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
