COMBINATION METERS
System DescriptionINFOID:0000000001328433
UNIFIED METER CONTROL UNIT
 Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the comb ination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.
 Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified meter and A/C amp.
 Odo/trip meter, A/T indicator and ICC system disp lay segments can be checked in self-diagnosis mode.
 Meters/gauges can be checked in self-diagnosis mode.
UNIFIED METER AND A/C AMP.
Refer to DI-26, "System Description" in “UNIFIED METER AND A/C AMP”.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
 through 10A fuse [No. 19, located in the fuse block (J/B)]
 to combination meter terminal 8, and
 to unified meter and A/C amp. terminal 21.
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 7,
 through 10A fuse [No. 12, located in the fuse block (J/B)]
 to unified meter and A/C amp. terminal 22.
With the ignition switch in the ACC or ON position, power is supplied
 through 10A fuse [No. 6, located in the fuse block (J/B)]
 to combination meter terminal 4,
 through 15A fuse [No. 10, located in the fuse block (J/B)], and
 through 15A fuse [No. 11, located in the fuse block (J/B)]
 to unified meter and A/C amp. terminal 46.
Ground is supplied
 to combination meter terminals 5, 6 and 15
 through grounds M35, M45 and M85,
 to unified meter and A/C amp. terminals 29 and 30
 through grounds M35, M45 and M85.
SPEEDOMETER
The speedometer indicates the vehicle speed.
 ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. converts the vehicle s peed signal to the 8-pulse signal, and outputs the vehicle
speed signal (8-pulse) to combination meter.
 Combination meter indicates the vehicle speed according to vehicle speed signal (8-pulse) signal.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
 ECM provides engine speed signal to unified meter and A/C amp. with CAN communication.
 Unified meter and A/C amp. transmits engine speed signal to combination meter with communication line.

3. Turn ignition switch ON while pressing trip transfer switch and trip reset switch at the same time.
4. After ignition switch is turned ON, release trip transfer switch and trip reset switch (within 7 seconds after the ignition switch is
turned ON).
5. All the segments on the odo/trip meter, A/T indi cator and ICC system display illuminates, and simulta-
neously the low-fuel warning lamp indicator illuminates. At this time, the unified meter control unit is turned
to self-diagnosis mode.
NOTE:
 Check odo/trip meter switch and combination meter power supply and ground circuit when self-diagno-
sis mode of combination meter does not start. Replace combination meter if the results of the check are
normal.
 If any of the segments are not disp layed, replace combination meter.
6. Each meter/gauge activates during pressing trip reset switch. (Then low-fuel warning lamp turns OFF.)
NOTE:
 If any of the meters/gauges are not activated, replace thecombination meter.
