Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Combined Sensor Inspection
- Turn the ignition switch off.
- Connect the M-MDS to the DLC-2.
- Select the following PIDs, then inspect the lateral acceleration speed and the yaw rate.
- LAT_ACCL: (lateral acceleration speed)
- YAW_RATE: (yaw rate)
- Lateral acceleration speed inspection
- 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.
- Verify the LAT_ACCL change when the combined sensor is tilted to the left and right.
- Yaw rate inspection
- 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.
- Verify the YAW_RATE change when the combined sensor is rotated to the left and right.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
