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

CONSULT-III display Malfunction Reference page
CAN COMM CIRC [U1000] Malfunction is detected in CAN communication lines.
CAUTION:
Even when there is no malfunct ion on CAN communication system, mal-
function may be misinterpreted when battery has low voltage (when main-
taining 7 - 8 V for about 2 seconds) or 10A fuse [No. 14, located in the fuse
block (J/B)] is removed. DI-18VEHICLE SPEED CIRC [B2205]
Malfunction is detected when an erroneous speed signal is input.
CAUTION:
Even when there is no malfunction on speed signal system, malfunctions
may be misinterpreted when battery has low voltage (when maintaining 7
- 8 V for about 2 seconds). DI-15Display item [Unit]
