

YAW RATE /SIDE G SENSOR DATA MONITOR CHECK

Vehicle condition	Yaw rate sensor (Data monitor standard)	Side G sensor (Data monitor standard)
Stopped	Approx. 0 deg/s	Approx. 0 m/s ²
Turning right	Negative value	Negative value
Turning left	Positive value	Positive value

OK or NG

OK: Perform VDC/TCS/ABS control unit self-diagnosis again.
NG: Malfunction of yaw rate/side G sensor. Replace sensor and perform VDC/TCS/ABS control unit self-diagnosis again.
