Inspection Procedure
7: The Compass does not Indicate Normally.
COMMENTS ON TROUBLE SYMPTOM
The geomagnetism sensor integrated in the RV meter is abnormal, or it is seemed that the
indication is affected by some nearby magnetized matter.
PROBABLE CAUSES
Malfunction of the RV meter
DIAGNOSIS PROCEDURE
STEP 1. Check the geomagnetism sensor mode in service mode.
(1)When the adjusting switch is continuously pressed for more than five seconds, the
reception sound (pip sound) is heard and at the same time the service function is activated
to display the service mode screen.
(2)Press the adjusting switch with the ignition switch at the "LOCK" (OFF) position.
Then while keeping the switch on the pressed condition, turn the ignition switch to "ACC" position.
(3)Check the geomagnetism sensor at the geomagnetism sensor mode (Refer to ).
Q.
Isn’t there any abnormality on the geomagnetism sensor?
There is no action to be taken.
Go to Step 2.
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.
Isn’t there any abnormality at the geomagnetism sensor mode?
There is no action to be taken.
Go to Step 4.
STEP 4. Check of RV meter for magnetization.
Q.
Does the indication return to normal when the carrier antenna that is mounted on the
body by a magnet, a magnet or metal existing nearby the RV meter is removed?
There is no action to be taken.
Replace the RV meter, then go to step 5.
STEP 5. Recheck for malfunction.
Q.
Is a malfunction eliminated?
If no malfunctions are not found in all steps, an intermittent malfunction is
suspected. Refer to GROUP 00,How to Use Troubleshooting/Inspection Service Points-How
to Cope with Intermittent Malfunction .
).
There is no action to be taken.
Go to Step 2.
