Unified Control Meter System Description
UNIFIED CONTROL METER
Speedometer, odo/trip meter, tachometer, fuel gauge and water
temperature gauge are controlled totally by unified meter control
unit.
Meter/gauge Operation and Odo/Trip Meter
Segment Check in Diagnosis Mode
DIAGNOSIS FUNCTION
lOdo/trip meter segment can be checked in diagnosis mode.
lMeters/gauges can be checked in diagnosis mode.
HOW TO ALTERNATE DIAGNOSIS MODE
1. Turn ignition switch to ON and change odo/trip meter to
``TRIP A'' or ``TRIP B''.
2. Turn ignition switch to OFF.
3. Turn ignition switch to ON when pushing odo/trip meter
switch.
4. Confirm that trip meter indicates ``000.0''.
5. Push odo/trip meter switch more than three times within 5
seconds.
6. All odo/trip meter segments should be turned on.
NOTE: If some segments are not turned on, unified meter
control unit should be replaced.
At this point, the unified control meter is turned to diagnosis
mode.
7. Push odo/trip meter switch. Indication of each meter/gauge
should be as shown left during pushing odo/trip meter switch
if it is no malfunctioning.
NOTE: It takes about 1 minute for indication of fuel gauge
to become stable.

Detection Function
Symptom Possible cause Repair order
None of the power windows can be
operated using any switch.1. 30A fusible link and circuit
breaker-1
2. Grounds
M1andM54
3. Power window relay
4. Open/short in power window
main switch circuit1. Check 30A fusible link (letter
b, located in fusible
link and fuse box) and circuit breaker-1, located in
fuse block. Turn ignition switch ``ON'' and verify bat-
tery positive voltage is present at terminal
V1of
power window main switch and terminal
V5of sub-
switch.
2. Check grounds
M1andM54.
3. Check power window relay.
4. Check harness between power window relay and
power window main switch for open/short circuit.
Driver side power window cannot
be operated but other windows can
be operated.1. Driver side power window regu-
lator circuit
2. Driver side power window regu-
lator1. Check harness between power window main switch
and power window regulator for open or short circuit.
2. Check driver side power window regulator.
One or some of power window
except driver side power window
cannot be operated.1. Power window sub-switch
2. Passenger side power window
regulator
3. Power window main switch
4. Power window circuit1. Check power window sub-switch.
2. Check power window regulator of malfunctioning
power window.
3. Check power window main switch.
4-1. Check harnesses between power window main
switch and power window sub-switch for open/short
circuit.
4-2. Check harnesses between power window sub-
switch and power window regulator for open/short
circuit.
Passenger power window cannot
be operated using power window
main switch but can be operated by
power window sub-switch.1. Power window main switch 1. Check power window main switch.
Driver side power window auto
function cannot be operated using
power window main switch.1. Power window main switch 1. Check power window main switch.
