Combination Meter Calibration
After replacing a combination meter, it might be necessary to cali-
brate the fuel gauge/low fuel warning lamp. In case the fuel warn-
ing lamp is flashing after replacing the combination meter perform
the following:
1. Press both reset buttons.
2. Turn the ignition ONand keep the reset buttons depressed
for at least 5 seconds.
3. Release both reset buttons.
The low fuel warning lamp will stop flashing and the combina-
tion meter will show CALL and possibly CALL FAIL. Showing
CALL FAIL does not indicate a concern as this might be related
to the current (unexpected) amount of fuel in the tank.

cate malfunction in Diagno-
sis mode.
One of speedometer/

cates malfunction in Diag-
nosis mode.1. Meter/Gauge
2. Unified meter control unit1. Check resistance of meter/gauge indicating malfunc-
tion. If the resistance is NG, replace the meter/
gauge.
2. If the resistance of meter/gauge is OK, replace uni-
fied meter control unit.

OK©GO TO 3.
NG©Replace fuel level sensor unit.
3 CHECK HARNESS FOR OPEN OR SHORT
1. Disconnect combination meter connector and fuel level sensor unit connector.
2. Check continuity between combination meter terminal 24 and fuel level sensor unit connector terminal 4.
Continuity should exist.
3. Check continuity between combination meter terminal 24 and ground.
Continuity should not exist.
