The Error History displays the time and place of the most recent occurrence of that error. However, take note
of the following points.
• Correct time of the error occurrence may not be displayed when the GPS antenna substrate within the NAVI
control unit has malfunctioned.
• Place of the error occurrence is represented by the position of the current-location mark at the time when the
error occurred. If the current-location mark has deviated from the correct position, then the place of the error
occurrence may be located correctly.
• The maximum number of occurrences which can be stored is 50. For the 51st and later occurrences, the dis-
played number remains 50.
When a reproducible malfunction occurred but its cause cannot be identified because several errors are
present, record the item, number and place (longitude/latitude) of error occurrence (or delete the Error His-
tory), then turn the ignition switch from OFF to ON to reproduce the malfunction. Check the Error History to
find the items which show an increased number of occurrences, and diagnose the item.

COMBINATION METERS
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.
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 24.
Ground is supplied
• to combination meter terminal 17
• through body grounds M57, M61 and M79.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to combination meter via CAN communication lines.
ENGINE OIL PRESSURE GAUGE
The engine oil pressure gauge indicates whether the engine oil pressure is low or normal.
The oil pressure gauge is controlled by the IPDM E/R (intelligent power distribution module engine room). Low
oil pressure causes oil pressure switch terminal 1 to provide ground to IPDM E/R terminal 42. The IPDM E/R
then signals the combination meter (unified meter control unit) via CAN communication lines and a low oil
pressure indication is displayed by the oil pressure gauge.
A/T OIL TEMPERATURE GAUGE
The A/T oil temperature gauge indicates the A/T fluid temperature.
TCM (transmission control module) provides an A/T flui d temperature signal to combination meter via CAN
communication lines.
VOLTAGE GAUGE
The voltage gauge indicates the battery/charging system voltage.
The voltage gauge is regulated by the unified meter control unit.
TA C H O M E T E R
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM provides an engine speed signal to combination meter via CAN communication lines.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by the unified meter control unit and a variable resistor signal supplied
• to combination meter terminal 15.
• through fuel level sensor unit and fuel pump terminal 2
• through fuel level sensor unit and fuel pump terminal 5
• from combination meter terminal 16
SPEEDOMETER
ABS actuator and electric unit (contro l unit) provides a vehicle speed signal to the combination meter via CAN
communication lines.
ODO/TRIP METER
The vehicle speed signal and the memory signals from the meter memory circuit are processed by the combi-
nation meter and the mileage is displayed.
How to Change the Display
Refer to Owner's Manual for odo/tr ip meter operating instructions.

Ground is supplied
• to sonar control unit terminal 6
• through body grounds B7 and B19.
With the ignition switch in the ON or START position, and the transmission gear selector lever in the R posi-
tion, power is supplied
• to sonar control unit terminal 5
• from back-up lamp relay terminal 5.
With power and ground supplied, transmission gear selector lever in R position, and the rear sonar system
OFF switch ON, the rear sonar system will detect obstacles within 1.8 m (5.9 ft.) of the rear sonar sensors. The
vehicle operator is notified of obstacles by varied rate of tone from the sonar buzzer depending on distance of
obstacle being sensed.
REAR SONAR SYSTEM OFF SWITCH
With power and ground supplied to the sonar control unit, transmission gear selector lever in R position, the
sonar system can be disabled and the sonar buzzer silenced by momentarily pressing the rear sonar system
OFF switch. The rear sonar system OFF indicator lamp will be illuminated in the rear sonar system OFF
switch.
To disable the rear sonar system, ground is supplied
• to sonar control unit terminal 13
• through rear sonar system OFF switch terminal 1
• through rear sonar system OFF switch terminal 2
• from body grounds M57, M61, and M79.
To light the rear sonar system OFF indicator, power is supplied
• from sonar control unit terminal 4
• to the rear sonar system OFF switch terminal 5.
Ground is supplied
• to the rear sonar system OFF switch terminal 6
• from body grounds M57, M61, and M79.
The rear sonar system and buzzer will be disabled and the rear sonar system OFF indicator will be illuminated
until the ignition switch is turned OFF. When the ignition switch is turned ON, the rear sonar system will be
enabled. Depressing the rear sonar system OFF switch momentarily will enable the rear sonar system also.
Enabling the rear sonar system will cause the rear sonar system OFF indicator to go out.
SONAR BUZZER
With power supplied to the sonar control unit and the transmission gear selector lever in R position, a station-
ary object that is at least 7.0 cm (2.8 in.) wide and 1.0 m (39.0 in.) tall and that is closer than 1.8 meters (5.9 ft.)
will be detected by the rear sonar sensors, causing the sonar buzzer to sound a tone. As the vehicle moves
closer to the object, the rate of the tone will increase. When the object is less than 25.0 cm (10 in.) from the
rear bumper, the tone will sound continuously.
Power is supplied
• from sonar control unit terminal 7
• to sonar buzzer terminal +.
Ground is supplied
• to sonar buzzer terminal -
• from sonar control unit terminal 3.
REAR SONAR SENSOR
With power and ground supplied to the rear sonar sensors, the sonar sensors transmit a 38.4 kHz ultrasonic
signal. This signal is reflected back to the sensor by objects large enough and close enough to be detected.
The rear sonar sensors measure the time from the transmitted signal to the time the signal is reflected back
and sends this information to the sonar control unit.
Power is supplied
• from sonar control unit terminal 16
• to each rear sonar sensor terminal 1.
Ground is supplied
• to each rear sonar sensor terminal 3
• from sonar control unit terminal 15.
Signal is supplied
• from each rear sonar sensor terminal 2
• to sonar control unit terminals 9, 10, 11 and 12.
