Inspection Procedure 5: The compass does not indicate normally.


COMMENTS ON TROUBLE SYMPTOM



  • The compass sensor integrated in the RV meter is abnormal, or it is seemed that the indication is affected by some nearby magnetized matter.
  • The RV meter receives the vehicle speed pulse and checks the vehicle status whether it is travelling or being stopped.
note If the sensor is not normal, the compass is not displayed.

PROBABLE CAUSES



DIAGNOSIS PROCEDURE

STEP 1. Check the RV meter.
Check that the average vehicle speed and the average fuel consumption are displayed normally, and check that the connection with the vehicle speed sensor is normal.

Q. Is the check result satisfactory?
Go to Step 2
Perform the troubleshooting, Inspection Procedure 2: "The drive information is not displayed normally". (Refer to .)

STEP 2.Check of own vehicle position.

Q. Is the geomagnetism stable at the place?

Go to Step 4
Go to Step 3

STEP 3. Move the vehicle to the geomagnetically stable location to re-check the geomagnetism.

Q. Does the compass indicate normal?
There is no action to be taken.
Go to Step 4

STEP 4. Check of compass sensor for magnetisation.


Remove the a magnet or metal existing nearby the compass sensor when the carrier antenna that is mounted on the body by a magnet.

Q. Does the indication return to normal?
There is no action to be taken.
Go to Step 5

STEP 5. Check the declination calibrated value.
In compass setting, check that the initial value of the declination calibrated value is normal. (Refer to RV meter, Compass Setting .)

Q. Is the check result normal?
Go to Step 6
Repair the declination calibrated value, and then go to Step 6.

STEP 6. Carry out the compass calibration and recheck the trouble symptom.
Carry out the compass calibration in the compass setting, and check if the compass display is normal. (Refer to RV meter, Compass Setting .)

Q. Is the check result normal?
The diagnosis is complete.
Go to Step 7

STEP 7. Delete the compass azimuth circle, and recheck the trouble symptom.
Carry out the compass azimuth circle delete in the service mode of the RV meter, and check if the compass display is normal. (Refer to RV meter, Service Mode .)
note After deleting the compass azimuth circle, carry out the declination calibration of the compass setting and the compass calibration.

Q. Is the check result normal?
The diagnosis is complete.
Replace the RV meter
