SYMPTOM CHART
Symptom Chart 1 (Malfunction is Indicated in Diagnosis Mode)
SymptomPossible causes Repair order
Odo/trip meter indicates
malfunction in Diagnosis
mode. Unified meter control unit
Replace unified meter control unit.
Multiple meter/gauge indi-
cate malfunction in Diagno-
sis mode.
One of speedometer/
tachometer/fuel gauge/
water temp. gauge indicates
malfunction in Diagnosis
mode. 1. Meter/Gauge
2. Unified meter control unit
1. Check resistance of meter/gauge indicating malfunction.
If the resistance is NG, replace the meter/gauge.
2. If the resistance of meter/gauge is OK, replace unified- meter control unit.
Symptom Chart 2 (No Malfunction is Indicated in Diagnosis Mode)
Symptom Possible causes Repair order
One of speedometer/
tachometer/fuel gauge/
water temp. gauge is mal-
functioning. 1. Sensor signal
- Vehicle speed signal
- Engine revolution signal
- Fuel gauge
- Water temp. gauge
2. Unified meter control unit 1. Check the sensor for malfunctioning meter/gauge.
INSPECTION/VEHICLE SPEED SENSOR (Refer to
EL-95.)
INSPECTION/ENGINE REVOLUTION SIGNAL (Refer
to EL-96.)
INSPECTION/FUEL LEVEL SENSOR UNIT (Refer to
EL-96.)
INSPECTION/THERMAL TRANSMITTER (Refer to
EL-97.)
2. Replace unified meter control unit.
Multiple meter/gauge are
malfunctioning. (except odo/
trip meter)
Before starting trouble diagnoses below, perform PRELIMINARY CHECK, EL-92.

unit.
CHECK HARNESS FOR OPEN OR
SHORT.
1. Disconnect fuel level sensor unit har-
ness connector and combination meter
harness connector.
2. Check continuity between combination meter terminal 13 and fuel level sensor
unit terminal 2 (TD27Ti engine) or 1
(ZD30DDTi engine).
Continuity should exist.
3. Check continuity between combination meter terminal 13 and ground.
