Inspection Procedure 6

INSPECTION PROCEDURE 6: The Compass Can Not Be Calibrated Manually, Or Becomes Out Of Calibration Easily (Middle Grade Type)

TECHNICAL DESCRIPTION (COMMENT)
The compass sensor, which measures the direction of the vehicle, is incorporated in the multi-center display unit (middle grade type). If the direction of the vehicle is not displayed normally by repeating the manual calibration, the compass sensor may be defective, the vehicle body may have been magnetized, or the manual calibration is performed in strongly magnetized environment.

TROUBLESHOOTING HINTS
- The compass sensor in the multi-center display unit (middle grade type) is defective
- Magnetization of vehicle body
- Calibration in magnetized environment (such as factory or a high voltage conductor)

DIAGNOSIS

STEP 1. Check the compass sensor by using a self-diagnostic function.






Start up the service mode to check the compass.

Q: Is "NG" displayed as the check result for the compass sensor?

YES : Replace multi-center display unit (middle grade type) and then go to step 5.

NO : Go to Step 2.

STEP 2. Confirm if the manual calibration is performed successfully.

1. Park the vehicle on an open space, and confirm that the place is not magnetized strongly.




2. Set the manual calibration, and drive the vehicle in a circle.

Q: Is the manual calibration performed successfully?

YES : Go to Step 5.

NO : Go to Step 3.

STEP 3. Demagnetize the vehicle.

In certain circumstances the vehicle body may be magnetized. For how to demagnetize, refer to P.54A-309.

Q: Is the demagnetization performed successfully?

YES : Go to Step 4.

NO : Replace multi-center display unit (middle grade type) and go to step 4.

STEP 4. Perform the manual calibration again.

Q: Is the manual calibration performed successfully?

YES : Go to Step 5.

NO : Replace multi-center display unit (middle grade type) and then go to Step 1.

STEP 5. Retest the system.

Q: Is the check result satisfactory?

YES : The procedure is complete.

NO : Replace multi-center display unit (middle grade type) and then go to Step 1.
