STEP 8. Check the harness wires between RV meter
connector D-07 (terminal 23 and 31) and ambient air
temperature sensor connector A-29 (terminal 1 and 2).

NOTE: After inspecting intermediate connector D-28 inspect
the wires. If intermediate connector D-28 is damaged, repair or
replace it. Refer to GROUP 00E, Harness Connector Inspec-
tion

P.00E-2

.

Q: Are harness wires between RV meter connector D-07

(terminal 23 and 31) and ambient air temperature sensor
connector A-29 (terminal 1 and 2) in good condition?
YES : Go to Step 9.
NO : Repair or replace them. Refer to GROUP 00E,

STEP 9. Recheck for malfunction.
Q: Is a malfunction eliminated?

YES : 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

P.00-6

.

NO : Replace the RV meter.

INSPECTION PROCEDURE 5: The Compass does not Indicate Normally.

.

TECHNICAL DESCRIPTION (COMMENT)
The geomagnetism sensor integrated in the RV
meter is abnormal, or it is seemed that the indication
is affected by some nearby magnetized matter.

Malfunction of the RV meter

.

DIAGNOSIS

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

P.54A-284

.)

Q: Isn't there any abnormality on the geomagnetism

sensor?
YES : There is no action to be taken.
NO : Step 2.

STEP 2.Check of own vehicle position.
Q: Is the geomagnetism stable at the place?

YES : Go to Step 4.
NO : 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?
YES : There is no action to be taken.
NO : 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?
YES : There is no action to be taken.
NO : Replace the RV meter.

STEP 5. Recheck for malfunction.
Q: Is a malfunction eliminated?

YES : 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

.

NO : Replace the RV meter.
