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.
