Component Tests and General Diagnostics

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)





(1) Lateral acceleration speed inspection
1) 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: LAT_ACCL changes negatively.
When the sensor is tilted to the left: LAT_ACCL changes positively.





(2) Yaw rate inspection
1) 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: YAW_RATE changes negatively.
When the sensor is rotated to the left: YAW_RATE changes positively.
