C1145, C1146 YAW RATE/SIDE G SENSOR
Description
INFOID:0000000003766966
The yaw rate/side G sensor detects the yaw rate/side G affecting the vehicle, and transmits the data to the
ABS actuator and electric unit (control unit) as an analog voltage signal.

DTC REPRODUCTION PROCEDURE
1.
Turn the ignition switch ON.
2.

Diagnosis Procedure
INFOID:0000000003766968
CAUTION:
• Sudden turns (such as spin turns, acceleration turns), drifting, etc., when VDC function is off (VDC
OFF switch “ON”) may cause yaw rate/side G sensor system to indicate a malfunction. However, this
is not a malfunction, if normal operation can be resumed after restarting engine. Then erase memory
of self-diagnosis.
• If vehicle is on turn-table at entrance to parking garage, or on other moving surface, VDC OFF indica-
tor lamp may illuminate and CONSULT-III self-diagnosis may indicate yaw rate sensor system mal-
function. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of
turn-table or other moving surface, and start the engine. Results will return to normal.
