Inspection Procedure 5

INSPECTION PROCEDURE 5: The Compass can not be Calibrated Manually, or Goes Out of Calibration Easily. [Vehicles with TYPE 1]

TECHNICAL DESCRIPTION (COMMENT)

The compass sensor, which measures the direction of the vehicle, is incorporated in the multi-center display unit. 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 is defective
- Magnetization of vehicle body
- Calibration in magnetized environment (such as factory or a high voltage conductor)

DIAGNOSIS

STEP 1. Check of the display.





Q. Is "EE" displayed?

YES Replace multi-center display unit 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 location is not magnetized strongly.





(2)Set the manual calibration, and drive the vehicle in a circle (Refer to Compass Calibration).

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 Vehicle Magnetic Compensation.

Q. Is the demagnetization performed successfully?

YES Go to Step 4.
NO Replace multi-center display unit 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 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 and then go to Step 1.
