COMBINED SENSOR INSPECTION

1. Turn the ignition switch off.

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.
