Acceleration/Deceleration Sensor: Testing and Inspection
COMBINED SENSOR INSPECTION
1. Turn the ignition switch to the LOCK position.
2. Connect the M-MDS to the DLC-2.
3. Select the following PIDs, then inspect the lateral acceleration speed and the yaw rate.
-
LAT_ACCL: (lateral acceleration speed)
-
YAW_RATE: (yaw rate)
a. Lateral acceleration speed inspection
i.
Verify the LAT_ACCL change when the combined sensor is tilted to the left and right.
-
If there is any malfunction, replace the combined sensor.
Standard
-
When the sensor is tilted to the right (A):
LAT_ACCL changes negatively.
-
When the sensor is tilted to the left (B):
LAT_ACCL changes positively.
b. Yaw rate inspection
i.
Verify the YAW_RATE change when the combined sensor is rotated to the left and right.
-
If there is any malfunction, replace the combined sensor.
Standard
-
When the sensor is rotated to the right (A):
YAW_RATE changes negatively.
-
When the sensor is rotated to the left (B):
YAW_RATE changes positively.
