System DescriptionINFOID:0000000001704491
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 signals 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 indicator (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.

Self-Diagnosis Mode of Combination MeterINFOID:0000000001704497
SELF-DIAGNOSIS MODE FUNCTION
• Self-diagnosis can check for continuity between meter control circuit and each meter (speedometer, tachom-
eter and fuel gauge).
• Self-diagnosis can check for odo/trip meter and A/T indicator (with A/T) or CVT indicator (with CVT) seg-
ment, low-fuel level warning lamp, low water temperature indicator lamp, and high water temperature warn-
ing lamp.
OPERATION PROCEDURE
1. Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.

Fuel Level Sensor Signal InspectionINFOID:0000000001704504
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.
