Meter/Gauge Operation and Odo/Trip Meter Segment Check in Diagnosis Mode
EKS0030M
DIAGNOSIS FUNCTION
●Odo/trip meter segment can be checked in diagnosis mode.
●Meters/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
with odo/trip meter 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 a few seconds for indication of fuel gauge and
water temperature gauge to become stable.
Trouble DiagnosesEKS0030N
PRELIMINARY CHECK
1. CHECK WARNING LAMPS
1. Turn ignition switch ON.
2. Warning lamps should illuminate (seat belt warning or door warning etc.).
Do warning lamps illuminate?
Yes >> GO TO 2.
No >> Power supply and ground circuit check. Refer to DI-32, "
Power Supply and Ground Circuit Check"
.
2. CHECK DIAGNOSIS MODE OPERATION
Preform diagnosis mode. Refer to DI-30, "
Meter/Gauge Operation and Odo/Trip Meter Segment Check in
Diagnosis Mode" .
Can diagnosis mode be activated?
Yes >> GO TO 3.
No >> Power supply and ground circuit check. Refer to DI-32, "
Power Supply and Ground Circuit Check"
.

SYMPTOM CHART
Power Supply and Ground Circuit CheckEKS0030O
1. POWER SUPPLY CIRCUIT CHECK
OK or NG
OK >> GO TO 2.
NG >> Check the following:
●10A fuse [No. 11, located in fuse block (J/B)]
●10A fuse [No. 28, located in fuse block (J/B)]
●Harness for open or short between fuse and combination meter
2. GROUND CIRCUIT CHECK
OK or NG
OK >> Inspection end.
NG >> Repair harness or connector.
Symptom Possible cause Repair procedure
Fuel warning lamp is
malfunctioning.
1. Sensor Signal
–Engine revolution signal
–Fuel gauge
–Water temp gauge
2. Unified meter control unit 1. Check the sensor for malfunctioning meter/gauge.
–Inspection/Engine Speed Signal (Refer to DI-33, "Inspection/
Engine Speed Signal" )
–Inspection/Fuel Level Sensor Unit (Refer to DI-37, "Inspection/
Fuel Level Sensor Unit" )
–Inspection/Water Temperature Gauge (Refer to DI-33, "Inspec-
tion/Water Temperature Gauge/Gasoline Engine Models" or DI-
35, "Inspection/Water Temperature Gauge/Diesel Engine Mod-
els" )
2. Replace combination meter One of tachometer/fuel
gauge/water temp. gauge is
malfunctioning.
Speedometer and odo/trip
meter is malfunctioning.1. Sensor Signal
–Vehicle speed signal
2. Unified meter control unit 1. Check the sensor for malfunctioning meter/gauge.–Inspection/Vehicle Speed Signal (Refer toDI-35, "Inspection/
Vehicle speed signal" )
2. Replace combination meter
Multiple meter/gauge are
malfunctioning.
●Unified meter control unit●Replace combination meter.

Inspection/Engine Speed SignalEKS0030P
1.CHECK ECM OUTPUT
1. Start engine.
2. Check voltage between combination meter harness connector
M45 terminals 41 (L/OR) and ground at idle and 2,000 rpm.
OK or NG
OK >> Engine speed signal is OK.
NG >> Check harness for open or short between ECM and
combination meter.
Inspection/Water Temperature Gauge/Gasoline Engine ModelsEKS0030Q
1.CHECK ECM OUT PUT
1. Disconnect combination meter
2. Check Voltage between combination meter harness connector
M46 terminal 66 (PU/W) and ground.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2.CHECK HARNESS FOR OPEN OR SHORT
1. Disconnect ECM connector.
2. Check continuity between combination meter harness connector
M46 terminal 66 (PU/W) and ECM harness connector F43 termi-
nal 32 (PU/W).
3. Check continuity between combination meter harness connector
