System Description INFOID:0000000004306997
UNIFIED METER CONTROL UNIT • Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter.
• Warning and indicator lamps are controlled by signal s drawn from the CAN communication system, BCM
(body control module), and components connected directly to the combination meter.
• Odo/trip meter and A/T indicator (with A/T) or CVT i ndicator (with CVT) segments can be checked in self-
diagnosis mode.
• Meters/gauges can be checked in self-diagnosis mode.
POWER SUPPLY AND GROUND CIRCUIT Power is supplied at all times
• through 10A fuse [No. 13, located in the fuse block (J/B)]
• to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 14, located in the fuse block (J/B)]
• to combination meter terminal 28.
Ground is supplied
• to combination meter terminals 21, 22 and 23
• through grounds M57 and M61. 1. Combination meter M24 2. ECM E16 3. ABS actuator and electric unit (con-
trol unit) E33

Engine Speed Signal Inspection INFOID:0000000004307009
Symptom: Improper tachometer indication. OK >> Perform ECM self-diagnosis. Refer to
EC-604, " CONSULT-III Function (ENGINE) " with (MR
TYPE 1), EC-1116, " CONSULT-III Function (ENGINE) " (MR TYPE 2) or
EC-103, " CONSULT-III

NG >> Replace combination meter. Refer to IP-12, " Removal and Installation " .
Fuel Level Sensor Signal Inspection INFOID:0000000004307010
Symptom:
• Improper fuel gauge indication.
• Low-fuel warning lamp indication is irregular.
NOTE:
The following symptoms do not indicate a malfunction.
• Depending on vehicle position or driving circumstance, the fuel level in the tank shifts and the indication may
fluctuate.
• If the vehicle is fueled with the ignition switch ON, the indication will update slowly.
• If the vehicle is tilted when the ignition switch is turned ON, fuel in the tank may flow to one direction result-
ing in a change of reading.

Electrical Component Inspection " .
OK or NG OK >> Check fuel level sensor unit installation, and c
heck whether the float arm interferes or binds with
any of the internal components in the fuel tank. Repair or replace malfunctioning part, if neces-
sary.
NG >> Replace fuel level sensor unit.
Fuel Gauge Fluctuat es, Indicates Wrong Value, or Varies INFOID:0000000004307011YES >> The pointer fluctuation may be caused by fuel
level change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis.
Fuel Gauge Does Not Mo ve to Full-position INFOID:0000000004307012YES >> GO TO 2.
NO >> GO TO 3. YES >> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time to move
to FULL position because of the c haracteristic of the fuel gauge.
NO >> GO TO 3. YES >> Check the fuel level indication with vehicle on a level surface.
NO >> GO TO 4. YES >> Check the components. Refer to
DI-19, " Electrical Component Inspection " .
NO >> The float arm may interfere or bind with any of the components in the fuel tank.
