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 and inspect the lateral acceleration and yaw rate.
- LAT-ACCL (lateral acceleration)
- YAW - RATE (yaw rate)
(1) Lateral acceleration 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 (A): LAT - ACCL changes positively.
When the sensor is tilted to the left (B): LAT-ACCL changes negatively.

(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 (A): YAW - RATE changes negatively.
When the sensor is rotated to the left (B): YAW-RATE changes positively.
